Dehumidifiers For Observatories - Any Suggestions
« on: Jan 13, 2020, 23:53:57 »
Crikey! my ID still works. Hi to those who remember me...

Does anyone have a suggestion for a good Dehumidifier for use in an observatory, will need to deal with cold - If it ever gets cold again and to run 24x7.

Thanks & all the best

I use the DIO (Dry It Out) Dehumidifier.  The company owner is an amateur astronomer and I have had good support in the past when I needed it once, Mine is like the £129 version and works in the cold, dries out the obsy really well. 

Don't know how you've managed without one Paul.

Hiya. *waves from the Cotswolds*

I suspect the ex-Chairman's cat's account may still be around, too...

Hi Carole, thank you for that, I’ll take a look at that one.

Roger, Nice to meet you via forum

Hi Rick, yes I did see that Oscar still had a presence, sadly he won’t be posting any new forum notes.

Hi Paul!

My obsy just has gaps for air flow, not all intentional. Was the obsy with the two level fold out roof your one? You could always take a hole saw to it  :surprised:

Hi Duncan,
Yep that's the one. Most of the time it's nice 'n snug it has a bit of air flow around it and is mostly dry. The Obsy is on posts so it also has a gap under the floor so gets air all round. However this winter has been so bad.If i'v been out observing (Ha Ha what chance have we had since September) when we have hit the dew point and the mount and scope are dew'd up on the outside then shut up the roof if still takes a while to dry it all out. That's when I need something to help dry things out.

Dew heaters on the mount and ota all the time or on a timer. I tend to leave all my stuff on all the time to keep the moisture at bay, there is a stream 20ft away so the ground is always damp, so my obsy floor is 1m off the ground.

Personally with English weather I don't think it is worth taking the risk of not having a dehumidifier.  My Obsy gets very damp inside if I don't use it, of course it doesn't help that I have a small leak at one of the pivots.  I catch most of it in a bucket, but there is always a bit on the floor too where it must miss. 

1 hour with the dehumidifier on and it'a all dried out.  I definitely don't leave cameras in the obsy without the dehumidifier being on in the winter months.
