In basically as new condition, with one slight mark on the barrel which was there from new. This is a Revelation fully multi-coated three element x2.5 Barlow. It has a non marring compression ring fitting and is 1.25" format. Has both caps but I don't think I have the box still.
Looking for £20 plus £2.50 P&P via PayPal fees paid or bank transfer.
Offering here first, then will put on ABS at the weekend.
Mainly for my TV Genesis, I am looking for a 2 inch, 2x Barlow for use with LVW 42mm & NLVW 30mm eyepieces.
To have good quality 21mm & 15mm equivalent eps with 2 inch fitting.
Prefer to be able to insert the Barlow fully into my diagonal's ep end. 2x isn't exact magnification, as optical quality is more important. Any increase in eye relief is OK so a TV Powermate's speciality in not increasing the er is not essential.
I decided to try a decent Barlow with my rich field scope first, to see if I want to really upsize aperture & focal length in a refractor.
