Hello,
A friend of mine has absolutely band new ARIES 295mm (C11) three band filter for sale. Quite recently he bought a Meade 12" and a newest ARIES two bands filter for it. So, he now willing to part with his 295mm DERF with a great discount as he need funds quickly (needs a surgery) and asked me to help him with this sale (he is not english speaking)
.
This filter has never been used before. I just installed it in the cell of my own filter on my C11 and made a few test photos a few days ago. See them below. Look closely at the first photo - it was taken in the CaK line and easily reaches a theoretical resolution even at such a short wave length ( 393nm, 1,67x shorter than H-a 656nm!). This indicates a highest optical figure of this filter.
He asks only $3000 cash in hands.
Note, that this is $2500 less than a regulat price!
If you are interested in buying this filter, contact me via PM or better via e-mail.
Thanks,
Valery.
