michael.h.f.wilkinson Posted April 20, 2012 Share Posted April 20, 2012 The APM UHC filter I have is quite cheap (39 euro for the 1.25", 69 euro for 2"), and works well in my 80 mm. A skyliner is perhaps more important, but these filters are quite affordable. Link to comment Share on other sites More sharing options...

Moonshane Posted April 21, 2012 Share Posted April 21, 2012 more aperture will enhance more objects than any filter. Link to comment Share on other sites More sharing options...
Ganymede12 Posted April 21, 2012 Author Share Posted April 21, 2012 I've decided that, with the transit of Venus coming up, I should buy A solar filter for my scope because no matter how big my scope is It would be very unwise to look at the sun. Not to mention the Transit of Venus is a spectacle that won't occur again in our lifetime. So in short I would like to know:1) How do I know that a solar filter is compatable with my scope?and2) How do I know that it is safe to use?P.S Do Solar filters fit onto the eyepiece or the objective lens?

Ganymede12 Posted April 21, 2012 Author Share Posted April 21, 2012 So how do I know If the solar filter will fit on my telescope? I found this filter on FLO First Light Optics - AstroZap Baader Solar FilterBut it comes In so many sizes! Which one would fit my scope? Link to comment Share on other sites More sharing options...
garethmob Posted April 21, 2012 Share Posted April 21, 2012 Basacaly you have to make a holder for the solar filter as long as its properly done its fine and really safe. Personally I wouldn't look with out a Coronado but that's me. I have a solar filter for my new refractor but for me im gonna image with a webcam but there's loads of members who view with it perfectly. So it is 100%safe as long as its secured properly. Merlin_66 is a solar expert he will be able to help. There's also loads of DIY threads on making the solar filter fit in the DIY section Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I found this filter on FLO First Light Optics - AstroZap Baader Solar FilterBut it comes In so many sizes! Which one would fit my scope?If you measure the OD size of your aperture and visit a crafts shop you can obtain an adjustable wooden embroidery hoop as they are made in many sizes from about 4" dia working upwards in I think inch increments, it is then just a matter of obtaining the Baader Solar film and attaching it to the hoop, just one idea to make your own, as the hoops are quite cheap to buy, the same goes for helping to fix homemade Bhatinov masks etc John.
