Greetings all!

Just wondering if anyone has any ideas on solar filters....pricing,
sourcing that sort of stuff....

Thanks in advance,

General consensus seems to be that the Baader film is the best thing
available. It has the advantage that, if you're at all handy, you can buy
just the film and make a holder, thereby getting a really good filter at a
really cheap price.

Watch those DSCs - I've seen a couple of guys who would go out to the
observing site, set up the scope, fight with the DSCs for several hours and
then it's time to pack up. Do the fighting at home in comfort, in the
warmth, in the light, in a clean environment. When you are sure they are
working and you can set them up faultlessly every time then take them
observing - don't waste your valuable clear sky time playing with hardware.

Rick,

Any idea where (hoepfully in Ottawa) I could find this Baader film???

PS, I am working the DSC problem at home, rather than during
observing time...it's too precious to waste!

I believe Focus carries it, though I'm not sure in what sizes.

I just picked up a solar filter from Focus Scientific yesterday. It is a
Kendrick Baader film filter for my 8" SCT. It cost $128. When their
shipment came in last Wednesday, they had three of the 8" filters, so they
may still have one in stock.

They told me about a month ago that they also carry the Baader film material
itself, and that it'd be something like $25 for sufficient material to make
a filter for an 8" SCT. Of course, you'd have to come up with some kind of
supporting ring and mounting system. Considering that, I went for the
finished product, and am glad I did so.

I tried out the new filter last evening. It was a nice snug fit on my
Celestron G-8 (same OTA as a C-8). The filter ring has nylon setscrews on
it, although they're hardly necessary for my scope. For safety, I taped the
filter ring to the scope with masking tape too, just for peace of mind.
When I observed the sun naked-eyed at the store through the filter, the
solar image appeared to have a very slight pink tint to it. On the scope,
though, I didn't detect any hint of colour.

Good luck filter-finding. If you'd like to check out my filter in action,
I'd be glad to show it off sometime.

Hi Jean! I got a Baader solar filter last Dec. from Focus. Since I'm not at all handy,I got the pre-made 8" one and paid, I think, $129. Hope to see you Sat. at Chapters as I plan to go during the day (with solar filter).
