ASI 034MC Colour Webcam For Guiding?

[JohnSadlerAstro]

Hi,

This summer I am planning on upgrading to Auto-Guiding for my 130P-DS on EQ5. I am using a Skywatcher 50mm Finder as Guidescope to keep weight down. Will the colour version of the ASI 034 work ok with this setup, or will I have to get the monochrome one? I still enjoy doing some planetary imaging, and the ASI cam has a smaller sensor giving me decent zoom for the first time; it would be cool if I could get the pictures in colour.

Colour will be fine, but mono will be a bit better due to better sensitivity..... I used an old Meade DSI colour for a while and worked really well..

Definitely go for a mono camera as already said they are much more sensitive and if the main use is guiding then it's what you need.

I use an Orion 50mm Guide scope with an ASI185MC for guiding as I also wanted an ASI cam for planetary imaging. I used to use a Phillips Toucam for guiding ... never had any issue with either of them

Is the sensitivity argument about finding a star or having better guiding once the star is acquired ? The orion guide scope is open at f/3.2, I've always been able to get a star in the FOV of my guidescope.

MI have an ASI 120MC (colour) and a test with PHD and my guidescope at random gave me about ten potential guide stars with a 0.5 - 1 second exposure.
