Re: Flats & noise propagation; who's up for an experiment?
Hi Ivo, I'm not sure whether you're still interested in this data, but I have been concentrating recently on learning to collect clean data and good calibration frames and stacking properly, and I thought you might be interested this one set of stacks where I accidentally forgot to add flat frames ;...

Re: Save as 16bit greyscale tiff
DSS refuses to stack a 16bit Gray light against an RGB flat. I guess I could use StarTools and then convert somehow to Grayscale in say Gimp?admin wrote:StarTools' TIFF output is indeed always RGB no matter the color saturation. I wouldn't think that'd be an issue in DSS though?

Save as 16bit greyscale tiff
Help! So, I messed up when collecting data yesterday. I have a luminance stack which is binned 1x1, and Ha and Oiii stacks binned 2x2. Unfortunately, all of my my flats and darkflats are binned 1x1 -- I made a mistake in configuration, and forgot to bin the flats for the Ha and Oiii filters as 2x2. ...

Crescent Nebula NGC6888
Here is a photograph of the night sky that I took last night. The object in the centre is known as NGC6888, its name is the Crescent Nebula. The photo was taken from my home in Light-Polluted London. Exposure: • Total Exposure 1 hour • 15 x 120 seconds each of Ha, Oiii • 50 Flats through CLS filter ...

Re: The way to M31
Hi, I would also move the log file to a new name and let StarTools create a new one so to have a lighter file to examine. If you chose a naming convention you can archive your log files, this would let you retrieve the steps you performed for each image. This makes me think that it would be nice to...

Milky Way Processing
I'm currently on holiday, and most of the places we've visited so far have either had no night-time (Iceland -- there was seriously no darkness at all, not just no astronomical darkness but no actual darkness!), or have been bortle 9 light polluted (big cities like Boston, Halifax, Quebec City, Mont...

Re: Flats & noise propagation; who's up for an experiment?
My apologies for the radio silence. We left for our summer holiday on Friday evening, and it turns out I've had no time to do anything at all over the past four days, as we've been visiting Iceland. There was really fast internet in the hotels we stayed in (my son ran a speedtest and got synchronous...

Re: Flats & noise propagation; who's up for an experiment?
Aha! Yes, that makes sense, and yes I'm new to StarTools and tracking :-). The idea sounds good! When I get some time this evening, I will do my best to process the stacks correctly, and then I will upload what's needed. I'll also put the raw files out there in case you want to play with stacking th...
