Great video and important topic for sure. Temps about to dip below zero here in New England tonight so the dew heaters are making first debut of the season. Amazing scopes those FSQ’s on my wish list. First light tonight for my WO FLT 91.
Very cool, congrats on the flt 91!!!
This has been helpful , also thank you for your help with learning more about the TEC 140. Always appreciate the insight of those who has had first hand experience with the equipment
Glad to help!
very good video iam sure this will help alot people out. I have observed in -25C i dont recall if they frosted up or not though.
Yeah frost or dew was not an issue on that below freezing night while I was up till about 12am. When I got up at 5am to put away the scope it was all frosted over!
@@AVTAstro ok i see ya maybe all night i could then see that happening
I have learned concerning dew, if an eyepiece dews up you can swing it in your hand (if you dare to do so) back and forth with the lens side forward and it will dry the dew off. Its like blowing cold air on the lens. I try to keep my eyepiece case with the lid down so the dew forms on the case and not on the interior. I place the cap back on my refractors when I enter the house.
Yes putting the dust cap on IF the optics are not already dewed up is a good idea. If they are its not!
Problem with dew it is possible to attract dust so make sure your drying area is clean. I live in the desert and not even my iced tea gets dew on it usually. Rainy season here is Summer, but it doesn't seem to get humid very often and even then it's like 50% and then it's gone. Suppose it goes over to Texas/Oklahoma and makes them wonder why it's humid when it hasn't rained for two months.
That is true about the dust. Thats what leaves dew spots.
THANKS VERY HELPFULL VIDEO
Glad it helped!!!

Poll: Dew strap on the OTA tube just below the extended dew shield, or on the extended Dew Shield itself in line with the lens cell? I'm getting varying opinions form club members. I'm new to the refractor game, just bought an SVX130T. Having it on the OTA tube just below the dew shield seems to make more sense because the idea is to warm the air inside the OTA, right? Coming over from an SCT, this is how I always positioned my dew strap. Of course, the corrector plate on an SCT is a lot thinner when compared to all that glass up front on the refractor. I'm not sure how well the heat transfer would be.
Here is my 2 cents: You want it on the tube itself behind the dew shield. Why? Because you're trying to slightly worm the lens itself. The lens is attached to the tube with the lens cell. If you have the strap on the dew shield you are worming the dew shield and then the air around it that will hopefully transfer to the lens. You don't want the air warm though as it will affect the image quality as well.
@@AVTAstro Yes, this is the exact philosophy of warming I use with an SCT, i.e. dew strap on the OTA. Some of my club buddies swear by the dew shield method on their refractors though. Whatever works for them I guess.
I don't deal with a ton of dew issues in N. California during the summer months anyway, so not a major concern. Majority of my imaging is done up in the Sierra's, which is pretty dry during the summer months.
Really this video had nothing to do with dew and frost. It was just an excuse to flex those sick Takahashi’s. 😉
Was it that obvious??? ;)
