For your consideration. Ultra narrow Iron line imaging filters.
One unmounted 58mm 5nm fwhm energy rejection filter (center @ 529nm )
One 2" baader planetarium G-ccd filter
Two 1.25" mounted ultra narrow Fe2 bandpass filters. ~1 angstrom fwhm each. center @ 531.7nm
The two matched narrowband filters are for isolating the Fe2 double line at 531.68nm
These four filters are brand new still sealed in their factory wrappers. I custom ordered these and have no plans to use them. I am stepping away from astronomy and getting rid of all my gear.
I will include a 1.25" Skybender tilting module.
If you want to try something new, that nobody else has. Here it is. I have no idea what kind of images you can get, it is a mystery (i expect performance to be similar to the green magnesium quark @ 1/3rd the price http://daystarfilters.com/Quark/MgIQuark.shtml).
You have to complete this system yourself.
Free world wide shipping.
Asking $540.00 (I PAID WAAAAY MORE!), Please private message or email me if you are interested.
The narrowband filters are manufactured by andover optical and are .1nm each, (not .2)
The 529 energy rejection filter is also andover, is 58mm and unmounted. It is blocked xray to FIR. (matched for this system)
VENDORS WELCOME! Please, only solar equipment.
