That's looking really good. Nice star color. A little noisy but more data will smooth things out. You might also start doing flat fielding to ge an even illumination in your shots. Other than that you're well on your way. Very nice work.

Hi Tom, nice image there - I don't think it's M4 though, looks more like M22?

Lovely image there, but Rolf's right, it's definitely of M22 in Sagittarius - the group of bright stars to the left of your frame are distinctive on software and charts (the two brightest are 24 and 25 Sagittarii, half a degree west of M22).

Nice grab Tom. I too was out last night appreciating the calm, cloud free night.

Thanks for comments,
M22 was 240s at ISO 200.
Starfield also ISO 200, 600s.
