Jones-Emberson 1 (PK 164+31.1) from Feb 24/25 + 25/26 2022. Taken through a 10in SCT F6.3 OTA @ F5 using a Starizona .75X SCT reducer atop a CEM60. I used an Orion Star Shoot Pro V2 ( APSC 6MP OSC sensor) camera and 31 x 900sec subs for a total integration time of 465 minutes (7.75 hrs) It was guided via a ZWO OAG/ASI120MM mini guide camera using Astroart 8's Full Frame autoguiding. I used temperature controlled focusing in real time throughout the integrations. This OTA has an optical defect which causes the diffraction spike effect on brighter stars.

Acquired via platesolved assisted goto, guided, preprocessed and processed in Astroart 8. My only processing was DDP with a high pass filter. I cropped the image about 20% (having some issues with flat fielding).

The mount (and computer) is located in my RoR observatory and was remotely controlled from our house, via Chrome Remote Desktop.

NGC 2359 from Feb 25/26 2022. Taken through a 10in SCT @ F7 using a Starizona .63X SCT reducer atop a CEM120. I used an Orion Star Shoot Pro V1 ( APSC 6MP OSC sensor) camera and 7 x 1200sec subs for a total integration time of 140 minutes. It was guided via a ZWO OAG/ASI178MM guide camera using Astroart 8's Full Frame autoguiding. I used temperature controlled focusing in real time throughout the integrations.

Acquired via platesolved assisted goto, guided, preprocessed and processed in Astroart 8. I used DDP, and 20 interations of LR deconvolution. I cropped the image slightly (having some issues with flat fielding).

Serpens Observatory is located in the Arizona Sky Village at 31.9°N 109.1°W (Elev. 4508 ft/1350m)
