Excellent imaging run last night. Rho Ophiuchi Nebula / IC 4604 area
Success on twenty 10 minute exposures at full frame. 200 minutes of data.
No wind, seeing was excellent, temperature started at 14’C and cooled to 9.5’C.
SE Arizona, USA at 4725 feet elevation.
Astrophotography is really fun when all the parts of the kit just work !!!
Redcat 61 telescope - 300mm focal length, f/4.9 with ZWO EAF
ASI-6200MC color camera
AM5 mount - 3 years old original model
AM5 pier on a steel tripod with 2-inch diameter legs.
32GB ASIAIR with latest FW/SW, 128GB USB thumb drive on USB3 port.
200mm f/4 guide-scope with ASI-290MM guide camera
Polar alignment was completed using the ASIAir. Took about 10 minutes.
Guide calibration worked fine and guiding was 0.35 to 0.75 arc-secs all night, dithering worked every 2 frames, no issues with guiding and calibration. Guiding settled within 2-3 seconds after each dither.
Auto run worked and the ASIAir downloaded each full frame image with no issues, saving to USB thumb drive on the ASIAir. Auto focus was used at the start and then every five frames, all worked fine.
Seeing was excellent last night with 1.65 FWHM stars.
Meridian flip worked as expected and the guiding re-calibrated successfully on the other side of the pier.
The auto-run continued without any user input. I have not seen the meridian flip sequence reliably work in months but last night it was perfect. I would trust this to be unattended in the future.
It has been a long road ZWO… I have three ASIAIR plus, and one ASIAIR Pro so I have been part of the collective for several years. I can say the latest ASIAIR Firmware / Software releases are stable and worked without issues when using all ZWO equipment.
Thank You for all the hard work.
