doubled down on M100 (Halifax)

I continue to double-down on Messier objects. I first viewed Messier 100 on 4 May '13. Had a quick look at faint M100 in the summer of 2018. Sent BGO to the target so to have a good long look at the face-on galaxy in Coma.

galaxy Messier 100 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Wow. What a beautiful spiral. Two main majestic arms radiate from the inner ring. The arms have kinks? They have rich texture with light star-filled regions. Fanning. The core is compact but bright. M100 is also known as NGC 4321.

IC 783A lies to the west-south-west, a small round bit of fluff.

Due east is the large somewhat oval fuzzy of NGC 4328.

North of 4328 is tiny PGC 40214.

NGC 4322 is north-north-east of the big spiral. A dim oval patch.

Wow. An amazing sight.
