  1. I finally got to realize the full potential of my ASIAIR this past Tuesday might. It was a joy to work with, although I still have some settings to juggle on the phd program. I was able to get a couple of good captures. These are stacks of 150 second exposures at 135 gain on my ZWO294 uncooled. 12 frames on M1 and 5 frames on M82. I also used darks and bias, no flats.
  2. I had the same problem where I had done a two star alignment, imaged M31, then asked for M1. I was using the Synscan app on my computer. It told me M1 was out of range. I knew that was wrong, as it was directly overhead. I decided to ask for the Flame Nebula, which was clearly visible to my south. It then proceeded to point towards the ground. I just packed up at that point. Upon investigation I discovered I had south instead of north in the latitude coordinates. I have now finally discovered how to interface my ASIAIR with the mount after many times of trying unsuccessfully. The Synscan handbox is not even in the equation anymore. I hook the ASIAIR straight to my EQ6R pro with a type 2 USB(hp printer cable) and the ASIAIR is fully functional. It gets it’s lat/lon coordinates from my ipad as well as the time and date. Now my life is so much simpler. I’m still waiting for a break in the weather to try out the onboard PHD, but from all indications it looks like I’m finally on the right path.
  3. One thing you need to know is that high ISO does not bring high noise. The lack of light brings the noise. With high ISO you are merely asking for a lot of light, not really getting it. The effect looks like more noise because there are pixels that don’t get enough light in the time that you ask for. You can either go with more integration frames to fill in those pixels or you use a lower ISO number. With the lower ISO number you must do a longer exposure to reach your goal. Bottom line is that if you are using short times because of star trailing you need to use higher ISO. If you are guiding, you can use the low ISO and fill in those pixels with light instead of getting digital noise. Of course, if you have light pollution creeping in, as do many of us, you will be overexposed with any long exposure not using narrowband filter.
  4. I would like to use my old Nikon f lenses with my uncooled ZWO294. What is the adapter called, or could someone send me a link to buy one?
  5. Thanks for the input guys. I called OPT and had a discussion with tech, and was going to try whatever he said, but he had nothing. I finally changed mount name from Synscan to EQ mod, and baud rate from 9600 to 115200. Plugged USB directly from ASIAIR to EQ6R pro without hand control. Everything works great, and I can’t wait for clear skies here in Savannah, Georgia.
  6. I have had an ASIAIR Pro for about 2 months now, and so far have not been able to control my Skywatcher EQ6R pro with it. I am using a 5th gen ipad, and have an uncooled ZWO294, and a ZWO120 mm guide camera. I have been successful using all of the main camera functions. I have been successful using the polar alignment function. After some plugging and unplugging and plugging in again, I have the ASIAIR say it is connected with the mount, and can see the control interface and object list, but no amount of button pushing will make it slew. The hand control on the mount says “both axis’s non responsive”. Somebody throw me a bone.🤪
