Hi Guys and Girls
,
Its been a while since i posted, and i hope you could help me out yet again.
Im looking at investing in some dew control gear, but im not sure exactly what i need.
Im looking at heating my 12-inch solid-tube GSO Dob, as well as possibly my eyepieces and Telrad finder, while the eyepiece and telrad heaters are pretty self-explainatory, i just have a few questions regarding the heating of the OTA / Primary.
- Would i need a dew heater band for my OTA, or would a dew shield work?? (or both??)... ive heard that shields only work with Cassegrains...
- What brands would you recommend, and are the different brand's parts interchangeable??... eg: a Kendrick band and a Dew-Not controller??
- Is it necessary to use a controller, or can the bands be hooked directly into the power source??
-
( stupid question alert ) Where exactly does the heater band go?? is it wrapped around the OTA down close to the primary??.. wrapped around the circumference of the primary its-self??.. or around the middle of the tube to radiate the heat evenly?? (ive also seen heaters that are glued onto the back of the primary mirror...would these be more effective??)
- Does the secondary need to be heated also??
Any help you can give would be hugely appreciated, thanks in advance
