Hello All
Can anybody advise the best position for placing a
dew heater on a AP refractor.
At the "top" of the ota, just in
front of the dew shield
At the "bottom" of the dew shield, just
in front of the ota
Over the "band" containing the "collimation" screws
separating the dew shield from the ota
Hope above makes sense - appreciate any advice for
most effective placement.
Thanks
Eddie Guscott
