You'll love the Esprit 120, great scope. I bought the red/flattener for it too, going to f5.4 does make a lot of difference to signal although I've only used it once or twice. Not enough time to image at the native FL let alone when reduced. |
Cheers, Craig. It's a very dim target. Next time I'll go after Omega Centauri
I'm looking forward to that 120 for sure!

Just draw a region of interest ROI around your object , and resize it in and out and using the ignore fine detail slider between 1.8 and say 5 pixels , you will see the changes in detail and brightness as you fiddle around a bit . Try adjusting Shadow Linearity up from default 50 to say 60 or 70 ??
It takes time but your images will benefit more from AutoDev ( Film Dev is “ the easy way out” for stretching your image but is restricted or limited what it can do ) Just go on the Startools website and read up about AutoDev and Film Dev . I think you will benefit greatly.
AutoDev is the better option in most cases unless you have crap data or limited data

Thanks Martin. The trouble I have with AutoDev is that it does this to my images, even with various tweaks. It turns everything (including the first go of this Lobster picture) into a hot noisy mess. I've sought help from the StarTools forum and no one seems to be able to tell me why, but FilmDev is something that actually works for me so I'll stick with it.
