Re: Best camera / ISO for astro ...


Hmm, interesting. It\'s news to me that higher ISO gains than base produce less noise. While I haven\'t tested this directly and exhaustively it\'s contrary to all of my ancillary findings - on µ4/3 bodies.

I\'ll have to prove it to myself in order to believe this. Yeah, yeah, I know, stubborn Doubting-Thomas me.

Most of the stacking I\'ve tried and that I\'ve seen on-line that produced any decent results were exposures of between 5min. and 40min. Usually 5 or 10 min. exposures with 20 to 40 exposures total. And of course all these require tracking!




BTW, a good tracking mount isn\'t all that much.

This Equatorial-Telescope-Mount plus this Dual-Axis-Motor-Drive for the same will get you primo motorization for a camera rig for around $350. Here\'s another (slightly less stable maybe) computerized with \"go to\" and tracking for $350 new: Celestron-NexStar-5-Computerized-Telescope-Mount. And another NEW one for $189 here: Celestron-Go-To-Computerized-Telescope-Mount.

I got my motorized GP2 mount with a 13cm reflector, and leg base, in 5-year old mint condition for $110 even. It works awesomely!
