Quote: iStar optical 6" F/12 Doublet Achromat lens in cell. Since retiring I have lost my mojo on this project,so this excellent lens is up for sale. I have built refractors before using these excellent objectives and suffice to say they have never let me down. The optics are spotless with very nice fully multi-coated unblemished coatings.
Price is £300 including postage in the UK and any PayPal fees.
