Yeah, I was thinking: wow, that Dale, he knows something I don't know.

Years ago I volunteered my "Astro, computer, fishing, pool, collectable room" (Converted double car garage) for several of these work shops. The cost was about $20 and a couple of hours.

Sorry to say the member who put this together is no longer in the area. Also, the price of these (if you compare prices) has dropped drastically in the last few years. 

But my advice is to get one immediately !!!!!!!!  you will triple your use of your scope and see something that will not happen again in 11-13 years.

Every day some new features on going on and you don't want to miss the transit - that alone is worth the price of a filter. Courtney, I will be at the next meeting and I have a small

presentation I would like to give on observing the Sun. I have all my drawings  from the last solar peak and made a slide show.

I can not express the impotence of this particular sun cycle, and this transit. A 3/5" piece is fine for just about all telescopes.

see you at the meeting

At the January meeting there was some discussion about having a DIY Solar Filter class as a club event in anticipation of the June Venus Transit. Essentially an afternoon where folks could make their own filter with help/guidance from experienced club members who have made them before. My understanding was that the club had classes like this in the past.

Does anyone have any information on this or knowledge if this has moved beyond the idea stage? I'm looking to make a DIY filter for my 8" Dob, and would definitely appreciate all the help I can get to ensure I do it properly.

Thanks,

Paul
