So I am not overly disappointed in the clarity of my image. Resolving power of the 4 inch refractor is about 1.015 arches at 500nm whereas Hubble has about. Lies in the constellation Canes Venatici, and was the first galaxy to be classifiedĭistance to Earth: 23.16 million light yearsĬoordinates: RA 13h 29m 53s | Dec +47° 11′ 43″Īlso, this close up is from a much larger wide field image so it won't have the clarity from that stand point. Interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an Seen with binoculars under very dark skies.
Is interacting with its much smaller neighbor, NGC 5195 the two galaxies may be It is one of the most conspicuous and best-known spiral galaxies in the sky. Messier 51 (M51, NGC 5194) is the famous "Whirlpool" galaxy in Canes Venatici. SII (3nm) 15 Frames x 1800 Seconds -15C 1x1 bin
OIII (3nm) 13 Frames x 1800 Seconds -15C 1x1 bin Hb (3nm) 13 Frames x 1800 Seconds -15C 1x1 bin Ha (3nm) 13 Frames x 1800 Seconds -15C 1x1 bin However, it does pretty good and revealing a lot of the data that Hubble does, eve though without the clarity.Ĭompare to the NASA Hubble Images on this page. Unfortunately I can't compete with the Hubble, it is outside our atmosphere and has a huge mirror compared to the little 4 inch lenses on the AP refractor looking thru a thousand miles of atmosphere and city glow.
