QHY5 guide cam question
« on: 07:19:27, 07 August, 2018 »
Hi, i have been away from the hobby for a few years now, but recently have rekindled the fire once more.
I live in Australia and want to build up some astrophotography gear up.
Nothing outrageous and i want to take my time as funds are very limited.
My question is, i have an opportunity to buy a QHY5 guide camera and wondered if they are still a viable, usable camera these days? as tyere seem to be cameras aplenty to pick from.
I can purchase it for around the $115 mark, which is about 65 quid.
Would this be a good buy? also can it be used for imaging as well?
Many thanks folks
All the best
Tony

I have guided with a QHY5 on a small guide scope quite successfully. Not the most sensitive of guide cameras so a relatively fast guide scope would be good. 65 quid sounds a bit pricey though given how old they are.

I've used a QHY5-II on an ST80 guidescope for the last few years without any problems.  There has always been a usable guide star in the image without ever exceeding 4 seconds exposure.
You'll need an extender tube for this setup.  I have mine mounted directly to the tube rings of the main scope, so flexure has never been a problem either.

I might remember wrong but were there some driver issues with original QHY5 - with Win10 ?
ASI120-S might be a bit more modern alternative, and not that expensive.

I've remembered that my first QHY5-II had to exchanged because it would not stay connected to the USB.  As far as I know I don't think that this was a general problem though.
I must admit that I would probably get the ASI120-S now.  In the UK its a fraction of the price of the QHY5-II mono.

I am still using my QHY5 that I bought in 2011, never had any problems with it.
