Re: Zwo 183mc Pro [cooled] - lenses?
I had a go at doing this with the following Astro Essentials Canon to T2 adaptor. See: https://www.firstlightoptics.com/adapters/astro-essentials-canon-ef-lens-to-t2-adapter-for-cmosccd-cameras.html I brought it to mount a Sigma wide angle lens for meteorite capture. Unlike standard Canon lenses the...

Re: Noise Reduction in Deep Sky Images
Incidentally GREYCstoration within Nebulosity works well. However, it is a lot slower than Neat especially if you up the number of iterations and the computation precision.
I understand it is now a GIMP and Photoshop plugin.

Just tried creating a profile from the dark frame taken whilst imaging NGC1893 (lots of stars and nebulosity). Cleaned up fairly well. Probably not the way to go but worth a punt.

Re: Noise Reduction in Deep Sky Images
I have had good results with this on DSOs where there is a large enough area to place the sample box that has no image i.e. galaxies, clusters and so on. Where it will fall down is when the whole frame is image i.e. nebula and star fields. I have not tried this but I guess if you took a single frame...

Re: Sharpcap and Sequence Generator Pro
Robin, many thanks for this. Yes, I did mean 0.5C. I had not come across circle of confusion (though given the above, it is no doubt a space I inhabit). I have trawled the internet and now understand what it is however, I am at a loss to understand how you came to determine the values you suggest. I...

Re: Sharpcap and Sequence Generator Pro
One question that does not seem to be addressed is what is the achievable resolution of a single focuser step if the OTA system is subject to a temperature change? Aluminium has probably the worst coefficient of thermal expansion of common OTA materials. So if we assume, for example, the gap from th...
