Processed version of my B&W photo M42 Orion Nebula from 4/1/2020 – lights and darks – I didn’t have any flats to hand.
This image has been taken with ca. 30 light frames only 5 secs long, showing how much more sensitive the Altair 183M mono camera is than my QHY10 one shot colour camera!
- Altair 183M mono camera.
- Sky Watcher Equinox Pro 80mm OTA.
- EQ6 mount.
- Astro Photography Tools (APT) software to take photos, Nebulosity 4 software to stack photos and some early processing, GIMP to do further processing.
This post follows on from previous post below:
First image of M42 – with Altair Astro 183M mono camera on EQ6 mount/Sky Watcher Equinox 80mm Pro telescope
Focus position on Sky Watcher Equinox Pro 80mm with manual filter wheel for Altair Astro 183M mono camera – for future reference! As found tonight….(First picture showing Capella when I focused on it in APT).
I have taken my first ever image of M42 tonight – using my new 183M camera
Due to problems with balance of the cameras on the scope I was limited to 20 sec exposures tonight (I just replaced QHY10 with 183M which did not work re: balance!)
So this is a stretched single frame without calibration frames.
Note that data from multiple sub-frames for above image was processed and published on this blog on 8/1/2020 – to view, click below:

Initial focusing images – Astro Photography Tool (APT) works better than Nebulosity – with ASCOM driver v2 from Altair.
This was also a chance to align the main scope with guiding scope.
