Thousand Oaks Solar Filter 4.5". I purchased this solar filter on Astromart about a month ago. It does not fit my ST-80 set up. Therefore I am unable to use it.
Filter is clean as far as the lens but the metal face rim does have some minor scratch markings. You can view the photo.
Will sell for $45.00 including shipping to lower 48 cont. states. I will accept Postal M/O's, cashiers & personal checks. Personal checks will have to clear before shipping. Paypal (account transfer), OK too.
Thanks for looking.
