Here’s a little gem. I had one a few years back , solar minimum was coming . I sold it to Peter at Todmorden ( a dream visit) . Just picked up another which shows up the current hectic activity.
It’s 35mm at 400mm ota. 25mm gives the whole disc. I use a single polarising filter which gives better contrast . There’s a bit of refocus between the disc and proms . Granulation , filaments and spots show up well . A 15mm tv plossl gives great views .
it’s ideal for grab and go as it requires no power and there’s a wee wheel for tuning up front , easy .
I’m not into photos , but I took this through the same set up a few years back . In the meantime back to the drawing board .
Well worth looking out for , as are clear skies ! cotterless45 Nick.
