After a shift in directions on my ATM plans, I find myself with the following items surplus:
1) a Novak spider for a 21" inner diameter scope assembly
2) a 3.1" Novak secondary holder
The secondary heater in the attached picture is not for sale!
Both Novak units are in excellent to "like-new" condition, except that the spider doesn't have the four screws and washers for attaching it to your secondary ring, and the two mounting nuts on the 3/8" stud of the secondary holder have the paint marred from use. (Total replacement cost for both units is under a dollar's worth of parts at your local hardware store. I haven't done it, since the length of the screws needed for the spider will depend on the thickness of the purchaser's secondary ring.)
Each piece priced at $25 before shipping. The spider will be moderately pricey to ship because of its size (when the previous owner sent it to me it was $11+... so let's say $10 in CONUS by US mail). The secondary holder would be a freebie if you're buying the spider (it doesn't weigh much), or $4 (in CONUS) if purchased on its own. I can do Paypal if you want to add 3% for their surcharge.
