This configuration is useful to reach a height of 76 °, which is very respectable if considers to the impassable limit of 80 ° in height altazimuth for photography. But back to the last test tonight. The test consisted in taking an automatic sequence of 60 frames of 1 minute each in order to calculate any possible angular change between frames. The test has a logical log.file who monitored the behavior of the Pyxis during the session. I pointed the telescope to NGC7160 that in the moment starting test had a height of 61 ° or so, I activated derotator and chosen a guide star in the AO-7, calibrated and turned on all the autosequence shooting. After the first image, I have changed some parameters to guide and immediately everything worked great. I downloaded 60 images of 1 minute each and between the first and last frames, the derotation field is virtually absent and the height of NGC7160 was 71 ° when I finished the test. The Pyxis has worked better than a Swiss watch, really amazing.
I should point out that my collaboration with Optec, in the development of this project is totally free from profit of any kind. My participation was and is dictated only by the immense love I have for this wonderful hobby, Especially for astroimaging altazimuth. I try to insert a small animated gif (if the server allows it!) Comprises the second and last frame of the test, therefore 59 minutes of difference between the two frames. The frames are completely raw, so no dark, flat, without any processing, just like Mom ST2000 has pulled out.
Currently the software is not available yet (still need to finish their latest test), but I think it will soon be made available to all and I'm sure that this will be a great package for photography altazimuth.
