ASI130mm or ASI120mm for guiding only..

astroolly

Hi all,

Am in the market for a new guide cam, and have narrowed it down to the 2 I have listed in the title

My question is, which one is best for guiding only and that's what I want it for and not planetary imaging, is the bigger sensor of the 130mm better or the higher resolution of the 120mm, I see that the 130 now comes with a guide port also, but what is the banding and noise like on the 130mm compared to the 120mm, am trying to decide if it is worth paying the extra for the 120mm.

Regards

Olly

as we discussed in Yahoo group

ASI120MM is the best plantery and guiding camera because of its low noise and higher sensetivity than ASI130MM.

but ASI130MM can do this job good too
