Thank you for sharing your knowledge - too many people out there think they know it all and are unwilling to share what they know.
Wow! I'm a really beginner in astronomy and i've been looking for this explanation for a long time here CZcams. Thank you I really appreciate it!!!
👍👍
Additionally I like how you convey the relationship between the 9mm visually and the barlow. So true.
Yes, they are versatile
One of the best Videos on YT - explained in detail, including links to components.
Thank you!!!
I wish i ould have found your videos sooner. Finally somebody who actually shows you how to set things up, like step by step. I'm sure many people like my self feel so clueless going into amateur astronomy. I learned what little i know the hard way. I have subscribed and look forward to your future videos.
Thank ypu and welcome aboard. You can ask questions during my live streams as well 👍
Never seen this demo before. Excellent review and setup. Thank you.
👍👍
THANK YOU BROTHER. I just purchased the purchased my first telescope (celestron evo 8 hd) and I'm so ridiculously overwhelmed.
congrats. take it slowly
It doesn't get any better.
I’m planning to start with planetary imaging. And will get me a 2x and 3x explore scientific Barlow. And the ASI 715. Can I use the 2 Barlow together? And will it be a 5x 3+2 or is it 3x2 so it will be a 6x Barlow?
yes you can. it will be 3x2=6
very helpful. underrated
Thanks JB !!
Can I use a 3.2mm eyepiece to look at the moon with my 8 inch dob or is it to much power.it will be 375x my max is 408 thanks!
yes you can :)
Dobro!
Can I attach a canon camera to a Barlow? I have a t ring and adapter but it seems I can only image at my base focal length
I don't use dslr so i can't help you but uou ahould be able to use a barlow, i use in all my astro cameras
Thanks for responding, I’ll keep looking 👍
Doing astrophotography in India is very expensive. 😢
Love From Indian 🇮🇳
I know it is, unfortunately. Hope you can do something simple without spending too much. ❤💪
@@DobsonianPower Yes you are right, I have captured almost all the planetary observations on a low budget, and now 93k people have joined my channel, now they are asking for deep sky. But all this is difficult due to lack of goto mount...
Hi I tried to use my Zwo224 with my 10 inch flextube and a 3x Televue barlow and with the original USB3 cable and ASIair Studio program. Got a good view for one second of Jupiter, but then there was a connection problem and I failed to record. And my laptop failed to recognize the camera.. Got new much better cables, and tried to download new ASIair drivers. Was it the bad cables or old drivers do you think ? Can you reccommend a better capture program with this camera ? Or capture method ?
Yes. Download and install sharpcap. It's much better. 👍
Hi, I'm new to the channel, new to astronomy. I have a question about Barlows. They vary in price a lot, is it because of quality difference or is it just because of brand names and no-name? Is it important to get a good quality Barlow lens for good observation experience? Thank you. Love the channel, bought an 8" dobsonian telescope because of you :)
it's the quality. I recommend the explore scientific i have in my website, not too expensive but with quality dobsonianpower.com/
Cool video. Merry Christmas
Hey Garnett, Merry Christmas 🎅
If you unscrew the end of barlow put it in the eye pice can it scratch the mirror in the diagonal that’s what Iv been told?
That will depend on the diagonal. If it's good, it should have a stop ring inside. Check it
My photos look like your smaller Jupiter photo with a 2x Barlow lens. Usng 90 mm with 20 mm lens.
Hello sir ur video helped me but can I use these in piematrix 76700
You can use a barlow with that telescope
How do I get surface detail on Jupiter? Because it looks like a white ball to me.
What telescope and eyepiece are you using?
How do you stack it?
This: czcams.com/video/CKKw9fQGJRM/video.html
7:19 can you link me the adapter and the extended piece if possible please ? there are to many brands online i am afraid to buy the wrong ones XD i already have the ir cut filter
You have them all at dobsonianpower.com/ check there. The extender comes with a set.
@@DobsonianPower thanks i will check it out
If you have any doubt just ask 😉👍
@@DobsonianPower i will thanks
Thanks for the great video..
Does back focus distance matter when you are doing say Moon photography with a Barlow?
When you insert the barlow apart from magnifying the Moon, it will move the focus plane out so the distance from the telescope to get focus will be higher so you adjust the focuser. Just a distance matter, was that your concern?
@@DobsonianPower the other night I had the 2x Barlow in and swung over to a star to focus.. the star was in as focus as I could get it but it was VERY elongated... I assumed I didnt have the right back focus distance so packed up and quit.
@@timliscum2861 hmmmm. What did you use exactly? Eyepiece and barlow brand, focal length and what camera? Is it a goto?
@@DobsonianPower This is for photography,, EdgeHD 8 - 2X Powermate - ASI filter drawer -ASI462MC planetary camera - on an EQ6R Pro mount - Sharpcap software.
It's good material. Should work. Are you using the camera inserted directly to the barlow without anything within?
So for the camera, the 55mm backfocus is just achieved right out of the Barlow? I find that hard to believe, but had to ask.
I don't understand your question. 55mm backfocus for what?
@@DobsonianPower The camera, there's a 55mm backfocus required for cameras
@@ryanmichaelhaley You may be making a confusion with the backfocus needed for other tools like coma correctors, focal reducers,etc.which many require the 55mm backfocus to the sensor but not always that value. In this case it's only the camera and a barlow which moves the focal plane out.
@@DobsonianPower Thanks for explaining that, I've never heard that! Yes, my telescope has a coma corrector and a field flattener, and the scope requires 55mm backfocus to whatever you attach to the back of it (though I never use an eyepiece). There's so much information it's hard to keep it all organized, lol.
Ah, ok. I understand. Those 55mm you got to have from the coma corrector to the sensor. Tell me please, is it an unique piece? A coma corrector with flattener? Or 2 separated?
I have 2 barlows & can't see out of either of them. All I can see is something like a stucco texture.
make sure you insert the barlow first, then the eyepiece into the barlow. Test with the Moon first, you will need outward movement in the focuser to focus with a barlow
@@DobsonianPower done all that. didn't help.
@woodswalker88 what eyepiece and telescope are you using?
@@DobsonianPower Orion Observer 134eq and 10x eyepiece
@@woodswalker88 10x or 10mm?
What about DSLR into a reflector 150pds skywatcher T2 prime I use a badder eyepiece at moment too heavy I want to decrease weight
Ufff. A dslr will increase weight. It's much better a small astro camera for you, like i use.
@@DobsonianPower sorry should have said I use a Panasonic Lumix DMC g9 mirrless
My badder 2" 5mm eyepiece and extension tube is half weight of camera
@@patterdalezipsuzilil for imaging you just need a camera. You can balance the telescope adding weight at the bottom...
@@DobsonianPower not enough I do moon need to get up closer than just prime focus at moment Iam 2 X crop sensor so my telescope is 1500 with out and mag then I use 20 mm part of badder and 4 X idynamic zoom in camera so I on about 15000mm focal length I just wanted to use a Barlow straight onto camera body don't want get one if I not gonna get inwards focus
Me and my Temu telescope watching this:
