Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Portable battery power (star tracker, asiair, guidescope)

Post by yyD70S »

Good day,

I am currently doing untracked/fixed tripod widefield astrophotography (a DSLR & camera lens) and would like to take the next step (up, hopefully).

I have an old star adventurer 2i (which I have not started to use) and would like I’ll be getting an asiair (a gift) to basically assist with polar alignment & plate solving (guiding will be a latter step). I was also gifted an “old” Celestron Powertank LT (12V, 3A).

I don’t drive (thus ruling out car batteries) but I do plan to travel overseas/outback (meet flight requirements for lithium batteries) for dark skies. I don’t think I’ll move upwards to full high focal length telescope & EQ mounts; I’ll be happy if in 2 years I can upgrade (max) to say the Redcat 51 coupled with the AM3 (still sticking to widefield) as age has caught up with me.

I don’t think the Celestron Powertank Lithium is up to it if I want to connect the 12V 3A to the ASIAIR while at the same time, have the ASIAIR power the AM3 harmonic mount (even if it may power the Star Adventurer 2i (not GTI)… trying to future proof so to speak).

Most (forum members) would recommend at least a 12V 10A; many suggested even higher on the AMP. Problem being, some suggested models (chins, telentcell) do not ship to Singapore… most batteries don’t ship overseas.

Need all the help I could get to proceed please. Many thanks in advance.
