OK, I'm still not sure what power supply I should buy for my NexStar SE 6/8 mount. The onlybatterypacks.com products are out, because I cannot access their website. Are they out of business? Who knows? I really do not want to call them on the phone.
And I'm still not sure even what specs I should be looking for in a power supply. I don't want a mini-course in electronics, just a good idea of what I need for my NexStar. I'll only be using the power supply at home for grab-n-go sessions, maybe four hours max. I will continue to use my Orion Power Supply when I go to dark sites. Both at home and at remote sites I will have eight AA Alkaline batteries in the NexStar battery compartment as a backup.
