New CaK 2A filter

[Merlin66]

Omega Bob had done it again!
This time a fully coated, ERF protected 2A CaK bandwidth filter!

This is ideal for imaging the solar detail in CaK.
Some of the early images are mind blowing!!

There's also talk of a CaH filter coming soon....

3 available and 7 sold - might wait. BTW how would you set this one up in the image train?

David,
It basically screws onto the nosepiece of your camera and uses a refractor - IMHO something around an ED80 would be ideal.
No additional ERF's etc. just "plug and play"
Obviously for imaging ONLY.

ok just bought it - this will hopefully complete what i wanted to achieve - image with sm40 DS for wide field, do close up visual and HA with lunt 60 and 127ED white light and now adding the ed80 with the CAK filter. now just need to rebuild the observatory ;) and the mount setup, .... and maybe a new PC or two
