Accessories for TMB refractors
Here is a list of some useful accessories for the FeatherTouch 3545
focuser that comes on several models of TMB refractors for anyone
interested or thinking about purchasing. I use all the ones listed
below and they are very high-quality and work great:
1) Starlight Instruments "AP Endcap"--replaces standard clamp ring
endcap and has the standard AP 2.7 inch female threads: $67
2) Astro-Physics 2.5 inch threaded extension piece (PN A1008):
physics.com/products/accessories/focus_adap/focus_adap.htm#4 ($30 ea)
You'll need two of them for certain camera configurations. They are
stackable, very rigid, and precisely machined. They thread directly
into the AP Endcap mentioned in #1 above.
3) AP 2 inch male threaded adapter for SCT accessories (PN ADA204)
Threads into the Starlight Instruments "AP Endcap" (see #1 above),
and may be stacked with the extender pieces mentioned above in #2.
Use to attach 2 inch SCT accessories such as SBIG's AO-7 captains
4) AP 2-inch 3-knob clamp-ring adapter for attaching eypieces, star
diagonals, Barlows, and other accessories (PN ADA2003) $50:
With the above assortment of adapters, you can attach about any type
of typical imaging CCD or webcam camera, Barlows, diagnonals and
eyepieces very rigidly and safely.
Hope this helps,
