7th December 2023: added payment option Alipay to purchase Astro Pixel Processor from China, Hong Kong, Macau, Taiwan, Korea, Japan and other countries where Alipay is used.
When I set up my club's remote scope, I forgot to schedule luminance flats. I do have a full set of RGB flats from the night but they are insufficient to eliminate what I assume are some condensation artefacts. Since the artefacts are very similar on the RGB filters, I assume they are on either the scope or the sensor.
If I integrate without the luminance frames, correction is very good. However, if I include the luminance frames, the resulting image shows the artefacts.
Is there a way I can use the RGB flats to calibrate the luminance frames or, synthesize a Luminance flat from the RGB flats?

Bump ... anyone have any thoughts?
In his video tutorial on this page David Colonnello shows how to make a synthetic luminance from RGB files.
