My Mak 150 has a rattle in the OTA, It's actually a nut from the focuser shoe holding bolt. Don't ask me how this happened, just to say it was an embarrasing operator error.
So now I need to get inside the OTA and refit the focuser shoe. Anyone advise the best way to get into the OTA. Should I remove the front of the scope or enter from the primary mirror end. If so is there anything I should be aware of ie miss alignment of fittings etc on replacing the fittings would it be a difficult diy job or do I need professional help. Thanks for reading.
