Thanks all for taking the time to help with this and to Don for trying out a similar setup with a known "good" EP, which is always the acid test. It's clear that the issue is me not folding the eyecup to get my eye close enough when wearing glasses. As an observer of many years it's a schoolboy error - the new world of wide(r) fields caught me out! I'm now looking forward to the darker skies and seeing what a £200+ EP brings.

If i take my glasses off I can see the field stop, and i can get fleeting views where the orange/red is gone and there is a very thin blue coloured ring inside the stop, which to me is more what i expected to see. I think I'm going to have to wait to try it on the moon and stars.

Gus, yes it was in focus. Louis, I've taken your advise using a distant tree on the horizon, with the attached result. It's a good representation of the visual effect. I've never seen anything similar with previous EPs, but to be fair this is my first foray past Plossls, SLVs and BSTs into wider fields.

Hi Gus, I was using it with an 8" Celestron Evolution, so 2000mm or thereabouts. Graham

Hello SGL, I recently took the plunge a bought a 17.5mm Morpheus eyepiece. So far I haven't been able to try it at night but during a daytime check I have seen that the outer 5% of the FOV has a orange/red colour fringe which I can't eliminate via eye positioning. I'm unsure if this is the "Ring of Fire" effect. Is this normal for a Morpheus or a fault? Thanks for any help.

Hi David, Thanks for your reply. I've attached a photo. Graham

Hi, I have picked up an old C5 which has several areas where the pebble-dash grey paint has come adrift, mainly on the forks but also on the rear cell and finder bracket. Does anyone know of a suitable paint to use to tidy these up? Also, does anyone know of a source of a suitable 3-pin AC cable? The scope is a 230V model, circa 1980. Thanks, Graham
