CoolBox DSLR....

[eddy]

Are they worth the time/money/weight?

Just having a read about and saw some coolbox mods which a) look useful and look as though they'd do a good job...

Would it be worth making 1? I have loads of computer parts here, old Heatsinks/fans/cases/PSU's etc etc just wanting some opinions really

As from what i have read/seen the camera itself needs no modification other than getting a different battery, if thats the case, you'll find me in the garage later! lol

It's made a huge difference to my DSLR imaging Eddy. I followed Gary Honis' guide here, I've made two coolers now with different grades of aluminium sheet and the purer grade definitely gets cooler, I used 1050A grade which if fairly pure.

At SGL7 it was running at -11C, with the EXIF temperature reading -2C while shooting constant 420s subs. I've found that if I can get the EXIF temp down below 12C the banding problem that plagued my 450D disappears and the noise is generally much lower. I do get dew / ice on the filter / coma corrector if I don't heat the focuser drawtube, so bear in mind the cost of a dew controller and band if you haven't got the kit already.

Cheers,

Ian

Ok no problem, deffo worth doing then!

Will be looking into it Thanks for the reply, sounds like you have had some good results with it. Dew controllers on next on the list and i have planned for 3 now:

Focus/Draw Tube

Main Scope

Guide Scope

Think that should do it!

Thanks again

At work I've access to an almost unlimited supply of Dry Ice.

Would it also work to seal the camera in a polystyrene box with a few scoops of DI ?

Would this be too cold......?

[Gina]

Might freeze the sensor.

[badgers]

Yes..

I've come across a few sites about it, apparently you make a 2 chamber box and put a fairly small quantity of DI in one and the camera in the other.

Sounds like a lot of faff.....

I might go down the budget cooler peltier box route though later.

Assuming I don't destroy my camera tomorrow when trying to mod it : (

The one from Teleskop Express looks great, but it also looks really quite heavy

[Gina]

It is! Around a Kg as I recall.

Eddy - search for Carastro's thread.

She made an awsome, cooler box.

I'll see if I can find it.
