Hello borgs and welcome to the site.

I've used it a few times now and it doesn’t affect the image at all, so in that respect it works well but it is a costly thing. As Cosmic Geof mentioned the seestar does have an integral dew heater and used in conjunction with one of these you probably don't need anything else.....

The clear glass filter is one of those comfort factor accessories that is likely unnecessary, but now I've got it, I will be using it. Hope it helps.

Thanks M40, Cosmic Geoff and LDW1.

I've always been quite anxious around optical surfaces - have always put a skylight filter immediately on any SLR lens I've purchased. My anxiety was made worse when I forgot to let my Meade LX10 dry out after a session and put it away for 6 months - yes, etched mildew on the corrector plate. 😞

But I don't protect my binoculars so I think I'll do the same with the Seestar and rely on the heater - and ensure I let it dry out when I bring it back into the warmer house!

Latest addition landed this morning, so using one of powerlords adapters, I now have my dewshield

...

It's a clear focusing filter with a 16mm extension. Plan is to stop any dew from getting on the lens plus a small lightshield. Interesting thing is how a clear focusing filter affects the picture...

...

The picture on the left is without the filter and on the right with. It only takes a few seconds to fit so the way it affected the picture was quite surprising so it will be interesting to compare puctures at night. You might also note the change in the colour of the sky, in the space of about 5 minutes it went from ok ish to get it all indoors quick :D. The latest storm has landed so it's game over for a few days. 

 

Hi,

I'm about to purchase a Seestar S50. Interested to know how you got on with using the clear focusing filter as a protector and if you are still using it. 

Cheers.
