Hi Chris, Gary, Barry and Jared,
With my refractor (Takahashi FSQ 106N) the contribution of the refractive index of the glass is so much larger (and in the opposite direction) than the contribution of the aluminum tube that it amounts to a constant negative temperature coefficient. I have shown that for my refractor, see http://forum.mainsequencesoftware.com/uploads/db2508/original/2X/7/716c1d5c68cb93eba78b72fbe1054f59e0cc7c35.JPG
So I am quite confident, that temperature compensation in my case would work very well, if only the correct algorithm in SGP was utilized.
No, I am not upset because the fix is not yet accomplished - it is the complete absence of any reaction from the developers that bothered me. The arguments were simply ignored. That’s a pity, especially because the issue is obvious, the solution was given, and it would take a small effort to fix the problem. I don’t want to bitch, I (like others in this forum) am interested in the further development of SGP.
This forum is the only way to establish contact with the developers. I don’t know what to do but post again when I get no response.
Thank you for your response, that’s great and I appreciate it.
