This very narrow-band DayStar .54A T-scanner was made by Del Woods, internationally known h-alpha guru. This outstanding sample provides knock-your-socks-off, highly detailed views of both solar prominences AND disk details, including filaments, plages, spicules, sunspots,magnetic field lines, and solar flares!!
I have had EXTENSIVE telephone and correspondence contact with Del Woods, who made me this excellent sample only two years ago. Please feel free to call Del and ask him to verify all of the above, with regard to this filter (He knows me as "Dr. Bob" Hertel).
Also, this filter in my opinion is at least as good, if not better than,the coronado 90mm filter, and in my experience is better than the 60mm coronado. If you know these kind of filters, the DayStar has NO Central Obstruction, key to hi-res views. Note also that the coronado 90mm goes for over $4000.
DayStar filters have been next to impossible to obtain.
It took me over a year and a half to get this filter.I am selling this DayStar because I bought 2 T-Scanners from Del, since who knows when he will retire. When he does, it's Game Over.
I have decided to part with one.
The one for sale is still under warrantee, paperwork included, and comes with the beautiful foam lined wooden box the filter comes in.(ERF not included)
Trivial cosmetic mark on barrel, optics and functionality perfect.
All serious offers over 1850 considered, postal money orders only, shipping included, prospective serious buyers welcome to come and try this killer filter. This is a good faith, all-cards-on-the-table offer on a top drawer, increasingly harder to get very narrow band filter that will bring you the wonders of solar maximum NOW, which is still here in all it's glory!!!
