- I get a lot of messages from people starting out, that are really thrown off when they look at that first image frame and how underwhelming it is. I hope this video helps.

While I no longer consider myself a beginner, these videos are still super entertaining to watch! I couldn't be more thankful for Trevor's tutorials and astro-basic videos, and truly did help when I was just starting out with nothing but a camera and a plastic tripod. Thank you so much!
Thank you, Josh!! Clear skies

Thank you bro. I took images of the Milky Way galaxy and Andromeda with my Sony ZV-E10. I can see little data but thought something I did wrong. After watching this video my way of thinking has changed.
Nice vid. Would be interested in a full, complete image processing video from the very beginning to the end even in an hour video.
Have a look at Nico Carver's channel. He does long, detailed and informative 'how to' videos. Make sure you have a pad to take notes. 😊
@@givemespace2742 I just started this beautiful journey of Astrophotography
Thks for the suggestion
As a friendly reminder for those using the DSLR method, always double-check that your RAW picture quality is enabled. One time when I first started, I forgot to switch it and all the photos were still dark after editing (and incredibly noisy). I couldn't figure out what was wrong until I saw the ".JPG" instead of ".CR2" at the end of the file names.
I did this myself at the very beginning! I was spitting feathers with frustration, wondering what on God's good earth I had done wrong, then like you, I finally noticed "JPG" on the files! LOL I'm a few months in now, but still have a lot to learn! Clear Skies!
So when you take a RAW picture you know it's a file of that type because of the .CR2 extension? As a beginner who just edited my 1st astrophotography photo using lightroom, I'm very confused and lost. But I'm also impressed due to the difference after edit, I can see a few night stars clearly, before edit not so much.
I used a Gcam mod (BSG 8.9 I think), turned on an option relative to RAW format in the advanced settings, I thought that was enough to save RAW files but now I'm not so sure after your comment because the original photo was .jpg, not .cr2. Also, I don't know if that's normal but the size was small, only around 700Kb.
@@agrillhasnoname that .CR2 file type is only for Canon-branded DSLRs. Each camera brand has a different file type. I double-checked what Gcam is, and I'm assuming you are using a Google phone for the photos?
@@agrillhasnoname if you do, your phone might be saving them as .dng files. With my personal experience using a Google Pixel 6, I wouldn't necessarily recommend using RAW unless you are doing planetary or moon photography. The RAW images in astrophotography mode are still very noisy. It may be because it's using a high ISO though.
Thank you so much Trevor. These concepts have been mingling in my mind for the past few months since I started this hobby last October. You have really cleared up a few things for me. Thank you.
Definitely love seeing these videos from you. Just delving into the hobby after arguing with myself for an hour before investing in a rather small setup and starter kit, your videos are incredibly helpful.
Oh man, this video made me feel so much better. Over the weekend I spent 3 hours photographing the Orion Nebula only to receive a black image in Siril. Even though I was able to get an OK picture out of it, I thought I had messed up. Glad to know a black screen in linear mode is nothing to worry about. Thanks!
I appreciate your amazing insight. I'm new to this hobby. There's so much to learn. I like how you cover the details but it's not so complicated you lose your audience. Yes, I look forward to learning more about the calibration, full black & full white baselines. I've only heard on astro-friend mention it. That video would be helpful.
Thank you so much for providing all of this information to us newbs. My ignorance about this hobby is astounding, and you and others like Nico at Nebula Photos, are doing so much to correct this.
This video is incredibly helpful and inspiring. You’ve made this endeavor mentally approachable for so many of us. Thanks!
As someone who still don't have sophisticated gears like these (still uses mobile phone lol), I grow my admiration for astrophotography and even just the night sky because of the things and contents you constantly share to us, Trevor. There will be a day that I'll have my own, just enough to improve my enjoyment for this hobby. Keep this up! Much love brother. For more clear skies. Thanks for inspiring many people.
