No, it just stops the excess.

Cooling a scope down only to heat it up again seems most illogical. An alternative is to stop the heat exchange process by blocking the radiation. Once your scope has cooled sufficiently, wrap it in insulation. This will stop the tube radiating heat. The effects will be two fold: firstly, for an SCT, the lack of tube radiation will have a similar effect on the corrector plate if combined with a long dew shield; secondly the lack of radiation will stabilise tube currents and reduce seeing issues. Aluminium bubble wrap is very inexpensive and can easily be layered and cut as a wrap-around connected by velcro.

Hi Tony. welcome to SGL

I would be interested but it is always below the line of the houses here. Never had a scope on it.

Hi, welcome to SGL

Hi Andy, welcome to SGL

See you on the flip side I'm sure a lot of people here don't see what goes into running SGL and all the work you put into it. So a big thank you from me and everyone else for doing a fantastic job ?

Seems the future isn't what it used to be

Nothing exists until you observe it

I am from 300 years in the future. Unfortunately, my time machine won't be invented for another 300 years, so, I'm stuck here...

There's nothing I'd like better than a huge Dob. Sadly the LP here is so bad it would be a complete waste. This is why I stick to planets and have my trusty C9.25.

Great images. Welcome to SGL
