Nice one Greg.

Great colours in the clusters! And the structure in the galaxy is really distinct for a 40 minute capture.

Regards

Graeme

Excellent Greg and thanks for your contribution. I see in your image of NGC 2903, you also pulled out the star forming region NGC 2905 - the tiny knot at the end of the central bar just right of the core. Well done. :)

And you did good by staring your own thread. I prefer that as it better highlights the individual accomplishments of the contributor.

Thanks Alan. I think the 20 minutes of Ha data really helped to define NGC2905.

In terms of galaxy observing, I really do like NGC 2903. At our dark site I can see it in the RACI finder and it reveals delicate spiral structure in the 17.5 inch. Not the in your face kind of M51, but its unmistakable. NGC 2905 is seen visually in that scope as very small concentrated brightness off the end of the bar. It is a beautiful galaxy and makes a fine target.

I enjoyed how your images truly highlight the differences between M44 and M67. They really bring home, to me, why I much prefer M67 visually. Again, well done!

Nice images Greg and you illustrate why M67 is one of my favorite clusters to observe through a scope, as M44 (Praesape) is almost more impressive in big binos than a scope. Also a great capture of NGC 2903 and 2905. While I have observed 2903 through the 10", it has been awhile. My log shows 2015. But considering how it is a bit isolated and off the beaten track of M65/M66 it's certainly one that deserves more attention.
