Ancient History - NexStar 4GT

Nick Hudd All Messages By This Member #15427 I am looking, if possible, to update the software and firmware for a NexStar 4GT. This scope has been, in practice, on loan elsewhere for years. It was always, and still is, a very good instrument though recent electronic issues took two years to solve due to lack of available parts. Now it is back in this house, and working well, I am minded to attempt update of the firmware and software. However, Celestron have moved on by light years (this scope's last update was probably at least fifteen years ago, maybe more). Moreover, the chance that it will talk to my Windows 10 64 bit computer is questionable. However, I do have leads that will connect it to a USB port! Does anyone have advice, comments etc? (Which may include "Don't"!) There are files on the Celestron site but I am by no means sure which to try. Any feedback will be appreciated befor I try plugging it in. Nick Hudd
Joe Ulowetz All Messages By This Member #15428 I recently obtained a Celestron C11GPS from 2001. After trying and failing to get the old electronics to work, I replaced then with OnStep:??? This does require quite a bit of electronics and programming skill, but I finally have a nicely working telescope. -Joe

There are several websites with old firmware downloads but they are somewhat difficult to find. If you don’t have them, I can find them for you. ?

Nick Hudd All Messages By This Member #15431 Thank you to all who responded. I have decided the best answer is to leave well alone. Though old, the scope is functioning as well as it did and has always been a tremendous aid to showing the night sky to the uninitiated. It is quick, accurate, and, compared with my 8" can get wider field views, which all helps with the public relations! It is not sensible to enter unknown software territory. Thank you to you all Nick Hudd
