What you did by focusing on a bright star first then slewing to your DSO is the right way to do it. All objects out there be they planets ( close ) or galaxies millions of light years away have the same focus point ( infinite focus ). So you’re on the right track. Are you using a bahtinov mask when you focus on the star ? That will give you correct focus for your sensor not your eyes as everyone’s eyes are slightly different.
As far as aligning objects in your frame without being able to “ see them “ in live view, the best way I’ve found is to look for a recoginisable pattern in the stars and align that where you want it in your frame. Then take a quick shot. You can crank the iso up for this shot because it’s a test and it’s quality doesn’t matter that much as long as you can see the object. That way your test image doesn’t need to be very long. Once you have it framed where you want it, then take the iso back down to a good noise vs signal iso. This maybe 800 or 1600 depending on your camera. People will chime in here and tell you what “ sweet spot “ your camera is. This can be used as a starting point.
Hope this helps
Cheers

Thanks, Ryan, sounds like solid advice mate
I don't have a bahtinov mask yet, though i did download a template for one this arvo, will get onto it.
Also, good tip on locating stuff in a frame with that high iso test shot, will do that in future.
Cheers!
