Solar film filter for ED 80

Hi Guys,

Looking for a place that sells that solar film stuff for my 80mm scope and 50mm scope. plan on doing some solar DSLR and finder scope webcam photography in preparation for June and November. This will be mainly photographic, not much visual as I have a weird thing about sticking my eye to any scope fitted with a filter....

Also while I am at it, whats a good way to wash this stuff? I have one for my 8" scope but it hasn't been used for a while and not sure if it's still okay, been in a cupboard and has a bit of dust on it.

Bintel has film. Go to their site, choose Solar Observing, it's the last item on page 5.
You will probably have enough left over to recover your old filter as well.

Just had a reply from Bintel saying they have no film in stock and unable to source it from their supplier.

Andrew,
If the filter is OK, ie hold it up infront of the eye and look through it at the Sun, any bright pinholes should be sealed with a small dab of Tippex (oe similar)....the dust should blow off with a Dust rocket blower....it should still be useable.
I have Baader film filters which are almost ten years old and still going strong.

Not sure Merlin, I had it on my camera and looked through the view finder to align the sun, image was too bright, BUT 3-4hrs later I developed a pain in my left eye (same one I look through the camera with) Pain was similar to welding flash, It eventually passed after a few hours. Hopefully nothing bad happened, but eyesight today feels fine. I have since scrapped it and will get another to be on the Safer side...

Andrew,
Hmmmm, not sure what happened there....
The good news is that in all the research we have conducted worldwide, we have NEVER found a documented case of severe eye damage or blindness caused by "accidents" with telescopes and solar filters. Not one.

Thats okay Merlin, I ordered some new film today so will be hiding this away in a draw instead of a cupboard, so should last a while longer. I am not 100% sure it was the film but there are safety disclaimers saying about using the photographic stuff visually.. I guess there is a chance of something that could happen. Hopefully with the new film I wont have any problems... Visual film as opposed to the Photographic stuff I had.

Hi

Just a query on the use of Baader film and I suspect this has come up before... However, I have never found any guidance (or probably haven't looked hard enough).

What diameter should the "filter" be, for example for a 65mm refractor? And, also for a 100mm refractor?

Thanks

Andrew

You can go full aperture with it on those size refractors, I have had it full aperture on my 8" scope also.

Hi Andrew,

I recently got myself some Solar film for both my 80ED & my 8" skywatcher. I got it from Ozscopes, the cheapest i've seen for Baader solar film (http://www.ozscopes.com.au/baader-as...fety-film.html). They usually have some in stock, if you haven't bought it. Making a mount for the film is really easy, some cardboard/staples/foam is all you need. Had mine done in about 20min, and is really strong.

FYI from my experiences, the 80ED outperforms my 8" simply because larger aperature also magnifies turbluence. It's a great combo, Ive attached some images as I also mainly use it for photography purposes. These are single shots with a Nikon D80, Straight & with a Televue 5x Powermate.
