I have been trying to troubleshoot excessive slew warnings (over 50%) when building models in APPM. From observing the Dec coordinate values in APPC I believe it is the Dec axis. Here is what I have d

Last time at a dark site no one was around, so there were no AP's, cell tethers, etc. Often there are MANY with all the apple-this, and asiair-that. So I was surprised to see the CP4 had opened an acc

Hey Astro-Nuts, We have another new video to share with you! If you’re using PHD2 for guiding with an AP encoder mount (Mach2GTO, 1100GTO-AE or 1600GTO-AE), this is for you. This tutorial covers basic

Hi, This one would be for Ray / Dale I guess. For an unknown reason tonight I get a "Invalid location for APPM settings file" when inserting the Dec Arc Model in the NINA advance sequencer (Astro-Phys

I was able to find only one amateur image of this galaxy, which is quite strange considering its size (4 arcminutes) and brightness (mag 10.6). I would have expected that its location in Virgo would h

I just upgraded the chip in the GTOCP3 from "J" version to "V2". Instructions say that I must reinitialize either via the hand controller or computer connection. How do I tell what version of firmware

Hi, I have two question /consideration that I'd like to be validated. In my former Paramount ME mount a sync issued by a sequencing software like NINA would result in a model corruption. I assume with

Im seeing a lot of flex and play in the Dec. axis under load. I noticed the dec axis is always very stiff, I figured this is how the new ones are. Tonight for the first time, after shining a flashligh

A local amateur took my image and looked it up for magnitudes. Faintest star recorded was 19.5, faintest galaxy recorded was 18.95

Wanted to see how faint I could go here at my light polluted industrial park. Local amateurs pointed out a tiny grouping of faint galaxies that they haven't been able to get much info on them or any d
