Is that 15 seconds in all directions?

Or are you working with a very long focal length

From what I've done so far, yes 15 seconds, and still a bit of trailing in some frames. Might try 10 seconds instead. I have a 6se, 1500mm

So it seems like the most my telescope can handle is 15 seconds consistently. What are some targets y'all suggest, or how can I use this the the best of my abilites?

A play with curves could brighten that up and keep the sky background dark and make it look even nicer.

Ok, I'll keep that in mind. Thanks

My take on the Messier 3 globular, with 65, 15 second subs at iso 1600.

Thanks for your responses, I'll totally keep that in mind when I get back to experimenting.

M87. Very new to this hobby, so got a lot to learn. ISO 6400, and 15 seconds. Canon t3i. I included the histogram too for the raw pictures, what should I change with the ISO or exposure to reduce the colour noise? Should I use a lower ISO? Also had full sets of calibration frames. 40 lights.
