  1. Something like the attached picture. Just brought a 60mm refractor from the 1980s back to life but the original diagonal is a sloppy fit. A straight adaptor proves the 'scope works perfectly with 1.25" EPs but a decent diagonal would be the cherry on the iced bun. They are readily available in the States but can't find a retailer here. So, if you have one gathering dust that you've been reluctant to throw out please let me know.
  2. Simulation Curriculum Corp did reply to my message and referred me to the forum where users have successfully run their 'scopes from the version, SkySafari 6 Plus on Android so long as Sysnscan is running in the background. I'll give that a try before going for the Pro version. I hope the responses concerning IOS will be valuable to iPhone users.
  3. Thanks for that. I noticed Google Play offer a refund but I'd rather get it right first time if possible.
  4. Before I splash out £18.49 has anyone succeeded in driving the Skywatcher AZ-GTI Freedom Finder using Skysafari 6 Pro wifi on Android? The developer's forum suggests it's still work in progress but the last date is May 2020. I've just emailed them but don't expect a quick response. I don't have a problem with the Skywatcher's own Synscan Pro but think Skysafari might offer more.
  5. Thanks for these very helpful responses. If it were mine I might be tempted to spend time and money to bring it more into line with current models but I suspect the friend who discovered it in the possessions left behind by a deceased partner will take no more than a passing interest in its qualities. Once I've taken a look at it I'll be able to gauge his level of interest in improving the 'scope and possibly acting on the good advice given here. Thanks again.
  6. A friend has just unearthed a motorised 'scope which I calculate is at least 20 years old. The Meade 4504 is a 114mm Newt on a GEM. I haven't had a chance to look at it yet but if the optics are OK and the electronics still work the principal drawback seems to be the focuser will only take 0.965" EPs. What he has are probably those that came with the original kit and, therefore, probably not top quality. If everything seems optically and electronically sound would an adapter to take 1.25" EPs be worth exploring? Somebody out there must have tried this and if it's a non-starter I'd rather not waste his or my time trying to make a silk purse out of a sow's ear. On the other hand, if it's feasible I'm happy to give it a go.
  7. My SW 12v 17Ah power tank has been locked in a barn for 5 months waiting for me to escape lockdown and come and recharge it. Having arrived a couple of days ago I was too late. The poor little devil had upped and died on me. From a number of old posts here and on CN I see that people have replaced the original lead/acid battery at low cost with some success. Has anyone done this recently and what battery was chosen, please?
  8. It's been very interesting to see how this thread has led to so many insights but, ironically, the Polish dealer's offer that prompted me to open the topic now says the 2" version is no longer available. I guess there's a good reason!
  9. I wish I could advance this discussion with the same level of knowledge and experience as you chaps but my 2" visual back arrived today. Focusing on a neighbour's chimney stack about 100 yards away I compared the performance of a 1.25" 25mm Celestron plossl with a 25mm ES 2". With the plossl I counted 7.5 courses of brickwork but, with the ES, 11 courses, a difference in view of 47%. There was no vignetting as far as I could discern. However, the plossl is reckoned to have an AFOV of 52° while the ES is marked as 70°, a difference of 35%. To my (probably over-simplified) calculation it would suggest therefore, that by using EPs with identical fields of view there would be a net difference of 12% in favour of the 2" format. In some circumstances that 12% might make a difference sufficient to justify to some observers the use of a 2" diagonal with 2" EPs. If my view of this suffers from being too naive treat me kindly and blame it on my age. As it was, I was equally thrilled with the image I got through both EPs as my new set-up is now complete.
  10. Having started this thread I've been interested to see how it's developed, especially since I bought the Omegon from John! I'm still awaiting delivery of a 2" visual back but as soon as that arrives I'll hope to make a comparison of lunar views using a 25mm ES 2" and a 27mm 1.25" Orbinar flat field. Not a direct comparison but close enough, maybe. As John has said in other posts, the Omegon is a true 127mm so vignetting should, I imagine, be even less noticeable using the 2" but I certainly hope my ancient eyes will get added benefit from a 2" option. I asked the question originally because the Skywatcher 127 is available with a 2" option in Europe, (and I believe Canada) at minimal extra cost, but not in UK. FLO, at my request, were asking the importers why it was not on offer to UK buyers but I've had no response. It's irrelevant now anyway since I'm delighted with the Omegon.
  11. Thanks. I was the very happy purchaser of an Omegon 127 Mak from an SGL member a week or so ago. This will take a 2" diagonal so I'm happy to draw a line under this now.
  12. Hello, John, Just discovered your review of a couple of months ago where you have posted a number of pictures but also describe a number of modifications you have made. As this will be a step into unfamiliar territory for me from my Celestron 4SE I need a little hand-holding. Can you please confirm that all I will need is a diagonal with an SCT thread to fit the visual back.
  13. By the way, shipping will be to Surrey, not SW France! Any chance of a picture showing the diagonal as fitted before you ship it? Thanks.
  14. Thanks, John. Not sure I'll be able to match that quality myself but having slept on it I think I would like to buy ithe OTA Please PM me with your PayPal or bank details. I would use PayPal friends to avoid charges and that would be easiest route for me. I look forward to hearing from you. Peter
