Lymax Cat Cooler new
      #5484772 - 10/23/12 04:28 AM

I'm unable to keep my NexStar 8SE "outside", so must stay in the house. With cooler weather coming, also longer cool-down times. Any comments about the benefit of a Lymax Cat Cooler? Thanks-

I have one for my 11". It is worth the money.

They are definitely an effective product when you can't store a scope at ambient temperature and also in situations where the temperature continues to drop over the course of a night's viewing.

An alternative to the commercial units (which are very nice products) are home made coolers using PVC piping and a small muffin fan. You can usually do this for under $25.

+1 they are super and make it possible to use your instrument more frequently.

On those nights when the sky is a big question mark. You decide to wait a bit and see what happens. Later you look and it's great - however you figure it's too late to setup and cool down. So, you pass. Not with the Lymax! Set it up and you're good to go in 15 minutes. Even on an 11 or 14.

Best, Joe

It cut the cool-down time of my 9.25 inch SCT by more than half, so it has been a wonderful help. Here is a review of the unit:

Another enthusiastic "+1" for the Lymax. The bigger the scope, the more necessary they are. Lymax really hit one out of the park when they came out with these.

Thanks for all the great info, and David, the CN Report. Plan to purchase ASAP. Nice to know I can change out the vent tube and use same unit with CPC 9.25 as well. Take care-
Bruce

Brandon, Mississippi - nice place!
What sort of eyepieces do you use in your 8SE?

Thanks, Rick-
My 2 favorite's are TV 19mm Panoptic and 32mm Plossl. Also occasionally TV 11mm Plossl. I've been wanting to consider some other EP's. Do you have some suggestions?

OK, you asked, so...

Try some Brandons! I personally swear by them.
There are threads galore all the time on them in the eyepiece forum, and if nothing else they'll provide some entertainment.
Caveat: Brandons appear to work much better in longer focal length telescopes. At least, that's what a lot of people say.

What about the dust that is mentioned in the review by David Knisely? Anyone have a problem with the dust? And what's the life of the filters? I see they are not recommended for Celestrons HD SCTs. Do they mean Edges?

As the Edge HD design has a correcting lens in the baffle tube, the Lymax cooler will not fit in the Edge HD scopes.
I have used a Lymax Cat cooler for several years in my C11.
I have never had an issue with dust inside the OTA from the cat cooler.
The filters last a long time, and can be replaced easily.
Similar filter material can be found at various hardware stores, and can be cut to fit the Lymax.
