Guide Cams

Hi all, just quick post about guide cameras, I was thinking of getting a QH5Y-II or the QH5YL-II wondering if anyone has a preference for which mite be the better of the 2, ive a limited budget hence choosing one of these, also as its for guiding purposes does it matter wether its mono or colour ? help appreciated. regards john

There's a spec comparison between the two on QHYCCD website (http://qhyccd.com/en/left/page3/qhy5-ii-series/)

A quick search on a well known auction site reveals a QH5YL-II Mono for £150.

I think most guiding is done in Mono.

Mono is the preferred route. I have an original QHY5 which I use for guiding with no problem.

I've recently bought the qhy5-II and don't have any probs with it guiding on the finderscope. i'd imagine on a guide scope it would be great. I chose the mono for the greater sensitivity although I've heard the colour is fine also

If it works, it works nicely:

Although the setup must be balanced, free from shakes or stronger wind buffets etc. (and aligned more or less).

The 5L is supposed to be more sensitive than the 5 (comparing mono with mono), I believe. I chose the 5L because I wanted to use it in a finder-guider setup and gambled on the increased sensitivity potentially offering me a better choice of guide stars.

thanks guys for you replys

this has helped me decide, im gunna go with the 5L as will be for guide cam throught a 50 finder to keep the weight down also as youve said its slightly more sensitive which i think ill need as can get a bit of light pollution not overly aggresive by near heathrow an its like christmas some nites from the glow

i tried an QH5 at light polluted Athens, and i was not very pleased with the results....

A DSI is very sensitive (even the coloured one), and never left me without a suitable guiding star.

( i use OAG, but i think that the point is the same)
