Questions about binoculars's solar filter...
Posted 14 May 2004 - 08:39 PM
I bought C102HD and I enjoy about that scope with only Fringe Killer filer...
But I didn't buy solar filter and I want to watch the sun,
then I'm looking for binoculars's solar filter but I have
question about it.
There are two diffrent types of binoculars's solar filter and diffrent costs...
If I gonna buy that solar filter I'll put it on my Olympus
(10x50) binoculars as only watch with eyes. But i don't
understand about which thing is diffrent and why it has diffrent costs...
Can you tell me about which solar filter is better watch as only eyes?

I think it was sky and telescope that did a comparision with different glass and polymer filters. The polymer filters were equal to or better than the glass filters.
Buying a sheet of solar film and making your own filters is cost effective and easy. I made filters for a pair of 80mm binoculars, 80mm scope, and a 127mm scope from two A4 sheets with some material left over for other things. For the binoculars, I simply used a pair of cut out slip-on lens caps for the filter cell.

two more question
You mean the polymer is better than glass?
Can I use it long time(like 5 years) and is it can be cut or break?

I've had my filters a couple of years now and I have no problems. You want to store them were they cannot be damaged and check to see there are no pin holes before using them. But they are no more difficult to keep than any other filter. If you do a search for Baader Astro Solar Film of Baader Solar Filters on Cloudy Nights I'm sure you will find more feedback from other people who have used it. I've never seen a bad review.

Is that right? If you're watch the sun with the binoculars
are you using extra holder between solar filter and binoculars?
Hmm so many questions on there

Keep in mind that photographic rated solar filters are NOT for visual use except with additional filtering.

In answer to your question about looking at the sun with binoculars. Never look directly at the sun with binoculars or a telescope (or even directly with your own eyes) without a proper solar filter at the front of the objectives (front lens of the binoculars or telescope) similar to the photo Wilash posted.
If you will use the Search feature at the top of this page and type in Baader, you will get many threads/responses on how people have made Baader Astro Solar Filters. Several of those threads will have photos and descriptions of how the people made their own filters.
It is no good if the filter is put at the eyepiece. The filter has to be at the front.
Good luck with your observing and remember not to look at the sun without proper solar filters.
