I received my AT115EDT a few weeks ago and have been fiddling with it between clouds and snow. The first one I received had an issue but Astronomics shipped out a replacement that same day! Wow, talk about GREAT service!
The scope is exactly as described, excellent optics, great fit and finish.
My new camera is an ASI1600 w/ Chroma LRGB and 3nm Sii, Ha, and Oiii.
My guide rig is an AT65EDQ with an ASI224.
My mount is an iOptron CEM60 (non-EC) with which I am thrilled, always below 0.5 RMS.
iOptron internal iPolar for polar alignment.
Acquisition software is N.I.N.A. and I am always amazed at how robust it is. It can get wonky at times but I always run the nightly build so I can't blame the software.
PHD2 and iOptron Commander.
PI and PS for processing. This image was preprocessed in PI with the new WBPP with darks, flats and dark flats but no bias frames.
The image is about 3 hours of data, one in each channel.
The H channel has fairly good focus but the S and O are off. I have not had great luck with the autofocus in N.I.N.A. but I am sure that is user error/learning curve coupled with unsteady air whenever I have tried to measure and configure filter offsets.
My image train has some tilt in it and that is due to the fact that I am hanging the camera, EFW, and EAF off the 2" compression ring EP holder and not a more robust direct threaded connection to the focuser. My TSFlat2 from Teleskop Service requires 110mm of backfocus and that seriously messes with the ability to do a direct threaded couple. I love the flatness of the field it produces but I may end up going with the AT2FF as that only requires 55mm of backfocus and that will allow for a direct threaded connection to the focuser.
In any event this my first narrow band image EVER so I am stoked that I got anything that approximates what more experienced imagers produce.
