here's a couple from when i first got the dsi...my problem is polar allignment...the most i can manage is abut 12 seconds b4 the image starts to trail..the tarrentella neb with some tweaking in photoshop...a small cluster( im spewin i didn't record which one it was.
...beginner....but its near the tarrntella)..and the last on is the crab nebula..M1..it was quite a difficlt subject...im not sure if i had the settings wrong that night or something, but this was the best of a string of quite poor images....its a steap learning curve..i just use the dsi stcking software...you almost nailed the eta carina hey..im am deffinatly no expert, but perhaps if you reduce the gain slightly so your stars don't burn out so much....still...a hell of a lot of information in the shot...are you useing a focl reducer??
cheers
