Official StarTools support forum

OK, thanks Burley. "No White Balance" in my first stack was what precipitated this post, so I'll load that one again and try the white sample as you describe. I think I tried it once before, but ended up with coloured fringes on stars, so probably did not do the mask correctly. So, what do I use as ...

Quick update: In DSS, started to re-mark the comet to do a re-stack, and noticed the distinct green in the single camera images. So I checked the RAW/FITS/DDP settings, and it was checked "No White Balance Processing". If I check "Use Camera White Balance" then the green overdose goes away and the i...

I think I'm doing, mostly, the right things in ST...I'm using the second option to load, I'm cropping, and binning, and I'm noticing thoughout the development, contrast, and sharpening steps that the image has no colour. I'm sure there are other things I'm missing, or doing wrong in ST, and it's bee...

OK, went for the renewal. For 27 Canuckbucks, it's not even worth thinking about.

I understand, from reading the forum posts, too much green bias is not an uncommon problem, and ST has ways to deal with it, but I have not typically had images that are too green. Usually, it's the red peak that is furthest to the right, due to some slight light pollution. Last Saturday night, I im...

So, is the takeaway for wiping the colour data, that it should be even? (I.e., ugly, but evenly ugly)

Thanks Ivo! Yeah, renewal might be the best idea. I went ahead and installed the latest stable, and gave it a spin on M61+2020jfo, and hoo-boy! There's certainly something to be said for 8 [logical] cores and 32G ram compared to my old desktop, but that went WAY smoother than I seem to recall in the...

It's been a few years since I used StarTools, and in the intervening time, I've lost a hard drive, but I still have a few backups and my licence key (a file named "license" with no extension). Now I have a new astro laptop and want to install and start using it. The latest download I have is 1.3.5.2...

I made my flats on the dining room table. I have a laptop with a 17" screen, just large enough to cover the end of my 8" Newt. I set a pure white desktop, no icons, and a sheet of paper to help make it evenly lit. You could probably use the t-shirt method indoors as well if you can have a large even...

...I would have to redo flat everytime as the camera is never in the exact same spot between exposure nights :/ I set up and teardown every time. Maybe I'm not as fussy as you, but I only use two camera orientations...long dimension E-W and long dimension N-S. The only other camera requirement is t...
