Comments on: How imperative is it to store a Telescope near outside temperature? http://www.telescopebuyingguide.com/blog/how-imperative-is-it-to-store-a-telescope-near-outside-temperature/ Thu, 17 May 2012 20:26:01 +0000 http://wordpress.org/?v=2.7 hourly 1 By: Philip J http://www.telescopebuyingguide.com/blog/how-imperative-is-it-to-store-a-telescope-near-outside-temperature/comment-page-1/#comment-2543 Philip J Fri, 23 Apr 2010 21:44:57 +0000 http://www.telescopebuyingguide.com/blog/how-imperative-is-it-to-store-a-telescope-near-outside-temperature/#comment-2543 It is more important to maintain a constant temperature if you are doing long exposure photography. For direct viewing, you can keep adjusting focus as the optics change. If you have a problem with condensation, you might want to keep the telescope warm until you are ready to use it; also make a thermal blanket to slow the cooling off process. If you do a lot of winter astronomy, you might consider building a heated dome, or you could do your viewing remotely on video, like the pros do.<a href="http://www.cargearusa.com/srch/srch.php?q=acura"> Philip J</a> It is more important to maintain a constant temperature if you are doing long exposure photography.

Temperature changes temporarily warp the optics and cause air currents that blur the image. But when the telescope settles down to the same temperature as its surroundings it goes back to peak performance. If you plan to observer on a cold night, take the telescope outside a couple hours before you plan to start using it to allow it to cool off and it should perform well.<a href="http://www.promusicmall.com/acoustic-drums-12832"> campbelp2002</a> I telescope that is either warming up or cooling off is not performing at its peak optical capability.

Keep the scope in a dry area if you bring it from warm moist air to a cool place. Depending upon type of telescope (reflector, refractor), its size (over 6 inch) and ventilation of tube, you should try to cool the scope for an hour before observing during winter. Heat currents and distortion of optics would make images poor. Never heard of optics walking out of position due to temperature changes.<a href="http://www.freshfacecare.com/524"> Starrysky</a> Condensation on surfaces is the biggest problem.

If there's a substantial temperature differential, you will get condensation going from the cooler to the warmer environment. If the temperature change is extreme, you may actually have the mirror or objective crack: that happens occasionally up here in Canada.<a href="http://www.bigjobtools.com/srch/srch.php?q=Delta"> Geoff G</a> Ideally, telescopes should be stored close to the nighttime temperature.

The reason one stores a telescope at outside temperatures is so that thermal changes don't damage the optics. Warm inside and then cold outside (winter) will cause the parts to expand and contract and possibly put the optics out of alignment. If you are not going to use it in the winter, you can store it in the house. In summer time, the difference in temperature outside and inside is not as great as winter. Hope this helps.<a href="http://www.besthomeorganizers.com/784"> jdomanico</a> The telescope does not need to be stored at outside temperatures during seasons that you do not use it.
