This is a nice little group which, rather surprisingly, is not often imaged. While the galaxies are not big, they still reveal some detail. Technical information here https://www.astrobin.com/ktv8f5/?

Thanks for all the positive comments. Didier, about the colour and FOV. I certainly thought about pulling the colour back a little, but I decided that there was more immediate impact leaving it as it

I had some trouble processing this one. There are faint jets emanating from the galaxy and getting these to show up without blowing out the galaxy was tricky. Taken over the last new moon period. Imag

Thanks Konstantin. That figures. I’ll look into doing that.

Ok, I misread one of the later instructions and thought there were two battery connectors that had to be removed. I installed a new battery, but the data base refuses to point properly, so I still hav

So is the lithium battery connector just the white plug with the blue and yellow wires?

This is probably going to be a "doh" moment, but I am puzzled by the following line on P11 of the keypad maintenance manual "Unplug the lithium battery connector. Note the Real Time Clock (RTC ) Modul

I was finally able to emerge from travel restrictions and get to my dark sky site--as expected the clouds didn't cooperate but I managed to get a few hours. Image is here https://www.astrobin.com/06kr

Very sharp detail—a nice rendition of this object. BTW it is in Hydra (just barely) not Centaurus.

i haven't logged in here for quite some time and I have missed this interesting topic, Will the procedure work with an AP900? I have CP4. If the answer is "yes" then I'll work my way through the threa

This was taken at the last new moon period https://www.astrobin.com/8aalro/ IC 2631 is a blue reflection nebula in the far southern constellation of Chamaeleon. It surrounds a young T Tauri star HD973

Thanks Stuart and Rolando. Yes, PixInsight processing, Maxim acquisition.

I was going through my picture files--what else to do in these times--and I came across this one from 2018 which I hadn't finished processing. However, better late than never, so here it is https://ww

I have an AP900 Mount which has been in my observatory for quite a few years. Can someone point me to any necessary maintenance procedures I should be doing?

I was browsing through some of the AP support Files and came across this item https://astro-physics.info/tech_support/mounts/drift-alignment-ra-correction-method.pdf which is essentially a drift align
