  1. Having a good read of BillP's review of diagonals here, should give you some idesa what to look for when doing comparison.
  2. The new Baader site is a very good face lift, specifications are added to many of their products, and some Q&As too. Accordidng to it, there's no optical difference between Mark IV and III.¼"--2").html
  3. Good one Peter, that's prety much what I saw, left-right mirrored through my diagonal though.
  4. There're some of these 5 lens in 4 goups eyepieces out there, modified erfle is mentioned here These 70° EPs are like of the same design: and 9mm, 15mm, 20mm Willaims SWA are likely too:
  5. Noce picture. Got my 120ED out last night, when the comet was much close to M108, actually the upper side of M108 in your picture. 50x-80x works well for seeing both M108 and the comet
  6. Congratulations to seeing Thors' helmet. This is my note on mag 21.0 sky two years' ago, "hint of nebula at best without filter, UHC! OIII!! Best filter neb så far" This long cloudy night season was not entirely waste, I've able to check my obs notes, clean some double posts, and come to conclusion that I have 12DSO on Herschel 400 to go, 327 Herschel II to go
  7. For casual observers, children specially, a zoom is a better alternative. IMHO, no hassel of changing eyepieces, they can easily zoom to find suitable magnifications, or just have fun. If you're not shy of buying used, there's a baader zoom (not mine) in ABS at the moment. PS. Baader's has both 2" and 1.25" nosepiece, with your 2x barlow, it works eqvivalent 4-12mm, about all you need for viewing the Moon and Jupiter.
  8. £13 for a pair of these can work too
  9. Never say never
  10. Agreed. The volcano top of 10mm BCO makes much better useful ER than many longer ER with recessed eye lens. The very good scatter control in 10 BCO makes it an excellent Solar and planetary EP.
  11. Very nice, Chris, good to have the positive reviews confirm by you
  12. Very Nice Stu Good confirmation of our eyes' inability to see gradual vignetting. Many got frightened with C8's 37mm rear baffle size, e.g. but EPs with 46mm FS just show barely detectable vignetting to my eye (and to many other actual users too). 46mm is nearly 25% larger than 37mm, so the 20mm 100° ES with 34mm (25% larger than 27mm) should show this bearly visible vignetting too, in a simplified anology.
  13. This is a little summary table I've done, as mentioned by others, SCT C8 gives you most aperture for unit weight (highest number fof brightness/weight)
  14. Near? It goes faster when you're having good time recommending BSTs
  15. Of the readily available EPs, I'd think 16mm Brandon, 15mm SLV or 18mmBCO+QT barlow(1.3x) are among the best candidates for planetary in your Mak. Brandon for their authentic plossl, i.e. unsymmetric, which has better spotsize than any symmetric plossls(actually achromat pair as shown in the picture below). 15mm SLV are among the best SLV's according to this quite comprehensive review here. you may need to use English translation to read it.
