I should have read your post more carefully. I was using a small mak at 1250fl. If you were using a 200mm camera lens then it would be perfect for that. I apologise.
I was able to make ~30 sec integrations with the ioptron mount at 1250mm. The mount does trak quite well at high magnifications but you must set it up level for it to be reasonable.
