  1. NOW SOLD. As new, pristine optics, capped and boxed. Not half bad. Each features fold down rubber eyecups and a generous 16mm eye relief for viewing comfort, making them suitable for spectacle wearers. Each model features the security of rubber grips and the eyepiece barrels are threaded for standard 1.25" filters. Price £50 inclusive of postage UK.
  2. £15 includes post to UK. Metal body, rugged grip, cemented doublet fully multi coated (FMC) achromatic lens, results in high resolution, contrast and colour correction. 1.25" barrel. Boxed with both end caps. In new condition - no longer used as I have moved to a Baader Barlow.
  3. Must be clean, preferably boxed with end caps.
  4. ...is what I'm after, preferably with end caps and boxed. But will consider without.
  5. I'm thinking of doing some visual (white light) solar astronomy with either an ST80 or a 150mm Dob. Thing is, would it be better to use a Baader Solar filter across the full aperture of either or use the offset 50mm aperture built into the caps of these scopes. Is there any advantage/disadvantage either way apart from the cost involved?
  6. Asking £50 inc post to UK - or make me an offer In very near mint condition this PanaView eyepiece features a 5 element construction with giant, oversized eye lens elements. Ideal for low power, deep sky observing. It features an impressively wide 70 degree field of view. Eye relief of 24mm, ideal for spectacle wearers. Fully broadband multi coated with blackened lens edges and parfocal. Accepts 2 inch threaded filters. Soft twist up rubber eyecups for comfortable viewing. Finished in high gloss anodised aluminium with knurled rubber grips.
  7. COMPLETED - Withdrawn In very good condition. No marks or scratches. With endcaps – boxed. £30 FREEPOST TO UK
  8. NOW WITHDRAWN In very good condition. No marks or scratches. With endcaps – boxed. Features include two ED glass elements and fully multicoated edge-blackened optics for excellent colour, enhanced contrast, high light transmission and minimal ghosting. The six-element / four-group design minimises field curvature for a nice flat field, even when used with telescope f-ratios as fast as f5. Modern twist-up eyecup, 16mm eye relief and 21mm diameter eye-lens makes it comfortable to use, even when wearing eyeglasses. The tactile rubber grip and milled indentations make it easy to handle in the dark and the 1.25“ nosepiece includes a safety undercut so the eyepiece is less likely to slip out of the focuser. The 1.25” nosepiece is also threaded to accept 1.25“filters. Asking £34 inc post UK
  9. It's a Skyliner 200p. Would it not be easier to shift the secondary a few millimetres toward the primary instead?
  10. Just a quickie. After collimating a reflector and doing a star test by intra and extrafocus, I noticed what appears to be the shadow of the focuser intruding into the image. I've never noticed this befor and I'm not sure if it is correct or not. On re-focusing normally there seems to be no ill effect. I managed an easy split of a 6th mag pair with 1" separation, so clearly not too detrimental. Here is a visual mock-up of what I'm ranting about. Any opinions welcome, because collimation paranoia is bound to set in before long.
  11. Hi folks, I'm hoping someone out there has done this already, but I have a small reflector (Skywatcher Explorer 130/900) which is I think is seriously in need of collimating. Problem is the primary (which is spherical, btw) is not centre spotted. That in itself is not an issue but removing it from the tube just might be. My question is - do the retaining screws have nuts holding them in place on the inside or are they self-tapping? If the former, then how do you refasten the screws, without having to remove the secondary spider to allow one's arm to reach right down to the mirror end just to hold the nuts in place whilst the mirror is secured after spotting/cleaning???
  12. I need a heads-up on a Circle T Japan k.40mm eyepiece? I guess it's a Kellner, but anyone using them nowadays and if so, are they any good?
