Description

This is a result of my Orion HaLRGB mosaic. 8 panels processed out of a total of 24 panels. 

During the course of the last two months, I decided to switch my mount and found a Mach1 local and a good friend of mine offered to bring it to me to save 6 hours of travel. It was a big help! The mount is a solid performer, I got it up and running once I got all the parts/accessories and finished PEMPro and it has literally faded into the background. Ended up doing spring clean up of several AP items as I have been holding on for quite a bit. 

I guess I could call this the first light of this mount. Partial, as all of the Ha was collected when I had the EQ6.

I was not expecting to get RGB data this season with the weather being so unstable, but got a string of clear nights end of Jan and into the second week of Feb. Decided to take a chance and get 1 hour each of RGB and 2 hours of Lum on 8 panels. The last 3 panels were shot during partial moon, and I think I was over confident in my DBE skills. After pre-processing in PixInsight (Crop, DBE) and dropping them in APP, it did not blend well in APP and I think I would tried atleast 10 times and was at a point where I decided to give up on the mosaic and process the panels individually and push it out. 

Went back to David Ault's trapped photons site and decided to try ABE instead on all of the panels. Went through multiple passes at varying function degree and global deviation and it flattened out the MasterLight of a channel. Final test was in APP and when it finished, it looked normal to me. Ran the remaining set of data and then went on with processing. 

I knew what my limitations were, less data and less number of subs. This region is a sat magnet and if you zoom in close, you will see their artifacts sprinkled across. I did not push the data too hard, just enough to show the colors, dust.  More or less an RGB look with a hint of Ha blend.  I also collected shorter Lum exposures for M42's core, but when thrown into the mosaic, I just could not get the details back via HDRMT. I may process that panel alone soon. 

With this region setting below the horizon fast now, I am not expecting to get new data, but will try when there is an opportunity and will visit this again next season and continue collecting data on the remaining panels. 

Hope you like this result. Clear skies!
