Cumbrianwolf Posted January 2 Share Posted January 2 I am looking at one of the large dew bands with integrated controller via RVO for my Maksutov Newtonian telescope and as we know this type of OTA has a front lens element fitted and will be prone to dew so it will need of some dew protection. My question is will the heater band be more than enough as in I won't need a shield as well as the aforementioned? Thanks in advance. I have not dealt with anything that has glass on the front since the days of my first true astronomical telescope in the form of the Meade LXD75 Schmidt Newtonian and at that point it was visual only so a caravan hair dryer was the order of the day.

TerryMcK Posted January 2 Share Posted January 2 Most people use dew shields and dew bands on Mak/SGC/RASA type scopes to keep the corrector plate above the dew point. I’m sure I saw a combined shield cum heater somewhere recently. 1 Quote Link to comment Share on other sites More sharing options...

And I use one of these: https://www.firstlightoptics.com/dew-prevention/celestron-dew-heater-ring-for-sct.html But I don't know if they are made for the Maksutov Newtonian telescope Regards Graeme Edited January 3 by Graeme 1 Quote Link to comment Share on other sites More sharing options...
Cumbrianwolf Posted January 3 Author Share Posted January 3 Thanks I may opt for both as suggested. I can fashion a sheild myself and combine the band into it as well. Quote Link to comment Share on other sites More sharing options...

I bought what was thought the correct Bahtinov mask, and it is not anywhere near what I needed. I shall make my own dew shield to match the size and buy a heater band.

These work but I refuse to provide links to FLO. TSO's are more expensive but I enjoy denying FLO a sale. I even put them on my refractors. I think I've told you this before though. The stroke's turned my memory into Swiss cheese lol. 1 Quote Link to comment Share on other sites More sharing options...
William Shaw Posted January 4 Share Posted January 4 I'm very cautious and have shields as well as heaters on all my gear. I've had extensions printed for my guide scope. Maybe OTT, but I've sometimes lost power to my dew straps and might also have some awkward light sources and the extra shielding helps. The shields can buy some extra time. 1 Quote Link to comment Share on other sites More sharing options...
