Recently acquired a Borg 60 ED. Marvelous little thing. Weighs in at
one pound, or just under half a kilo. Perfect little grab-and-go
scope.
I've missed a few star parties because the weather looked dodgy and my
10 inch SNT is such an endeavour to pack, unpack, set-up, tear down,
pack and unpack. The SNT is marvelous for DSO observing, but I've
needed something I can grab in an instant and take to a viewing site.
Also the Borg is small enough to take to work and do some viewing
afterwards. I'm afraid I'm now hooked.
Hutech has quite an impressive array of add-ons, but I do not see a
solar filter among them.
I'd like to obtain a solar filter, the shade takes a 62mm thread if
that's any help. |

Great! Good to hear you're having fun with it. (Have you named your
scope?)

What kind of solar observing would you like to do? If white-light, you
can make your own solar filter on the cheap with Baader Planetarium
AstroSolar film. Costs something like $20 U.S. per sheet, depending on
size. (Been a while since I've ordered, so the price may have changed
or I may be misremembering. But it's economical.)
If you're interested in doing H-alpha viewing (so that you can see
prominences, flares, filaments, etc.), that'll cost you a pretty penny.
Probably the most inexpensive solution is to forego using the Borg
altogether and buying a Coronado PST. For better resolution, Coronado
also makes a 60 mm H-alpha filter. (They also make a 40 mm filter,
which is somewhat better than the PST, and a 90 mm filter, which your
scope naturally would not be able to use.) Any filter you use with
your Borg will require also a mounting adapter and blocking filter, both
sold separately. The PST, on the other hand, is wholly self-contained.
Good luck.
