My scope, mount and accessories are here so now my thoughts turn back to suitable filters.
Are these suitable to get started in CMOS photometry. Does anyone in BAA have experience of using them?
I wondered because they are cheaper than other makes(but still eye-wateringly expensive)

Hi Kevin,
Yes, I use these filters, but I only use the R, V and B. I would forget ‘U’, but the ‘I’ can be useful. I use them with a CCD camera, but no problems with a CMOS camera.
As well as photometry, I also use them for colour imaging as there is not enough room in my 7-pos filter wheel for a standard set of RGB filters. I have the following filters: L, R, V, B, Ha, OIII, SII, and this works very well for everything.
Best Regards
Ian.
