Re: Low-cost tracker design plans

Hi Karl. Back in the day, this was a lot of fun. Looking at your site, I think you would be disappointed with the results. Besides, there are better designs out there. Basically, I wanted to passively eliminate as much tangent error as possible apart from more complicated approaches. It worked quite...

Re: Best Stacking Program for StarTools?

Siril, while a little manual has been excellent. I've used Pixinsight, DSS, APP and others and never really liked them. Siril is fast, but it requires a basic knowledge of the calibration sequence and how to create master frames and apply them to your lights. There are advanced features, and it does...

Re: Help with starless image

Thanks Jochen. That is valuable insight. I have spent hours on this image at various times. And now that you mention it, there is perhaps a workaround with the present data. I'll report back, eventually.

Re: Help with starless image

I think this is a more sensible result with the stars pushed back. Widefield starless images are beyond my skills atm. The nebula is not overwhelmed, and the result is more natural without the distortion of star fields as in previous efforts.

Re: Help with starless image

Hi Ivo. Yes, it's been a while, and things seem busier on the forum with lots of great images. Too many to comment on them all. ST keeps getting better. Great work. Unfortunately, I can't devote time to imaging and processing as before, but I am determined to give the starless image a go. It's proba...

Re: Help with starless image

Hi Jochen. Thank you. It's a tough one. But improvement with the "must be darker than new" setting, Yes and 99%. Still not enough to be happy with the result. It would be ideal to mask the grey left by the stars but I can't get a mask to do that automatically and there are thousands upon thousands o...

Help with starless image

Hi. If anyone is happy to help? I have followed the unofficial starless instructions to a point- v1.8. This is the Heal result after blob masking many stars with halos. I've tried various masks, but how do I remove the grey spots left by the stars. It probably has something to do with mask settings,...

Re: Random crashes (version 1.4.352)

Occasional crash in 1.4, seldom 1.3. Usually a large file and some processes or ran out of space on root partition.

xubuntu 18.04 LTS 8mb RAM 4 core i5. No problems so far with 1.5.

Re: Utility to replay StarTools sessions

mono seems to be a preferred option with VB.NET or C# in Linux. A project to watch with interest. mono did not install well on my xubuntu system even with the ubuntu supplied packages.
