I purchased this new from Coronado in March of 2001. See my Cloudy Nights review ( Daystar Vs Coronado shootout).

This is an early Isle of Man filter with 2'' BF 30 blocking filter. I have kept this filter for so long because it does not suffer the degradation (oxidation) problems some US filters have. The images today look as good as 2001 and there is no change in the blocker.

Very balanced views between the proms and disc.

What you get:
AS 190 90mm etalon
BF 30 blocking filter
T-max tilting plate
Instruction card
Pelican case

Threads onto Televue 101/102 scopes or others with suitable adapter. I will be listing an astrophysics 130 adapter separately.

This setup is offered at a reasonable price and will serve many more years. I'm selling off a lot of equipment due to changing interests so let me know if you have any questions.

Thanks,
Doug
