First go at Orion Nebular

This is my first ever go at imaging the Orion Nebular.
Using a Skywatcher Evostar 150ED

Not up to the usual standards seen on here, but just starting out.
Still looks a bit funny around the edges of the Nebular.
Used Astro Photography tool for stacking and Gimp for processing.
Nothing fancy in Gimp, just the very basics as i am still working out the program.
Used a Canon EOS 600D, But had no reducer / corrector, might need to invest in one possibly.
But also made the mistake of creating a custom white balance, so colors might be a bit off from what they are suppose to be.
So will fix that next time i get out.

Peter,
That’s a fine image of M42 with the 600D
Well done !!
Just some tips if your interested
Stack all your subs , darks etc.. (Raw Cr files) in Deep Sky Stacker DSS, it’s probably the most popular and versatile stacking software in the world , it’s free and it’s been proven time again to produce high quality stacked images
Never stack jpegs from the 600D always Raw Cr files
Don’t use DSS for processing
I only use APT for image framing, focus and capture
Why not try Startools a go for your image processing, again a very powerful but easy to master processing software
I started Astrophotography just over 4 years ago with my Canon 600D and newts and have used Startools exclusively ever since , it’s great for beginner, intermediate and advanced imagers
For your information.....
Here’s the best Astrophotography settings for your 600D which I found from Jerry Lodriguss (Astropix) a well known American DSLR astrophotographer

Canon EOS DSLR Astro settings with for prime focus with telescope ( Canon camera’s manufacture dated 2004 to 2014)

Exposure - set to Manual
Autofocus - off or Manual
Grid display - off
Aspect ratio - 3:2
Screen colour - 1 or preferred
ISO - sweet spot is 800
Aperture - aperture is fixed through telescope
Shutter speed - Bulb with remote shutter release
White Balance - set to auto white balance AWB ( if Camera has been Astro modded you have to set a “custom” white balance )
Drive - set to single shooting
Colour Space - set to RGB
Image file - set to Raw + JPEG
Image review - turn off
Metering mode - set to Evaluative
Exposure compensation - set to 0
LCD Auto off - set to disable
Live View Shoot Function - enable
Live View Exposure Sim - enable

Custom functions -
ISO expansion - set to off
Exposure level increments - set to 1/3 stop
Long Exposure Noise reduction - off if shooting darks
High ISO speed noise reduction - off if shooting darks
Highlight Tone Priority - disable
Auto Lighting Optimiser - disable
Auto focus assist beam firing - disable
Auto power off - set to 2 minutes
Auto rotate - off
Built in flash - turn off
Red eye reduction - turn off
Dust delete data - set to none or turn off

Picture Style -
Sharpness 0 or halfway on slider
Contrast 0 or halfway on slider
Saturation 0 or halfway on slider
Colour tone 0 or halfway on slider
Mirror lock up - disable

Note : some older Canon cameras may not have some of the above settings so ignore them

Looking forward to more of your Astro images from the Canon 600D ( great camera ) I still use mine for planetary imaging

Cheers
Martin

Peter,
A really good Astro website is Astro Blog Delta ( Astro.equadors.net )
There’s a tutorial there called “Processing a noisy DSLR image stack with Startools “
It runs through the whole process of image stacking and processing using DSS and Startools . Although 5 years old it is still relevant for DSLR Astrophotography using DSS and Startools
A very good resource
Cheers
Martin

Yep, I started out with Jerry Lodriguss' tuts.
One minor change I would suggest is not to use Auto WB
Even though the WB setting doesn't really affect the RAW frames when processing, they do affect the jpgs and what's viewed on the preview screen.

Using AWB could/will result in changes between frames as the camera may decide to switch to a different WB for whatever reason.

I always set my WB to Daylight (Sunny), which would be the closest to natural daylight and gives me consistent jpgs, (I always save both the RAW and jpg files).
As I said it doesn't alter the RAWs for processing.

Of course, if it's a modded camera then custom WB will be best for viewing the jpgs but again, won't affect the Raws.

Thanks heaps for the replies and advice.
Open to any suggestions that will help and also point out any mistakes i have made.

Yes the Canon is fully modified, I had a go at this myself, went smoothly enough.

I was a tad unsure on the custom white balance, I will ask about that in a separate post though.

Appreciate the links and the advice to give Startools a try, will definitely take a look into that as well.
Very much appreciated.
Peter.

From a newbie who hasn't tried viewing nebula yet, I'd be totally chuffed if my first image was as "bad" as you think yours is.

Very impressive.

Good work on your first image
How nice is it to see the fruits of your labour, huh?
Only tips I have is specific to Orion.... take two sets of images. One set for the nebula itself and another for the core, then learn explosive blending. You’ll get way more detail in the nebula and core that way.
