<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I recently got a very late christmas present that turned out to be a telescope. I have an idea of where i want to keep it when im not using it, but the room in the winter time gets very cold. Probably as cold as it is outside (like right now its probably 20 F in the room and during the summer it can get up to 80-90 F easy on hot days. Are temperatures like these bad? We rarly use the room so temperatures probably won't be changing super fast during the course of the day. Its just that the room goes from one extreme to the other during the course of a year. <br />Posted by symbolite</DIV><br /><br />My advice (I'm not an expert) is that the room is fine for winter. It won't hurt the scope, and the idea is to keep the scope as close to ambient temperature as possible so you don't have to wait as long for it to cool. In the summer, I would probably not leave it in that room because once you take it outside at night it will take hours for it to cool enough for optimum perfomance.</p><p>What Kind of scope is it, BTW? I mean what style. A refractor, a dobsonian reflector, a closed tube reflector? That might also make a bit of difference.</p><p> </p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.
