  1. Do you know if it'll reduce the red halos I get round stars with my modded Canon? Is there any way I could use this with my Canon? I normally use a clip-in filter.

    That makes so much sense! Thank you.

    Which CLS Filter?

    Hi all, which CLS filter would be best? I get nasty red rings around the stars with my modded Canon and wondered if one of these would stop that. https://www.rothervalleyoptics.co.uk/astronomik-cls-ccd-deep-sky-light-pollution-filter-canon-eos-clip-fit.html https://www.tringastro.co.uk/skytech-cls-ccd-canon-eos-clip-filter-12845-p.asp Alexxx

    Please Explain Debayering

    Thanks James. I'm not sure if it is USB3 to be honest. Will have to check. But why is it called DEbayering?

    Thank you!
  7. I have an ASI120MC cam and prefer to capture in RGB with SharpCap. It defaults to RAW and I ended up capturing in that setting today. The vid is monochrome and covered in dots (Bayer?). I read in the manual that the image needs to be debayered, which Autostakkert can do. So, the CMOS chip has a Bayer pattern, so why debayer? Is it better to capture in RAW or RGB? and what's the difference? And as an aside, I can rarely get above 22fps using USB3 with my laptop. Any idea why it isn't faster? I know that increasing the Saturation slows the frame rate down which is why I try to keep it as low as possible. Thank you! Alexxx

    Flats Advice?

    That's excellent! Very many thanks. I've saved this to Favourites.

    Flats Advice?

    Thank you! I did need that, but I meant how you put the light box together!

    Flats Advice?

    I'd like to see your work flow. I can't picture the light attachment!

    Flats Advice?

    Great! Many thanks.

    Flats Advice?

    Thanks Mark, but my kit isn't set up still. I couldn't reproduce the optic train setting. What light source do you recommend? I did an artificial flat using this tutorial!
  13. I've always been rather daunted by trying flats with all the myriad advice on how to create a light source, some being quite techie for me! I want to take flats with my 72mm frac. Can someone suggest a simple flats technique? Alexxx
  14. I've tried processing with FITS and I never get a good image.
