1. Small problem. When your aligning your telescope and pick the star you want to use on the hand controller how do you which one it is when you look through the finder scope/eyepiece?. I've no problem picking finding the star visually. Any help appreciated.
Normally, the hand controller will use just the higher magnitude stars. Visually, it would be the brightest star in your field of view once it thinks it has it.
2. Also how do you get rid of dew on the corrector plate when you're observing. I left the scope last night for 10 minutes and when I came back it was covered in dew. I tried point the ota at the ground but this didn't appear to work.
10 minutes is not long enough. You should have perhaps put it outside at dusk, giving it plenty of time to acclimatise to the cold after coming from inside a warm environment. Also, on the coldest of night, power-assisted means are encouraged - hairdryer, dew heater (most recommended). You'll need either a main operated power supply, or a suitable charged up power pack (like the car starter packs).
3. When the telescope is adjusting to the temperature outside do you leave the covers on or off the finder scope/ota
Off, but not pointed upwards.
Hope this helps.
Seanie.
