LUNT SOLAR - Ca-K Module with B1800 Blocking Filter in Extension Tube for 2" Focuser
This Calcium-K module transforms your normal astronomical telescope into a Ca-K solar telescope. It will be very easy: Put the Ca-K module into the 2" focuser of your telescope, and you are ready for solar observing in the light of the Calcium-K wavelength.
Internal narrowband filters allow for a <2.4 Angstrom bandwidth. The Ca-K wavelength is at the edge of the visible light spectrum for human eyes, so for many people visual observing is difficult. However, all details could be captured photographically. Therefore the Ca-K Module is optimized primarily for imaging.
For telescopes up to 100mm aperture and up to 1620mm focal length. For imaging it will be better to use a bigger Ca-K module.
The Ca-K module is in a straight extension tube, for 2" focuser on the telescope side and with T2 connection and for 1.25" eyepieces on the eyepiece side.

Contacting telescopes.net I was told the version I ordered off the website was not in stock and would take a month or two to get and send out to me. I was told to keep the diagonal version and use it until the correct one arrived.
I am totally astounded by this kind offer!
I haven't taken it out of the box yet but it is going to be hard to not use it whenever the sun is out from behind the clouds again as is predicted to happen later this next week.
I know this isn't totally a product review but I hope this review of service is accepted via this channel. (Posted on 3/15/2014)
