First RGB/Ha Image

Finally, a clear night that was not below -15C/5F. It’s been a tough winter here in Minnesota. Back in January I got a Mini ZWO filter wheel and filters for my ZWO asi178mmc camera and just recently got a chance to test the new setup. During this period of no-imaging, I was able to build a Dew System for both my guide and main telescope and review my cable management (more on this later).

I wanted to image a simple target and test the the overall function of the filter wheel, focuser integration in EKOS/Kstars. I didn’t want to spend a lot of time imaging as this was a test. So, the simplest and colorful image to test the new setup was Imaging Orion’s Nebula (M42).

The M42 images were taken using the following exposures:

  • Red – 8 x 120s
  • Green – 8 x 120s
  • Blue – 8 x 120s
  • Ha 7nm – 5 x 120s
  • Dark , Flats, Bias Frames processed.
  • I used Astro Pixel Processor (APP) for processing and did some post processing with Adobe Light room.

Below Shows the results:

I am sure that I can process the image data better, and will go back and examine the overall color processing using APP. I will get the process flow better and there are some questions regarding the Ekos focusing routines that I need to better understand and setup as I found that Ekos was focusing quite often during the imaging. I also used the Ekos Scheduler to execute the image capturing process.
