paul Posted September 29, 2021 Share Posted September 29, 2021 Just had a DHL notification that the factory have shipped my RA and DEC controller replacement boards and they should arrive next week🎉. I'm hopeful this will address the elongation of stars in RA that I have at 1200mm. This elongation halves my resolution in RA and extends the exposure time I need for good S/N. My mount is relatively old (! but only built Q3/Q4 last year) and has early revision boards. Newer builds apparently solved this issue for long focal lengths and I really don't want to do OAG if I can avoid it! Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted September 29, 2021 Share Posted September 29, 2021 Interesting to see if it solves the problem Paul. The CEM70 is on my shopping list. Quote Link to comment Share on other sites More sharing options...
