Forums Telescopes Dismantling EQ6 Performance

That looks very hopeful. The EQ6 I have was pretty usable with a quite good PE, but was becoming more prone to nights where there were large spikes superimposed on the PE waveform – dirt in the RA worm I assume.

Interesting what you say about  CMOS. Is it that you need to take fresh darks every night and can’t rely on using a bias frame and long exposure dark to generate darks for arbitrary exposure lengths? CMOS certainly are having an impact these days and with CCD foundries closing round the world, we may not have any choice soon.

I must admit that, CMOS sensors like the QHY600 have nice looking specs – interesting to see how the spec and actuality compare.
