I've been into astronomy for decades, but I've just recently gotten into astrophotography. I have a Meade DS-16 that I bought from a nearby CN member a few years ago. It's a monster of a scope and mount, but the views are magnificent.
The issue that I've been having is tracking error with the mount. I'm limited to ~4 second shots, and even 4 seconds without star trails is pushing it. Does anyone else have experience with this scope/mount who can give me some advice on what I should be able to expect?
A few notes:
- I poured a concrete pier and I have the mount permanently fixed to the pier. I've eye-balled the polar alignment, but it's (obviously) not perfect.
- The control box that came with the mount seemed to be finicky and it was not tracking correctly at all, so I've removed that from the equation - I have the mount directly plugged into power.
- It is somewhat difficult to manually rotate the mount on the RA axis (it's even worse along the declination, but that's another topic), but maybe that's just due to the clutch friction and the inertia of this monster? I don't see any way to release the clutch, so I've just been rotating it as-is.
I'm not sure if my issues are polar alignment, a worn mount needing a rebuild/oiling, or if this is as good as I should be able to expect from this setup with an 1800mm FL.
