Dear All, [NOTE: this post has also been posted under Solar System Observing. As suggested by gstrumol, I double post it here in the hope the mods of the other forum will remove the post there.] First of all: I am new to this forum, and in fact, solar astronomy in general. Do not hesitate to tell me if I should place this question somewhere else. Any help/sug...

Hello! I have a Meade LX90 telescope with a controller that powers on, but the screen stays blank although lit. And pressing the keys doesn’t slew the motors or anything.

Older observer, but I don't use glasses when viewing. Prices are not far apart, FOVs close. The Ultra flat fields in mind are Celestron Ultima Edge & Sky Rover. I believe th...

I had a second 1 hour animation, which I wasnt able to babysit, so never realized tha...

At last Astronomical Twilight has arrived, -12° but not -13° yet here 63° North. 1.8 sec x 2337 = 1 hour and 11 minutes. FWHM of the raw stack is 2.20” arc seconds. That is the lowest value on a stacked galaxy image for me. I know that is a standard value for many imagers but in the rough terrain here under the jet stream it’s not bad, and my Omegon ...
