Re: Platesolve is wrong?

If you take 52 Cygni (in the Cygnus loop) as a reference star, since it is in the region you were looking at, its J2000 coordinates (according to SkySafari) is: RA = 20h 46m 30s, DEC = +30º 47' 39.9" Again, according to SkySafari (with nutation and precession), JNOW (right at this moment :-) is RA =...

Re: Cannot create a bootable SSD

>> I really want to have a backup that works! what are my alternatives? Did you try to low-level reformat the card using the program that the SD Card organization provides? https://www.sdcard.org/downloads/formatter/ If that still does not work, try the microSD card that ZWO recommends (it is not an...

Re: Feature Requests?

>> 1. Focus - Measure HFR across whole image, not for an individual star. I had sent this suggestion to ZWO some time ago when they started discussing autofocusing in ASIAIR. But it should work well even for manual focusing, as you mentioned. It should work really works well when seeing is poor. By ...

Re: 6200MM Saving Image Download Speeds

2.4 GHz WiFI limits your downloads to 300 Mbits/sec. An AC750-class (for example, the TP-Link Travel Router) extender has a limit of 433 Mb/sec transfer speed on 5 GHz, so it is only marginally faster than using 2.4 GHz. For higher speeds, you need faster routers e.g., the AC1200,- and AC1500- class...

Re: ASIAir not driving EQ6-R pro mount correctly

I don't think you are doing anything wrong; I have read plenty of reports of the same behavior (not moving at all, or moving well past the 60º) while the ASIAIR performs polar alignment. The maths right close the spherical coordinate's pole is very prone to numerical error. So much so that I always ...

Re: Pentax DSLRs?

Instead of swapping the camera physically, you can also switch the ASIAIR "Main Camera" to use your guide camera and guide scope to perform the polar alignment. When you are done with polar alignment, switch your guide camera back as the ASIAIR's "guide camera." If your guide scope is aligned with y...

Re: ROI and ASIAIR Pro

>> ROI function is available only for full frame cameras. That is how I too interpret the update notes for v1.4.4. ZWO probably implemented ROI for the full frame cameras because downloads of full frames through WiFi can take a lot of time, not to mention the memory usage and scaling the image for t...

Re: Auto guiding problem ASIair Pro

The Gain slider for the Main camera is in the Main Camera Settings window. The Gain slider for the Guide camera is in the Guide Settings window. I have been guiding for almost a year now with the ASI290MM-mini, using either a Borg 36ED or Borg 50-mini as the guide scope. It has never failed me yet (...

Re: Safe shutdown

For something that is so rarely used through the night, it probably does not justify a quick access from a Main menu button. One level in is fine, as long as its location is intuitive and documented. Perhaps a "Soft shutdown" item by itself in the Settings window, instead of lumping it together with...

Re: Never ending Daylight Saving Time Issues

Short one-line answer: turn OFF any Daylight Saving Time flag on your handset, and make sure the UTC offset on the handset corresponds to your UTC Offset in Winter. On my Korean RST-135 mount (which also does not have any idea of Daylight Saving Time either -- it is a western thing), simply setting ...
