after toying with the settings for a while this is the best I could do from your raw file:

Re: DSLR used for astrophotography???
Hi there,
I've read this with interest. I like to image widefield nightscapes with my old Nikon D90 and a 14mm Rokinon lens. All of my dollars went into the lens.. the camera was used, and about 125 bucks.
Notes -
This is a camera with no live view.
10 Mpixels
Manual focus
Single 30 second exposure
Processed for exposure and contrast only in Lightroom CC.
Thus is untracked, camera sits on a ball mount on a static (Vangard) tripod.
Why I'm showing you this is because its a great way to get into
Kind regards,
Fracs: Stellarvue 70T f6; SW 120mm Esprit f7; "Mark Mk. II" - 60 mm Tasco f6; C80 frac f 11.4
SCT: C8 Edge f10 or f7 with reducer
Dob: 14.5" homebuilt strut dob (f4.5 ZOC mirror), Nexus II, Moonlite focuser
Mounts - Ioptron Skyguider pro, Astro Physics GTO900
Cameras and lenses - ZWO 2600 mc, 290 mm mini, Canon 60D modded with Rokinon 10mm 2.8; Rokinon 135mm f2

Very helpful - thanks.
I've tried a few image editing programs and have been able to obtain "decent" results. I've been only using the raw file that I posted in Google Drive. Since I've no clue what I'm doing, all I end up doing is adjusting things until I feel the image shows more realistic detail. I read a tutorial by Allan Hall on
Stupid question - is there some "method" you use or a set of controls you use all the time - or is it dependent on the image you are working with? Also, how does on figure out what "things" to adjust during processing?

Re: DSLR used for astrophotography???
if you’re asking my opinion as a professional commercial photographer then each and every image needs different custom raw to jpg conversion settings - i can’t really articulate the method i use because it’s based on experience from editing 10’s of thousands of images, but it is based entirely on personal preference of aesthetics.lsintampa wrote: ↑Mon Jan 20, 2020 6:30 pm Stupid question - is there some "method" you use or a set of controls you use all the time - or is it dependent on the image you are working with?

Re: DSLR used for astrophotography???
I have an old Canon 350D with no live view and no tracking.
Astrophotography in my experience can be super frustrating to the point you may think it's just not worth your time and effort however it's a great hobby to learn.
I'm no expert at astrophotography but I'm slowly getting there I think. Here's my effort of the Orion nebula taken with my 200mm telephoto lens. I stacked 88 one second images in sequator and processed in photoshop (which I'm still only learning)
Stick with it.....you will one day nail a target that grabs you and that's when the addiction begins!

This area i find isn't as dense as the other side of the milky way and light pollution will cripple signal pretty bad, usually need a few hours to stack.
you still might want to work on your focus ,i'm seeing airy disc shaped stars.

Re: DSLR used for astrophotography???
Abandon the use of jpgs, they're of little value, just record raw files in your camera, switch off jpg recording.
Get as many captures of the target as you can subject to time, sky movement constraints etc.
Put the lens cap on and capture the same number of darks at the same camera settings.
Leave the lens cap on and capture a rake of bias frames. (fastest shutter speed)
Stack the lot in
Stretch the fits file with levels and curves in
Export as a png file and show it off.
Then as time goes on there's 100s of more steps to add! Bit by bit.
Good luck
Regards

aperture were set at?
It's not a very good lens if I'm honest but it's good enough for me at the moment.

So if I upgrade myCG -4 mount with the dual axis motors, can I mount the camera to thecg -4, say with a 200mm camera lens? I've read somewhere that the camera won't be aligned when mounted that way.
If you can find the reference, post it. It sounds wrong.
If the mount is polar aligned, anything driven while on the mount is also polar aligned. Perhaps the comment you read referred to

If the mount is polar aligned, anything driven while on the mount is also polar aligned. Perhaps the comment you read referred toGOTO alignment? I mount camera with 135, 200, 300mm telephoto lenses straight onto my Takahashi EM200, the mount is a clone of the Skywatcher EQ6. The principle is the same for a CG4. I do the polar alignment using APPS, Artificial Projected Pole Star alignment, then put a star dead centre of the field of the tele lens using full magnification live view and do a one star alignment in Sky Safari. From that point I have bothGOTO and precise polar alignment.
