  1. Thanks John. I'm delighted with it. Already bunged on a decent 2" diagonal and extension tube, got the balance point right, and built a storage stand from the foam packing it came with. I'm sure it's gonna live up to expectations! Doug.
  2. Steve - look at my original post's image - can you spot my Dob in there, left of centre? Doug.
  3. To Dave's ( @F15Rules ) list I would add: # higher focal ratio, so less CA, better depth of focus, less field curvature, more forgiving of eyepieces, and max exit pupil not excessive (so better contrast at low power) # in short - a good all-rounder: good mag, quite good aperture, and ditto field of view # looks like a telescope rather than a dustbin (only joking! ) Doug.
  4. My eighth (although I didn't keep them all - 4 fracs, an MCT, an SCT, a Dob, and a Newt). I've wanted a longish focus frac for a while, and didn't fancy the cost, weight, and extra cooling for a triplet, so I've gone for the Bresser Messier AR 127L/1200 Achro. A little CA on bright objects is not a problem (even less so with a higher ratio). And I expect it to be sharp and contrasty, with good depth of focus and only little field curvature. The R&P hex focuser has a smooth and slop-free action. The straight-through finder has great adjustments on two rings, and with magnification and crosswires should be fine for locating and tracking, inversion notwithstanding. (If it proves tricky, I'll probably go for a non-inverting finder with illuminated ring reticle.) It is big - almost as much a shock as when the 10" Dob landed. From the front of the tube to the base of the diagonal is 136cm. The handle between the tube rings is certainly a blessing, and the Skytee II is a good platform for it. (The home-made counterweight is serving well.) I'll be fine with it, but keep hearing, "Where are you going to store that?" I must say, this thing really looks the business - to my eyes, more so than any other 'scope I've had. Can't wait to put it into action! Doug.
  5. For me, it has to be the Perseus Double Cluster - easy to spot regardless of pollution and the Moon, and it's something I can just get absorbed in and fascinated by. And I also agree with Steve - we are so lucky to have the beautiful Moon so close with its wealth of detail - hugely varied, often subtle, and ceaselessly changing. Doug.
  6. Sure is Rob - it's a fine 'scope, and I believe a good price. I'm only selling because I have other fracs that do the job for me. We can exchange further info/details in Messages. Cheers, Doug.
  7. I reckon the whole collimation thing has been blown into something unnecessarily worrying. I went through that before getting my 10 inch Dob, but when I got it, I just did the process by eye, then finished off the primary with a simple cap. No Cheshire, no laser. And the views are crisp and clear. So for me, a cap is all you need! Doug.
  8. Price drop for quick sale: For the OTA, RDF, storage stand, improved dovetail bar, upgraded diagonal, but NO EPs - £125.00 (or very close offer!). Cash on collection from Southport. Doug.
  9. Neither does our daughter. We love going there - no bombardment of bias, gratuitous violence/anger, and irritating arm-waving. Really should follow her example! Doug.
  10. Having had a great Moon session in the late afternoon, I was out again with the Dob after a meal intending to see some lesser-visited Aries doubles. I concentrated on the region near Hamal and Sheratan. (Already viewed Lambda Arietis and Mesarthim however.) 30 Arietis - (2) + (2), two close/very close pairs - 38" separation - an easy hop from Hamal - at x35, saw two close, bright, matched stars in a sparse field of fainter ones. 33 Arietis - just beyond the 2+deg for the above - (2) + 1 with 28" of separation - again appeared as a close pair at x35, but the companion was much fainter. Using x64, the split was better, and the secondary was clearer with improved contrast. 14 Arietis - also known as H VI 69 (H standing for Herschel) - a triple - 93" and 105" - again, an easy hop from Hamal - at x35, I only saw one faint companion, but at x64 the other one showed up, about 120deg away from the first making a squat isosceles triangle with the primary at the apex. 1 Arietis - 2.9", a tighter pair this time - in the same 2+deg FOV as Sheratan - at x35, obviously not split - at x127, just split, very close, quite matched - at x141, a lovely appearance, and focus was critical with the seeing. So a very successful second session. I briefly took another glimpse at the Moon, but it was too bright to linger on. Doug.
  11. Thanks Alan - I did a bit more with the Moon - Gassendi was right on the terminator, and to the south in Mare Humorum were craterlets casting very long shadows, plus more fine ridges resembling wave patterns on a beach. In for a meal, then some Aries doubles by moonlight. (Report to follow.) Great to be back in action! Doug.
  12. 5.00pm - Moon (high, south of east) waxing gibbous - 10" Bresser - sky clear (and still fairly bright, so lunar glare is not so great) - not been out for a while - first things I noticed were Sinus Iridum, Copernicus, and the Riphaeus Mountains. To the east of them lie the tiny craterlets Eppinger and Kuiper, then to the west is the slightly larger Euclides. Further west again and very close to the terminator is the beautiful and sinewy web of ridges including Ewing and Rubey. A fine sight in Procellarum. x159 used. Hopefully I can continue to enjoy lunar and other views as the evening approaches. Doug.
  13. Package revised - please see full details in original post, and latest asking price in the next.
  14. Jupiter and moons, Saturn and moons - very popular. But for really memorable, the Perseus Double Cluster takes some beating. As for less easy targets, Jupiter's GRS took me 2.25 years to see - and it became easier thereafter. Then there was the 34 mile long shadow of Mons Piton on the Moon. I think some of the most spectacular views out there come from Luna - so close, so detailed, and fairly easy! It just takes time to study and analyse what is on show. Doug.
  15. About three years old. Well looked after. A great 'scope for compactness and ease of use. Very nice widefield views. When new, this OTA would cost £235 and include two EPs, a Red Dot Finder, and a 45deg Erect Image Diagonal. Please note this is the OTA only - NO tripod or mount, and NO EPs. The Red Dot Finder is included, and the diagonal is upgraded to a star type. The very useful stand is included. (See photos.) The dew shield on the finder is included. The dovetail bar has a few of the usual marks, and it now has countersunk screws so that it can used with a wider saddle. Very handy. One of the screws for the focuser assembly has its head sheared off, but this is not in any way detrimental, and could easily be rectified. I mention it in the interests of being honest and open. (See last photo.) So - for the OTA, RDF, storage stand, improved dovetail bar, upgraded diagonal, but NO EPs - £150.00. Cash on collection from Southport. Doug.
