Astrophotography With A Dobsonian? 

i dont think you guys understand what is stacking... i have a 3" refractor that is a piece of crap and still get good results, you guys need to learn a bit about stacking and processing...

Lupl

@@guliver21 i don't think you understand how stacking works. It only increases signal to noise, it doesn't create new detail.

@@T0ly113 Tomas is talking star trails though, not resolution. Stacking allows (indirectly) for shorter exposure times, which minimizes/eliminates trails. So yeah, it is possible to get good images with proper processing from a smaller 'scope, better than overexposed blurry raw images from a larger one.

@@KatorNia yeah, you can take like 1000 shorter exposure images of andromeda, stack them all with the flats and darks, and get a really clear picture, processing matters a lot to the final image.

Thank you so much!

Argentina,... wow, I would love to star gaze there

Thank you so much! 🙏

Nice

didnt expect to find you here haha

Thank you so much 🙏 Heh I’m pretty jealous of that 10”. For the time being though mine will have to do! Clear skies!

So the visual you get from just using your eyes or eye is amazing? Just the photos he's capturing are average? Looking at buying 1 just to look at galaxys and stars but all the videos I've watched are discouraging

Thank you so incredibly much! I’m just glad to help out. Cheers!

Thank you! 🙏

Thank you for coming along!

🙏

Thank you for watching!

@@AmateurAstronomyStormchasing I do believe with a traverse base ring gear and a window wiper motor out of an old car, along with a worm gear driven elevator motor, and a way to mount them, you could then use a raspberry pi or even an old laptop to control the motor voltages and amps at varied magnifications, you could track stars for medium-long exposure shots. If you could get it to work well enough, deep sky shots could maybe be possible on a dob. It's what I am going to be trying to do, anyway. Wish me luck!

@@Gun4Freedom i think you need a guidescope with the related software from a CMOS or CCD camera. Hopefully you get it going tho! Clear skies!

@@Handles-R-Lame I like his simple style. Your ides means $$$$$

@@davidbentley1391 well if understand correctly in what hes saying. You will only be able to track movement in Right Ascension. And thats _only_ if you polar aligned perfectly, and then even so were talking a dobsonian which is alot heavier then say a refractor so after it tracks however long it can, it then will have to be repositioned to accurately track the object again. And depending on the motor you salvage it could track to slow or fast or even not smoothly. Im just saying to accurately track the motion of the stars you need a guide camera or else your going to get elongated stars; regardless of what motorized mount you have(even the best motorized mounts, polar aligned perfectly, will be off somewhat especially with long exposures). But hey im not disowning the idea, more power to whomever can actually make this work, besides people have created the barn door method for tracking stars a D.I.Y. project for less then all of our ideas. Literally under 10 dollars. Clears skies everyone!

Thank you so much! Heh I like to keep things as simple as possible on here... glad you found it helpful! Cheers!

Heh yeah, it can be tough at first finding new objects. But it help out so much in the long run learning the night sky! Good luck with the new scope, and clear skies.

that's the same attitude i had when buying my first scope. it would almost be embarassing for me to have just bought a goto and then if it broke or the batteries died, for instance, i would have no idea what i'm doing. with my dob i'm aquiring a new skill, getting to know the sky, and spending quality and peaceful time just stargazing and getting in touch with the creation and my thoughts.

Thank you! 🙏

Heh thanks! I actually got the shirt when I preordered their most recent album :p. Good luck with the new scope, hard to go wrong with a dob!

If I have a 8" Dob. Do I just take it off the original base and put it on the Goto mount?

@@KungFuSlumm way to heavy i think

For the price of a go-to dobsonian mount, wouldn't it make more sense to get something like the 8SE?

@@KungFuSlumm yes that's all it takes. I have the 8" dob on the goto mount

@@jojag5 forgive my ignorance, what is the 8SE?

Planets imaging are achieved via lucky imaging. You basicly record a video (or a series of low exposure images) and then combine those images using lucky imaging algorithms. A single exposure image will result in a fuzzy object (high exposure time is not needed as the solar system's planest are very bright)

You can do plenty of deep sky with an AltAz mount. Just keep your exposures to 30 seconds and under and you won't even notice it. Then stack the photos.

@@wondermom2five Thanks! Yes, I did get the focal reducer and did some DSO imaging with decent results. Found up to 20 secs was optimum and live stacking works well. I have recently added a wedge so now I have an equatorial mount. I haven’t done very long exposures yet but will try soon.

Thank you for watching!

Have you taken any deep space images my friend!

It's a killer scope for such a simple set up! Clear skies!

Appreciate it!

I also have a 6" dob, no canon. I am trying to get my android phone (a oneplus), a ROM to allow me to set exposure time and other settings to exactly what I want, and build or buy a star tracker for my scope. Why not? Maybe I am onto something. Not needing a DSLR to get decent astro shots, just a decent smartphone camera and a mount, would lower the bar for entry into astrophotography for a lot of people. Good luck with your astronomy :)

@@Gun4Freedom hey man, what did you end up doing? I have a decent camera on my pixel and thinking of doing somthing similar

@@williamaudet1235 I got a oneplus 7 pro, used, it has a 48mp camera and a pro mode where you have access to all the standard settings you'd expect from a DSLR. I got an amazing shot of the Centaurus arm of the Milky Way with the setup last year.

@@Gun4Freedom Nice man, I just ordered a mount for my pixel 3a, but I don't think I can change any camera settings on the pixel. My father has some old cameras he let me borrow, a nikon D300 and D70s, I can probably do something with those. The biggest lens he has is a variable 70-210mm or something like that so maybe I can take picture without any telescope. My other option would be to mount it directly on my 6 inch dobsinian but don't know if its possible.

You’re very welcome!

Whenever I get out of quarantine I’ve got a lot planned heh. Hopefully Rosette isn’t too low on the horizon by then 😬

@@AmateurAstronomyStormchasing good job mate. Stay safe.

Thank you for watching!

I agree 100%! I’ve seen where people have photographed planes with their dobs... that’s something I’d like to give a shot!

I’m usually dealing with bortle 5 skies. If I’m feeling up to it I have access for some bortle 4, but it’s a lot of gear to carry around 😅

time. shorten up the time. or change expo if you can. do one thing at a time . lil hint tho.. video them. then make image from it.. theres tons of vids on here so i wont go over it. its kind of best way to do planets is videon them .

Heh I’m working on it 😉. Just don’t like to rush stuff!

@@AmateurAstronomyStormchasing i can respect that brother i get it but it doesn't hurt to wish my friend keep them coming great work!! You are doing stuff I can only wish that I could do!!

If your scope has some threads on the outside of the focus tube, then you won't need a t adaptor. The SkyWatcher dobs have these threads on them allowing you to attach the camera directly to the scope. If your scope doesn't, then you'll need an adaptor as well. I have a t adaptor so I can use my barlow lenses... so if you're planning on using a barlow you will need a t adaptor. Here's another video of mine showing these threads on the focus tube to make it easier... check ~1:38 in the vid: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8607YGFG12Q.html As for the focal length, the focal length of the scope becomes your actual fl. So with just the camera my fl is 1200mm. Adding in a barlow lens or focal reducers changes your fl. Hope this helps!
