Official StarTools support forum

I thought this dso object should be reddish, am I wrong? Maybe these colors are due to the filters used?

Hi again Stefan, I've playing with your data, but I don't get a decent result. The stars have always a blue tone that cannot get rid of. I've tried both the compose module (with some doubts, by the way) and also loading the image as a normal fits file (second option). Could you please upload your be...

Thanks a lot for sharing your data, stephan. I've been struggling with the image and to be honest this is resulting very very confusing to me, mainly due to the lack of concepts I still have. There are a lot of terms that result very cryptic to me. I'm trying to find out the meaning of them but at l...

Hi,

Could anybody share a dataset (already stacked, if you wish) taken with an optolong l-enhance filter? Preferably with an unmodded dslr.
I'm waiting for one of this filter and in the meanwhile I would like to practice.

Thanks in advance..
Miguel

No darks not required all I do is every couple of months I take 50 bias frames , and in DSS or Siril during stacking I load the bias as darks , I was told to do that with dithering by a respected Astrophotographers on a local forum and seems to work ok so lights and flats on the night and saves tim...

Depending on your setup try dithering and do away with darks if possible i dither between frames and use APT connecting to mount via Eqmod basically the mount moves image approx 10pixels between subs does away for the need for darks and saves time and for dslr imaging is a better way more info here...

sorry guys, just seen this post: viewtopic.php?f=10&t=1841
I'll have a look

Hi all, This is a (I think) quick question. I'm still quite confused how to open a fits file within startools: "Linear", "Linear, from OSC/DSLR with Bayer matrix and not white balanced", and "Non-linear sRGB source". My first thought was to choose the second option. My fits file are raw files (DSLR)...

Hi, Thanks to both and sorry for the late reply. I've been doing some tests. I've started from scratch, with an ambient temperature of 24C degree, and the camera idle and "cold", at ambient temperature. Then, I've been taking photos consecutively with an exposition of 5 minutes, during 2 hours; and ...

Hi all! I've been reading about calibration frames and now I'm dealing with darks. I'm trying to build a darks library with different iso and temperature parameters. I've read that temperature is an important parameter. Temperature at which lights were taken has to match with darks ones, right? I al...
