Description

After adding some more data on M 74, galaxy NGC 891 appeared out of the branches of my large Shagbark Hickory tree. This is 2 hrs and 50 min of good data. Another rare night of good seeing and an average of 1.6 FWHM ! That may be the best I have had to date.

170- 60" lights with a perfect meridian flip for a total of 2 hrs and 50 min of good data. I did not cull one sub which is also a record for me too. I refocused after the first hour and again after the flip.

Description: This is a 1X drizzle reprocess in PI of the original data I acquired. It is a heavy crop and, I also added some star spikes in via Star Tools. First time use of Starnet2 to really enhance the dust lane.

Description: Another revision but using trial issue of RC Astro's BlurXterminator in PixInsight. The rest of the process was nearly the same as in the 2nd revision, less the star spikes and, the 3rd revision had more star reduction and a VERY light unsharp mask applied.
