I have a wide selection of 2" eyepieces and never use this
Celestron F/6.3 reducer corrector.
It will make a 25 mm eyepiece have the fov of a 40mm eyepiece
but if you have the 40mm there's no need. Reducer/correctors
cannot be used in an sct with eyepieces above 25 mm in focal
length. Well, they can be used, but you get very dark edge
of field. You don't want to use this with a 40mm, but it is a
good deal cheaper than a 40mm if you want to stretch your dollars
and only buy a 25mm eyepiece.
I've never done photography but word is these are useful for
prime focus. Consult your local discussion group.
This is used equipment, comes with both caps, I don't hold much
for saying something is in mint condition if it's used! I'm
not aware of any scratches and haven't used it in over a year.
The stated price is a solid discount over new prices listed on the
Astronomics web site.
I don't use paypal, will accept check or postal money order.
Included shipping applies to CONUS only. If you send me a postal
money order I WILL NOT CASH IT until you've received the filter(s)
and decided everything is as advertised. If you disagree, you return
me the goods at your expense, and I'll return the money order.
I also have a skylight filter which is basically clear glass that
allows you to seal an sct ota. You can leave it on while observing.
Advertising copy says the filter increases contrast. I think the
best way to increase contrast is to move to New Mexico. In any case:
I never use it, either, and will include for an additional $30 with
the reducer-corrector. Skylight filter by itself: $35 shipped CONUS.
My first preference is to sell this as a PACKAGE DEAL for $125, in-
cluding CONUS shipping, which judging from Astronomics prices is about
$65 (taking into account shipping) off the combined new price.
