I would like to share my third image.

I finally had a "lucky week", since my last session, December 18th. I managed 5 clear nights out of the past 6 (has to be a record, at least for me and my area) and I was able to finish a couple of projects I had started long ago and start a few new ones.

This is M33, also known as the Triangulum Galaxy, taken over 10 nights, under my Bortle 5/6 home sky.
Total integration time: 10h 14m 00s.

Here are the acquisition details:

Mount: Sky-Watcher NEQ6 Pro
Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
Camera: D5300 astromodified
Reducer/flattener: Tecnosky 4 elements, 0.8x
Guide-scope: Artesky UltraGuide 60mm f/4
Guide-camera: ZWO ASI 224MC

2020/11/08: Number of subs/Exposure time: 11@240s. Notes: L-Pro filter, no Moon
2020/11/09: Number of subs/Exposure time: 10@240s. Notes: L-Pro filter, no Moon
2020/11/20: Number of subs/Exposure time: 15@240s + 4@300s. Notes: L-Pro filter, Moon 30% illuminated
2020/11/21: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, Moon 45% illuminated
2020/11/24: Number of subs/Exposure time: 20@300s. Notes: L-Pro filter, Moon 75% illuminated
2020/12/13: Number of subs/Exposure time: 12@300s. Notes: L-Pro filter, no Moon
2020/12/14: Number of subs/Exposure time: 8@300s. Notes: L-Pro filter, no Moon
2020/12/18: Number of subs/Exposure time: 6@300s. Notes: L-Pro filter, Moon 20% illuminated
2021/01/10: Number of subs/Exposure time: 9@300s. Notes: L-Pro filter, no Moon
2021/01/11: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon

Total exposure time: 36840s = 10h 14m 00s.

Pre and post-processing: PixInsight 1.8.8-7.

Image was Drizzle Integrated and then cropped to original sensor size (6016x4016), without resampling. So, it appears as if taken at double the focal length (768mm instead of 384mm). Image scale 1.04 arc-sec/pixel.

Here's a link to the full resolution image: Triangulum Galaxy (M33)

Thanks for looking!
C&C welcome!

EDIT: spelling.