Really great video. I'm quite new to astrophotography and my reaction to my first stacked dso image was basically this. Then I did some reading on the processing steps and watched tonnes of yours and others astrophotograpy processing videos. Just upgraded my camera from a DSLR to a DSO camera, the sv405cc from Svbony. Very excited for some good weather here in Sweden. Clear skies
i love this channel, your astrophotography is first class but i love your video editing, nico carver from nebula photos for his in-depth knowledge and luke from lukamatico for his simplistic approach to processing, you are goats to your approach to astrophotography 👍👏👏👏
Hi Trevor! Missed your videos. Glad you've uploaded another video reviewing the basics. Forever grateful to the amount of knowledge I gained from you to help me kick start this hobby :)
The last 25 sec is really beautiful the music and all the details showing up!
Wow! This is extremely helpful and reassuring! It does certainly get discouraging when you feel like you keep messing up. Thanks for the kind and inspiring videos!
Very informative. I can recall using my Nikon D3100 and ED80 in my early days, and being bewildered as to why I had a dark bottle green image with no perceivable data. Wish I'd have seen a tutorial like this when I was starting out.
Spot on Trevor
it is just amazing how astrophotograpy has evolved over the years.
This was so great to find, thank you. As you said, I thought something was wrong with my camera (or myself), and I only saw black shots. when I pulled a single frame into gimp and stretched, I was at least able to see something. Cannot wait to see it after stacking now. Please post more tips and how-to on astrophotography.
Thank you for this video. I am a beginner and lost quit a bit of confidence when I first saw my pictures. This helped me to get some of that back! Thank you.😃
I'm taking an observational astronomy class in college and we just covered image processing and it's crazy what you can capture when you simply know where to look and how to process the photos. my mind is blown every time I take out my camera! Thank you for the videos and helping me get an A in my class!
This is why I love ASIAir and live preview. Then taking them in to Pixinsight to process never gets old! Another fantastic video, Trevor.
Loved that outro of M31 getting better and better! You and that galaxy is why I got into this hobby. Thanks Trevor!
The Timelapse at the end was amazing! Great video!
Awesome video as always Trevor!
Great video as usual. We actually got some clear skies here in Melbourne, Australia for the first time in nearly 2 months over the weekend, so went out with the Meade LX85 8" ACF and Canon 650D. Did just over an hour each on M104 (Sombrero Galaxy) and NGC5128 (Centaurus A), where I got some good data. I wasn't happy after initially stacking because I just had lights, darks and bias frames, as I have never done flats on my SCT. I went back out the next day and re-set up my scope with a t-shirt over it and did 25 flats, and it removed nearly all the vignetting and gave me a much better, more contrasted base stack to stretch.
So, a couple of things for beginners and those a couple of years in to their astrophoography journey - don't skimp on the flats. Particularly if you are shooting from suburban skies like my high Bortle 6 skies. Secondly, if you are using a DSLR, make sure you switch all the lens correction and compensation off before your sessions. I have a full night of shooting ruined recently because I left this on and it made removing the vignette impossible (I was using my full frame DSLR which made it worse).
Thank you so much! My son and I have started this hobby and needed this video!
I was on Amazon looking at Astro cameras. A guy gave a camera that cost around $1k a 1 star review. He said he couldn't even see anything on his computer. He thought he could just look at his laptop and see nebulas and galaxies in real time. He said if knew he had to take a bunch of photos and process them he would look at pictures of these things on the internet. I couldn't believe that someone could be that far down the line to buy a $1k astrophotography camera and still know so little. I just go my first EQ mount yesterday to slap my mirrorless camera on and I knew better. I have been doing photography on and off as a hobby for about 10 years now. I have experimented with star trails and other long exposure photography.
A big THANK YOU from Austria Trevor! Your educational journey is so much appreciated.
Hey man just bought a EOS 7D and I love your videos !! It has 3 kit lenses and I thought they were useless but your videos on them are so good . Love em!!
Thank you for sharing…. I’m curious about the universe and astrophography is one if my new adventures. I was a bit bummed at first not getting to interesting pictures…. This was a great help to improving and learning. 😊
I’m a beginner in this astrophotography and I appreciate these videos..
Thank you. That is reassuring for me. I have most of the gear and need to get my SUV back on the road so I can start learning how to do this.
Well done, Trevor! I'm about two years in now, but watched a lot of your videos to get started!
Thank you!
Thanks. Just started taking pics. Good to know.
This helps so much! As an amateur, I really find this helpful!
That final image reveal was super slick!
Thanks man! See you in PA this summer?
