All the best.
Thanks Lester. Its going to take a lot of time processing it all.

I still can't get over how much gear you have and have had and while it's top notch stuff, I keep looking at your stars..
This image for instance appears flat and the stars look slightly out of focus giving a soft blobby look. This I've noticed on many of your images.

I've done probably 250 images. Focus is obviously a key point but not sure "many" is accurate. FSQ and especially with the reducer the CFZ is small and it shifts with temperature. I do need to fit a Robofocus to it to help with refocus as it is difficult with the 106ED focus lock. My other scopes have robofocus and the only way the focus would be off would be temp shift throughout the night or very slight focus differences between the filters. I do use the same focus for all LRGB an perhaps there is a slight gain by focusing for each colour and setting that up to be done by software but I think it is a pretty minor game. Seeing would play a bigger role there.

I think maybe your should take a bit more care with focus. With the FSQ you should be able to get pin point stars, resolving well down to even the fainter magnitudes. With 2 hours worth of data and such a fast F ratio, this should be well the case here.
If you're finding focus a prob, then perhaps a better dark site or pick the nights.
This is all imo btw, but I only say it as I see it.
I really feel your letting yourself and your great gear down.

That's a bit insulting isn't it? and out of character for this site.
