I have been enjoying using a computer to control my telescope, cameras, and my Orion Atlas mount. I recently took a stab at taking photographs of the ISS and have been using SkyTrack by Heaven Scape to stalk after satellites. Some of my early tries at using SkyTrack have involved lurking in the middle of the ISS track and waiting for it to pass thru. I have not been terribly successful, it appears that the my mount is often not positioned close enough to capture the ISS track within my 0.5 x 0.25 degree FOV. I have previously worked in ASCOM to provide several mount calibration points (a very slow and tedious process), and I use SharpCap to ensure I have good polar alignment. This is usually close enough to invoke plate solving to lock onto a target for DSO photography. However, with SkyTrack the mount itself needs to be pointed more accurately. What are my options for doing the tedious task of mapping out the sky and storing a calibration curve or model into the ASCOM files? I did see a program called MaxPoint which appears to do this. Will this work with SkyTrack, Stellatium, etc. to position my mount? Are there any other options to taking data and storing a calibration curve in an automated fashion, especially for portable, on-the-move operation? Appreciate your sagely advice and suggestions.
