At a distance of 25 million light years away, M-106 is a bright spiral galaxy with about the same tilt angle as the Andromeda galaxy. This galaxy measures about 30,000 light years across and glows at a magnitude of 8.4. Like M-77 in Cetus this galaxy is a type II Seyfert galaxy. Pierre Méchain found it in July of 1781.
Nearby there is a 12th magnitude edge-on spiral galaxy (NGC 4217) among a group of bright foreground stars. In years past using a 10" scope, I was able to spot this galaxy before the urban sprawl erased it from my sky.
Sketching:
M 106 (NGC 4258)
Date and Time: 5-18-2009, 4:50-5:25 UT

8”x12” white sketching paper, 2H, HB, 4H graphite pencils,
blending stump, scanned and inverted
Seeing: Pickering 8/10
Transparency: Average 4/5
Faintest stars visible overhead 4.3
Temperature: 10°C (50°F)
Galaxy magnitude: 8.4
Distance: 25 mly
Location: R.A. 12h 19m
Dec. +47° 18'

Frank,
A wonderful sketch of a very nice galaxy to view. I know from my home I can still see it, but I fear in ten or so years that may not be the case. I also like the purple border your using.

T5 and Jay,
Thank you both.
Tommy5- Likewise I hope you are getting in some observing time. The transparency has been good. Saturn has been impressive. I enjoy observing it when it is near east quadrature.
Jay- I hope your sky holds up for many years to come. I really look forward to galaxy hunting each spring but I find the drives to truly dark skies have become quite long.

Rony,
Thank you.
This is a nice large bright galaxy. I can't see this one with 4 inches or less aperture.

Here is another galaxy I captured last night.
I used a larger scope to get at least some detail on this galaxy.
NGC 4565 The Needle Galaxy in Coma
I observed this fine galaxy 2 nights ago with a 10” Newtonian/ Dob. The night was very transparent however my yard is in the urban sky glow of Chicago so I did not expect too much. I tried again last night with a larger scope (18” Newtonian/ Dob). This time the view was better although I needed to stay with the eyepiece for an hour to get the galaxy to show its features. I have observed this magnificent galaxy from truly dark skies using much smaller but more effective scopes; never the less it is nice to know I can still reach this one as the area in which I live has become totally urbanized.
Sketching:
NGC 4565
Date and Time: 5-20-2009, 4:15-5:20 UT
Scope: 18” f/5 Dobsonian. 24 mm eyepiece 95x
8”x12” white sketching paper, 2H, 4H graphite pencils,
blending stump, scanned and inverted
Seeing: Pickering 6/10
Transparency: Average 4/5
Faintest stars visible overhead 4.4
Temperature: 15°C (60°F)
Galaxy magnitude: 10.4
Distance: 53 mly
Location: R.A. 12h 36m
Dec. +25° 59

Frank,
An excellent observation of NGC 4565 (Needle Galaxy) in Coma Berenices. This is an outstanding edge-on galaxy to observe, especially in larger apertures. Thank you for sharing it with us all.

Nice sketches, I especially like the one of the Needle Galaxy. You've captured the dust lane very well. I'll be posting my own sketch of it soon, as I was sketching it at the same time you were.

Excellent sketch and a favorite object of mine. There is something about an edge-on with the expanse of the in-plane view that is breathtaking to me. Roland

Roland,
I agree with you fully. All those stars across all that edge on distance. I get the same feeling on a clear summer night looking toward the center of our own galaxy. It boggles the mind. Thanks Roland!
