Let's Photograph M106 (Galaxy) - Polar Alignment in SharpCap
Vložit
- čas přidán 15. 08. 2024
- In this astrophotography video, I collect light on a Splendid Galaxy in Canes Venatici known as M106.
Using the Polar Alignment feature in SharpCap Pro, I was able to achieve my best polar alignment for astrophotography yet.
Step By Step Process: astrobackyard.c...
This is a great method for anyone looking to improve the accuracy of their tracking telescope mount.
The field of view produced by the Altair GPCAM2 and Starwave 50mm guide scope is a perfect pairing for this process.
In the end, I was only able to capture about 2 hours worth of exposures on M106, but it was enough to reveal the beautiful structure of the galaxy.
The camera used was a ZWO ASI071MC-Cool, through an Explore Scientific ED102 CF Triplet Apochromatic Refractor.

Trevor very helpful savings us $300 and our knees with sharpcap polar alignment. It's always great to see how videos like yours show how dedicated we are to get the shot!
boo!
it is really awesome to see how many other galaxies there are in this photo as well as the M106. so amazing.
photograph the cigar galaxy. That's going to look amazing.
Excellent vid, first class productions every time! You're an ace
Thanks for posting. I need to get my polar alignment better. I have a Celestron Advanced VX Computerized German Equatorial Mount with a Celestron 8 HD. Can't wait for the next clear night.
I'm impressed you got that image even with all the smoke from the fireworks in the air. That's amazing.
Yes it was a strange night. In the end, it's nights like this I will remember the most!
When I use Sharpcap to align. I do exactly how Trevor did but also it’s good to double check everything by just clicking restart plate solve then rotate the RA back to its home position and then let the second plate solve verify that everything is perfect. After I started doing that, I can even get my cute EXOS100 to do sub arc second guiding.
haha, I was expecting to see a video I got clouded out just like you. I saw that clear patch yesterday and knew you'd probably have a video.
Thank you Trevor, you are doing well with your videos. I look forward to seeing them every time you publish one! Thanks 🍻
i realize I'm kind of randomly asking but do anybody know of a good website to watch newly released tv shows online ?
@Bradley Cyrus flixportal :D
@Lucca Solomon thanks, I signed up and it seems like a nice service =) I appreciate it !
@Bradley Cyrus happy to help :D
Great video Trevor I look forward to seeing every video that you do.
Thank you Vance!
Yet anther great and educational video with loads of tips and tricks. Thanks Trevor and keep them coming.
Trevor THANK YOU SOOOOO MUCH!! Super learning tool again!!
great pic and video looking forward for the next one
Thank you! I was on the fence about buying a polemaster but this looks like it does the same dang thing. I'm going to give it a shot tonight.
Thanks for the great videos and helpful hints and tips.Got my first polar alignment tonight and some photos of the Great Cluster in Hercules.Such a good feeling thank you for you help through these videos.
Hope you catch up on your sleep, but thanks for another great video. I'm assembling an outfit and have been living vicariously through your work. Keep it up, please! Clearskys
If the ancient Egyptians had met Rudy, they probably used his head shape for Anubis! Thanks for your inspiring video.
This is a great example of the alignment routine. Thanks!
+Dennis C Thanks Dennis!
Fantastic videos! Please keep them coming! You're really helping many people become better astrophotographers, including myself. I hadn't tried the Sharpcap option yet, but I will now. Question for you, have you had to deal with cone error on your ED102? I seemed to have issues after a meridian flip. Thanks again!
Thanks Chris! I haven't looked into the Cone error issue yet - very intersting. I will look into it, thanks for bringing that up!
AstroBackyard Thanks for your reply. I learned there are some adjustment screws on the bottom of the vixen dovetail. I was able to adjust those and have a much better result when crossing the meridian. I still need to fine tune it, to dial in GOTO accuracy, but I'm making progress. Thanks again!
great video! thank'u very much for your assistance
Trevor you really do inspire me and intrigue me for this hobby. As I cant afford such equipment right now, I had the idea to at least get a startracker and use it in combination with a dslr + 300mm lens. Hopefully I will get at least somewhat cool images.
Subscribed. Love these really finesse deep space pics.
At 3:20, you answered a question I had. I will need to align my AVX mount using my st80 (400 fl) telescope as I don't guide. Thanks!
Amazing music from Assassins Creed 4, one of the best storylines. In my top 3 for sure. Do a let's play lol
Nailed it. lol about the lets play - imagine an all-night astro session with a lets play while imaging. Mind... blown.
AstroBackyard next time you should live stream it. That would be awesome. Btw this is one of your best for sure, never thought you could get so much color from the ground. But you did it. Great job
Very pretty.
Got a suggestion for you.
Once you run one iteration of Polar Align with SharpCap, recenter the mount in the home position, and restart the Polar Alignment. When SharpCap asks you to rotate the mount on the R.A. axis, go the OTHER way, and if everything is good, you should be centered in the box. If not, you may need to check level on the mount (which, of course, should be done before even mounting the head on the tripod).
Furthemore, after doing your SharpCap alignment, if you can, use the Drift Alignment tool in PHD2 to check your Drift. It should be very close, no more than 2' off, or less, but you can refine the PA with your drift alignment tool. Look for a video on PHD2 drift alignment by Wallrat. He doesn't use SharpCap, just a P.A. scope, but from there, he goes on to show how the Drift Alignment is done.
I appreciate the suggestion - thank you Gary, very useful!
amazing work and presentation trevor, well done, kindly do also show the raw data and then the stacked one before final image...
