I just bought a used Meade LX200 EMC 8" OTA which was deforked. I put a dovetail bar on it for use on my CG5.
I'm using my Mallincam Xtreme exclusively these days. When using it with the C11 the mount tracks beautifully as evidenced by the first snapshot below taken last night (80 second integration).
However, on all 3 nights I've tried to use the Meade, I can only get integrations of 30 seconds or less. The mount acts like it's not tracking at all, I have to keep readjusting the image to stay centered in the FOV (see second snapshot below, 56 second integration, taken tonight).
I have checked the balance over and over and it's excellent. Leveling is perfect. I do everything exactly the same every night whether using the 8" or 11", including my alignment procedure. One night I use the 11" and everything works perfectly, the next night I use the 8" and it has the same tracking issue.
I'm hoping this is something obvious to someone...any suggestions?