@@AstroBackyard yessir! And possibly sooner? My fiancée and I will be at neaf in a few weeks! But it's a big place and we'll be doing other things in the area too. But if y'all wanna meet up for coffee or a drink, hit me up!
Although I occasionally take night sky images, I am just starting out and beginning to have an interest in astro. This video was very useful to this 'newbie". I'm looking forward to learning more.
Your pictures are amazing, I am a biginner astrophotographer and your videos show us the viewers how amazing astrophotography is and how beautiful space is🌌🔭 clear skies.
Again what a great video thank you so much for sharing the journey you took. I recently started working with Siril. I'm still in the beginning steps of my astrophotography and some tools are very expensive. For me Siril got all the tool together. After Siril i'm still using GIMP to do the last processing. What do you think of the Siril tool and could you make a video about it?
Great video again! I've been getting 300 sec exposures with the 294mcpro but I've not learnt how to stack or process yet. Even the single images wow me
Super helpful! Thanks!!
Thank you Trevor. I can’t wait for your PixInsight tutorial
Trevor, your into on this video is hilarious!!! I think every astro photographer has experienced that moment. I think my problem is I don't spend enough time collecting data. Something I personally need to work on. Great video!!!!
Around a week ago, I started trying to capture some objects of interest with my DSLR (w/ 18-55 kit lens). And yesterday, I figured I'd try out stacking, and took 10 straight shots back-to-back and put it through DSS. Ngl, when I first saw the stacked TIF, I was like "wtf, where did my image go?" 😄
Yet to do post-processing on it. I want to see some tutorials from your channel and other sources first before trying to edit it. But this video really helped me be more optimistic about what I'm going to uncover during the post-processing. Thanks, Trevor. :)
very useful, really a great job!
Absolutely amazing
Wow, Beautiful video !!! Thank you for your videos !!! 🔭😁👍😆👍😆
Thanks Trevor great info, I would have been very disappointed with my first shots and wasted way too much time working it out without your video.
Great explanation, Trevor!
When I did my first shot I was amazed how much money I spent to have a 10s exposure of some stars.
It took me quite a while to figure out how my whole setup works. It took me probably 5 nights to figure out how to properly align the telescope. Then another 6 nights to get the tracking right to have >30s exposures and how to capture and edit Images.
I can't wait for this Summer to finally shoot an Image I'll be proud of 🎉❤
Nice video Trevor! Just finished (hopefully) shooting Sh2-240, the Spaghetti Nebula, over 4 nights (about 18 hours integration time). Such a dim target! The first stack of only 2 nights of data did not reveal much, even with a good camera (2600 MCPro) and L-extreme. Adequate integration time (and lots of patience) is key.

Thanks. I needed to know that :)
THANKS FOR THE HEADS UP ON THE DSS UPDATE!
Great video, Trevor! I was wondering if you could make a new video tutorial on using the Star Adventurer GTI in conjunction with a standard camera, and maybe showcase some examples of what kind of shots you can capture with a 70-200 mm lens
so good!
Great video Trevor 👍
I remember when I got my Osc camera, I freaked out when I saw the linear data. My next purchase was pixinsight and I love it, creating a dynamic image like the foraxx pallette is sublime
Im The Same As A Few Here,Im No Longer An Actual Beginner But Yours and A Few Others Are So Helpful,Im Getting A Canon t3i,Me And A Friend Are Swapping,Im Giving Her My t6,Gonna Make Life Easier…I Have A Crystal Clear Sky,and The Winds Are Settling Down,Going To Attempt My 1st Orion Nebula With My Evostar72,Its Getting Ready To See Its 1st Stars,Great Video Trevor,God Bless You and Your Family,and Clear Skies🙏🏻❤️🔭🌏✨
Fantastic video. Thanks. This is going to be required viewing for everyone in the MSM user group.
Great video as always
Thanks Trevor. Is there a "standard accepted color" for the individual DSO? What color is the Andromeda galaxy supposed to be? Orion Nebula? Seems like it depends on the person processing and/or filters used?
Hello for the fits format there is also the asi fit viewer
As a beginner, these videos are very helpful. A question - when importing raw files into Lightroom, do you turn off the lens profile corrections? Are these also turned of within the camera as well? Ok those were two questions.
