Sky Sim Guide Camera Specifications

[Jerry Stern]

I have been successful with the latest version of Sky Sim with NINA and my Wave 150i mount. Being able to learn and test indoors during a terrible Winter is fantastic. With Sky Sim's artificial star library, and Sky Sim Alpaca camera, plate solving with ASTAP in NINA works very good and I was able to determine meridian limits at some extreme positions. Now I am moving on to PHD2 guiding with Sky Sim's Guide Camera Alpaca. PHD2 is so far having some struggle though with guiding using the Sky Sim artifical star catalog. Does anyone know what is the Guide camera's Pixel size, Focal length and/or Scale{"/pixel} ?? Also is there a setting to "cover' the Guide camera to let PHD2 make a dark library?

The guide camera is using just a copy of the camera image. The one artifical image created is used by both camera. So focal length and pixel size are indentical. Pixel size is communicated via Alpaca, focal length is not becuase Nina is not reading it.

To cover the telescope, select in tab Image source "No stars, cover telescope". I will add it to the instruction. See attached

OK, makes sense. NINA or PHD2 'thinks' the FL for Guide is 120mm so that must be the issue since the main Sky SIm camera FL=430mm.
