Hi Michael,
I would like to buy from you the field flattener and the H-Alpha filter.
I'm based in northern part of Phoenix just 2 miles before Anthem. I can
drive and buy them from you this Saturday. Kindly inform what time on
Saturday we can meet.
Thanks,
Nikul

I have been accumulating an assortment of no longer needed items in my
office for too long, and I really need to clear some space. Before
posting them online, I'll offer them here at a bit of a discount. While
my residence is in the Flagstaff area, I will be in the Valley this
coming weekend if you see something you're interested in and would
prefer to avoid shipping. Photos of any item on request.
Astro-Physics 2.7" single-speed focuser
I have two of these, both of about the same vintage. These are the
older, so-called greased models which are not compatible with the
two-speed Starlight Instruments pinion. One has the Astro-Physics logo
on one side while the other is unmarked. I also have a flange which
threads on to the focuser so that it may be mounted on a flat surface.
All in good to excellent condition. $200 each for the focusers, $15 for
the flange.
Explore Scientific field flattener, P/N FFEDAPO-00
I bought this when I had one of the Explore Scientific 102 mm f/7
triplets and have used it with an A-P 130 EDF. As opposed to a
reducer/flattener, it slightly increased the effective focal length, but
it worked well across the field of my APS-C camera. A few dust particles
on the outer sides of the glass elements, otherwise like new with
original box. $50
Astronomik 12 nm H-alpha filter
As new condition, in original plastic container. 1-1/4" eyepiece thread.
$50
Celestron 1-1/4" prism diagonal
New old stock, not sure if it has ever been used since it was delivered
with my C9 1/4. Includes caps and original box. $10
ADM 7" Vixen-type rail
A few marks from the clamp screw, otherwise undamaged. $10
Astro-Physics DOVELM8
8" Losmandy D type saddle for A-P and other mounts. I used this to carry
a C11 on my A-P 1200 mount for a few months, but replaced it with a
larger Cassady saddle when the observatory was upgraded with a larger
R-C. Like new. $90
GSO Crayford style SCT focuser
Two-speed focuser to fit standard SCT rear cell (C8 / C9 1/4, etc.)
Mechanism is good, no cosmetic damage, includes original. $50