I'm just starting to get into mono imaging and I'm having trouble with calibration frames in pixinsight. I want to make a good master flat and bias but I think I'm not capturing properly. If you could do a video talking all about creating really good calibration frames!! Love your work btw!
Hats of u sir 🎓
well, you really are amazing. Thank you
Excellent video Mr Trevor…..I only using my iPhone on my scope ….I haven😢 tried to use the computer to
Try and view the area photographed
Nice video for beginners, a question. If we see the live preview from ASIAir or NINA, will we also only a pitch black image?
Beautiful 👍😁
Hi. I tried getting the Rosette nebula from Toronto. Using a filter, I was amazed I started data from Toronto. The clouds rolled in and I only got 6 lights of the Rosette. When I stacked it all using the asi air-bias flats and darks, I lost a lot of detail. If you dont have enough lights (6) compared to flats darks bias (50)-would that cause the loss of detail?
What is your primary processing software for stacking and cleaning up the image? It looks like you use Pixinsite and DSS and then finish in PS?
excellent
Excellent!
Great Video Trevor, was just checking out the links to the gear used and for some reason the page tries to load and then errors out. Not sure if its me, the website or the links you have posted.
Nice intro-level vid Trevor.
Please do more of these videos
Would love to see a video on post processing images for beginners
Hi Trevor. A wealth of information. Just beginning to get into astrophotography. Getting the am5 and red cat 51. Still debating on cameras for imaging and guiding. Any recommendations would be appreciated. Thanks
@tradde11 Thanks tradde11. Appreciate it. Clear skies
Just what the Doctor ordered. Thanks Trevor
i am pretty much a beginner so what is the best next step in terms of camera upgrade. just throw the ir-cut filter out or a full spectrum upgrade?
Wow, watching that beautiful image emerge with the amazing background music brought tears to my eyes because of how jealous i am that i cant afford the equipment to do anything like this.
Wow ❤
Hi Trevor. Met you at Cherry Springs.
Can you clarify? Do you need bias frames for a one-shot color CMOS like the ZWO 183MC Pro?
I heard you don’t really, just to use flats, darks and dark flats.
Great outro song!
Hello my friend. Thanks for the video. For night photographers who don't use an astro mode camera, we'd appreciate it if you could make a video on how to better bring out colors in milky way and deep space shots, my friend.
Nice vid thanks!
Im super new to taking pics. Using a Canon camera (nothing special) but can anyone help. When i take a long exposure pic and then view the pic, it looks amazing until i zoom in.. its blurred so i assume its vibration/noise? I have a small/short desk tripod and use the countdown option so i aint holding it during xposure.
Anyway i can stop the blur? Thanks :D
Please do a video on calibration frames!
Hi, you mentioned Debayering, when do you Debayer before stacking images? do you do this on every image you do? mannn there's a lot to learn haha
@astrobackyard I’ve loved your realistic/light polluted content for ages. My dad’s anniversary is coming up and I want to get a mount that can hook line and sinker him into astrophotography. He’s so fixated on the andromeda galaxy I want to get him something that will get his imagination going. He’s got no experience other than me (an amateur, at best) showing him the rings of Saturn, so I need a super beginner level rig. What would you recommend. We live in the in south wales, uk.
I remember that feeling 😅but now I know better 😊
Every beginner needs to see this video before they start out
Very good👍
Is the canon Rebel t100 good for astrophotography with a 18-55mm lens?
I've been asking this very question for months, and finally you gave me a proper answer, thanks Trevor! And my goodness, that ending music combined with the beautiful Andromeda galaxy, really moved me! 🔥🌟🪐
Nice vid Trevor. Have you ever considered giving a course on SkillShare, from beginner to expert? Or more than one course.
Hello. I have 20 plus years of photoshop use, but no longer own a copy of it. My question is what would it look like to take just ONE photographic image, make a ton of layers copied from it, and stack those? Tweak it after stacking. Or not? All layers transparent?? Thanks....
I took my first lousy deep space photo the other night. It was M31. Kinda fuzzy spot. Took it into Gimp and stretching it and M110 appeared. I was tickled.
Which monitor do you use for processing?
you should make a step by step guide to photographing the Andromeda galaxy
