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 can not 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 cont. 48 states. I will accept money orders, cashiers checks, and paypal (account to account) OK. Personal checks will have to clear before shipping.
Thanks for looking.
