Re: DSS setting
ASTAP is multiplatform and there is a Windows binary here:

At the very top click on the "ASTAP Installer" link under "MS Windows 64 bit"

Re: DSS setting
I have completely stopped using DSS. I'm not sure if it's just because it's in a state of flux, but it seems completely incapable of correctly calibrating my images. I have now moved entirely to ASTAP (The Astrometic STAcking Program) for stacking -- you can get it for free from http://www.hnsky.org...

Re: Can't seem to get the colours right
Oh wow. That's with my data? That's an incredibly beautiful image!
I really don't follow your processing steps, I think I'm going to have to go through slowly bit by bit and understand exactly what you did to make it look like that. Thank you so much for working with my data

Re: Flats & noise propagation; who's up for an experiment?
Oh, my apologies. I am using different stacking software (DSS was having horrible trouble with my calibration frames). So I moved to ASTAP a few days ago, and it's superb. One of the only real problems with it is that it didn't align frames for composition -- it can merge three separate frames into ...

Re: Can't seem to get the colours right
Magenta stars are a typical feature of a SHO image. Some people layer in RGB stars, others desaturate the stars, some just leave them in. A quick and easy way to desaturate them, is to put them into a mask, launch the Filter module, set Filter Mod to Fringe Killer and then keep clicking on any mage...

Re: Can't seem to get the colours right
Ok so that's "sort of" my problem. When I get the DSO looking right, the stars are all wrong -- and vice versa. In your example the stars are very red! I guess that kind of makes sense, because the image is made up out of the same colours being representing the Ha, Oiii and Sii channels, and there's...

Can't seem to get the colours right
Hi there, So I have some data -- there's not a lot of it, a total of 9x300s Ha and Oiii and 6x300s of Sii, but enough nebulosity visible for me to combine it in a hubble-esque pallet in other software. However I can't seem to get it right in StarTools! I like the framing of the two nebula and want t...
