Which cam should i buy?

[Sotein]

Hi Guys,

I want a cam for AUTOGUIDING but at the same tim use it for AP.

I had read a lot of threads about this... but not really sure about what cam choose...

This are the options:

- QHY5L II   COLOR

- QHY5L II   MONO

- ORION STARSHOOTER COLOR

- ORION STARSHOOTER MONO

i had read that the COLOR ones have some problems...

My scope is a 8" CELESTRON mounted in a CG5

thanks for any advise !!!

Do you mean "At the same time" or do you mean "Also" ?

If it is at the same time then I am not aware of anything that will both take an image and audio guide simultaneously.

There are the SBIG dual chip CCD s

U r right Ronin, i wanted to say ALSO. Any idea of which cam of those four use ?

The latest Orion Starshoot (all in one) cameras are basically the same as the QHY5L II so your choice is narrowed down even more.

Ooooh, I want a camera that does that: "left a bit, up a bit ... "

But back to cameras.

I'd go with a mono camera myself. Also, be aware there are basic differences in the requirements for cameras to either a/g or image. Guide cams only need to be able to take an image for a few seconds and mostly avoid the cost and complexity of cooling (tho' I saw somewhere that there's a cooled QHY5 on the way - and you can get a QHY6 that's got  Peltier in it - same with the Mammut). Whereas imaging cams are much more expensive due to the cooling and the higher quality, reduced noise electronics and using a more sensitve CCD sensor rather than a commercial grade CMOS one.

The best for guiding from that selection is the mono QHY5-II (or equivalent!) because it is the most sensitive. The problem with all these cameras for DSO imaging is that they are not cooled so tend to be noisy for long exposures. The colour QHY5L-II is a fine planetary camera though. Either will work as a guidecam but you are using an SCT then that works best with an OAG rather than discrete guidescope, and if you went with an OAG then you definitely want the most sensitive camera you can get due to the limited light and FOV via the OAG. If using a guidescope then either would be fine.

Hi, 

I use a QHY5L-ii colour for guiding with 9x50 finderscope. The sensitivity is very good. Works very well! This camera is also very nice as a planetary- and moon camera and the price quite low. The only reason I chose the colourversion was planetary imaging. 

I guess as mentioned before....buy a real cooled ccd for deepsky, that´s my goal in the future.
