Tom,

Thanks! I look forward to re-doing this area with the STL and see how I can improve on it.

Mike,

You're 100% right. This is one of those ones that does need diffraction spikes. This wasn't actually my intended object that night, and, therefore, I didn't bother with the cotton thread. Perhaps next time.

Top work H.

Marc,

This was one of those images where I used the Bahtinov Mask and focused on a blue star. The Bat Grabber software told me that I was in focus, but, I was getting really bad blue halos around the bright stars of the cluster. So, after the first sub-exposure, I dialed the focuser back just a fraction and I minimised the haloing. It's still there, but, not as evident as it was in the single exposure.

David,

Yeah, darn annoying corners on the full frame. And, darn focuser sag. And, darn non-orthogonality!

I was very close to buying the Hotech camera adapter system, and, would have also got the field flattener as well, but, alas.

The 5D Mark II is being used for my other stuff, it's the STL-11000M that's sitting quietly waiting to eat stars.

You'll soon see what my new scope will be. Suffices to say, I won't have to worry about corners anymore!

Maybe if you kept the scope a tad longer you could have used something like the Hotech field Flattener, I found it to be brilliant to get rid of that feature in my shots.

So your scopeless, and stuck with a canon5D - whats your next scope?

Rolf,

Thanks, sir! Just makes you wonder how many of those billions of pin-pricks could potentially harbour sentient life? Thanks!

Thanks, all.
