WOW, I guess Id better start "pushing" my own stock of similar filters
again, before all of you guys go broke at $40 a pop! I think that the $40
filter at OPT is not multicoated...but Im not sure of that since someone
mentioned it might be Tiffen. Certainly Tiffen makes regular and multicoated
filters for normal camera sizes, and for eyepiece sizes by special order.
Ive never heard of any astro dealer selling multicoated lunar/planetary
filters to date, other than one or two who carry a few types of the same Hoya
filters which I have a wide variety of. Almost everything except red. (I
have found one lonely red Hoya filter for 2" eyepieces, so its in my
personal collection until I find a quantity of them.)
I have plenty of "new old stock" brand new Hoya 25% transmission (ND4)
filters available: a large quantity in their HMC multicoated grade, and a few
in their regular coated grade. Also 50% transmission (ND2) with regular
coating, but theyre less useful than the 25% transmission ones.
I also have Hoya polarizers and Star-D (another good, but lesser-known,
Japanese brand) polarizers. You need 2 polarizers to make a
varialble-density polarizer. By putting one on the diagonal and one on the
eyepiece, you can just rotate the eyepiece to adjust brightness, without
pulling the eyepiece out to adjust a pair of them.
Going to high power beats using any filter, but then you cant see the whole
moon. I usually prefer the ND4 to polarizers on the moon when Im observing
the whole moon. But I find the polarizers useful for people who need it
darker than me, as well as dimming the moon to the optimum brightness for
observing occultations. Namely as dim as you can make it while still seeing
the star easily.
Ill paste my list of available filters below, including the moon filters,
color filters for planets, and a few others. Id thought I was out of Hoya
polarizers, but found a few more pairs of them stashed away.
Anyone who wants filters, please write me privately at the address below,
rather than replying to the list!

--------------- 2" eyepiece filter information and prices -------------------
I have a large number of 2" eyepiece filters in stock.
They are "new old stock" in the screw cases,
with little instruction booklet, in the original boxes.
Add up the filters you want, then take the following MAPUG/s.a.a. discount:
Up to $20, take 20% off
$21 to $60, take 25% off
$61 to $160, take 1/3 off
$161 and up, take 40% off
All of the filters are Hoya brand except a choice of brands for polarizers.
All of the filters, except polarizers, are either regular ("double") coated
or HMC multicoated. Both brands of polarizers are uncoated for technical
reasons.
All have the standard 48mm thread for modern threaded 2" eyepieces,
diagonals, and 2"-1.25" adapters.
Below is the list of filter types, pre-MAPUG-discount prices, and suggested
uses.
Filter Description coated HMC Recommended for:
UV clear $10 $18 protection (dust,
etc.)
80A medium blue $10 $18 planets
80B medium blue $10 $18 planets
81A very light amber/orange $7 $10 protection, Mars
81B very light amber/orange $7 $20 MARS!!
82A light blue $10 $18 planets
85 medium amber/orange $10 - planets, MARS!!
85A medium amber/orange $10 $18 planets
85B medium amber/orange $10 $18 planets
K2 medium yellow $10 $20 planets
X1 medium green $10 - planets, star testing
refractors
ND2 50% transmission $8 - moon
ND4 25% transmission $8 $14 moon
FL-D light purple-pink $16 - Jupiter with or without
(FL-D is "minus green") 82A in combination
Diffuser semi-translucent $8/pair - endcap, storage
also good as spare/spacer threaded ring after glass is removed
PL linear polarizer $34/pair Star-D brand
PL linear polarizer $40/pair Hoya brand
Great on moon. Use 2 to make variable polarizer.
One on diagonal, one on eyepiece (or 2-1.25 adapter)
lets you rotate eyepiece to vary brightness.
Pick out what you want, then email me. Ill confirm that I have what you
want, that I can find it in my jumble of filter crates, and get back to you
with price, payment, and shipping info. Shipping runs about $5: from $2 for
1 or 2 filters uninsured in a padded envelope, to $6 for a dozen filters in a
box insured for $100.
So a single multicoated ND4 would be $14x0.80 + $2 postage = $13.20 postpaid,
or two for $28x0.75 +$2 = $23 postpaid or $24 if insured.
Please email me at JohnLX200@aol.com with any questions or to place
an order.