Thank you. I'll have a section of my website with this photo of M106 and all details up soon. Also - I'll try to include more image details in future videos.
Wow ! Man you're good Trevor...
Glorious!
Just think. 25 MLY and so beautiful an image.
Don't feel bad, here in CT it's been cloudy every night for almost five weeks
Great work!
Your videos are amazing! Thank you very much for inspiring us all! :D
Fine job. The struggle is real.
Hi Trevor,
Looking back...Sharpcap or Polemaster? Also, would you recommend the ED102CF?
Thanks!
Roland
Thanks for the great videos you make helping us 'budding' astro-photographers. I just found this video, but have been using the Sharpcap pro polar alignment tool for a while now. It does take a bit of practice to get those final fine adjustments. If I'm say 12 degrees out to begin I tap the mount leg with my foot first to avoid running out of adjustment with the azimuth adjuster bolts. Did you ever try the Sharpcap pro plate solving tool? I can't get it to work 😕
Trevor, I enjoy the videos. Wondering what the mat you put down under your scope was for. Does it help with vibration or just so you don't loose things in the dark?
Is the guidescope pointing in any particular direction or needing any setting up Trevor?
Wait im confused, he used his finderscope for photographing a galaxy? im sorry I dont know but can someone help me understand?
HI there Trevor, I can't thank you enough for all your informative videos. One question about your polar align procedure using SharpCap: you did mention to proceed with SharpCap BEFORE your normal procedure with the help of the handcontrol with the mount, right? Any explanation for this? Thanks in advance.
Respectfully,
Henri-Julien
Excellent video and demonstration. If I may ask, what video editing software do you use?
Thank you! Adobe Premiere
Ah ha - will take it for a spin. Many thanks.
HI Trevor, Thanks for your efforts here, however I would prefer if we can be quick to the topic. It's more than half way through when you get to sharpcap.
Hi and thanks for the video! I have a ZWO 1600 camera and I was wondering if I would have any luck polar aligning if I put it on my guiding scope which is a Orion 50mm guide scope? I tried to use my guide camera (StarShoot AutoGuider) but don't think it's supported in SharpCap. Let me know what your thought is and thanks again for your video. Pete
Hi, it's really great video...
Just wondering, you're using PHD2 as your guiding software right? If i'm not mistaken, PHD2 has Polar Drift Alignment as well. which one do you think easier to use; the sharp cap polar alignment or Polar drift alignment on PHD2?
I've been using SharpCap Pro with my StarShoot Autoguider and 60 mm guidescope for about a month. It makes PA much easier. I just watch the numbers in the middle and try and get them as close to zero as possible. Following the arrow/target confuses me. I have to use a 5 sec delay with darks on the StarShoot to make reliable platesolves.
Yes! I am going to use the numbers next time rather than the arrow - it was a bit tideous. 4 seconds with darks seemed to work well for me. Cheers
Trev, another inspirational piece with a great closing scene... I finally have gotten my polar alignment under control, and getting good results with guiding. Can a decent DSO image be far behind?
Let me also add that I was up waay too late last night also, and that work was a chore today - but worth it.
Cannucks and Hockey the perfect marriage.
Hi Trevor,great video ! ,can I ask were did you purchase that red head lamp that you are using ??
Great result Trevor, well worth the loss of sleep. just incased I missed it in the video, what was the exposure time of each shot to create the end result?
Is Sharpcap Polar Alignment good for polar align without being able to see polaris? Because my house faces due south
Is it visible spectrum only? Amazing final image!
What was the galaxy in the background that looks like a small smudge?
I ain't no astro photographer, just a regular one ergo have this ridiculous question: How do you manage to make a sharp photo with those 5 minutes exposures?
Otherwise a great video for a noob like me.
Curious, would the PA with sharp cap work with an off axis guider?
Very nice video. Thank you for this.
I just have a remark concerning the pronunciation of "Canes Venatici". You are pronouncing "Canes" as if it were the plural of "cane" as in "sugar cane". But it's actually the plural of the Latin "canis" meaning "dog", thus "Canes Venatici" are the "Hunting Dogs", as you most probably know. The correct Latin pronunciation would be "Cáhnehs Venáhtickee" or "Cáhnehs Venáhtisee", with the stress on the "a" in both words. I've also heard the final "i" of "Venatici" pronounced like the "i" in "sigh", with the whole thing becoming something like "Cayneez Vinatisy", but that's definitely not Latin but English.
Which part of Canada 🇨🇦 are you from ? I used to live in Victoria BC a small beautiful island. Love Canada 🇨🇦
Hi Trevor,
I have been meaning to ask a question on your mount - you are using a carbon fiber 102mm correct? That weighs about 8lbs - do you think your mount could handle an additional 10lbs? I have the 127mm non carbon fiber version which is 18lbs and get mixed thoughts when I ask if the NEQ6 would handle it for Astrophotography.
I have the APO ED127 aluminium. With the 60mm starwave guidescope it weighs 20lbs and I use it on the Celestron AVX mount which is very similar. I hope that guides you a little?
Do you still answer questions to older videos?
hey you're okay i do like your work no hard feelings i get mad now and again, i think its the medication i am on clear sky's bro :)
Excellent video, but can you tell me if it's necessary to have a view of the NCP to use this method? That is the reason I wouldn't be able to use Polemaster.
andicus1 yes this only works with a clear view of the North star and area.
Thank you, Dominick!
Do this again but with something that has a higher FL.
Until recently, I've been doing this with my c8 and a 6.3 focal reducer. It works... OK. However, my finder scope works MUCH better.
Omg whats the first song?
