  1. This is something I've actually had to do recently and the winner is....... the Vixen SD81S, small but perfectly formed. I also think that, due to the terrible British weather, UK stargazers have far too much time on their hands and this is what allows threads like this one to be so popular. Not being able to get out and use our scopes, regardless of how many we may have, can be frustrating at times.
  2. Mind blown! As a "Stargazer" I love looking at the night sky, it's massive and beautiful and not of this world, but practically everything I see up there is in our own galaxy, the Milky Way. The Universe is full of countless other "Milky Ways" and I find trying to make sense of all this impossible. This is a subject which is undoubtably scientific, but because of it's very nature can't help merging with other not so scientific ideas. I'm no scientist but when I talk to my friends about these things they always come back to me with the same questions, "What happened before the Big Bang?", "How can that be possible?", "Something must have existed before existence began?". All I can come up with is "Hats off to whoever solves the puzzle"😁.
  3. I don't understand politics or cosmology, but inflation is what I do to my tyers.
  4. That's an epic dodge on your part! Take a zero off and it might be worth a punt though😁.
  5. Delta Monoceros is about there but it shouldn't be flashing.
  6. No and don't use any 12v supply for it, you'll fry it. They run off 9vDC centre negative, if you haven't got the original battery pack, you can get, off Ebay, a 5vDC USB step up lead which converts a USB powerbank into 9vDC centre negative. These leads are intended for use with electric guitar pedals like BOSS pedals which are made in Japan and are 9vDC centre negative. These leads cost less than a fiver and then you can run your SD-1 from a rechargeable USB powerbank, 10,000mAh works best and will power your scope all night long off a single charge. USB 5V to 9V 5.5x2.1mm USB to 9V Power Supply Cable for Guitar Effects Pedals | eBay I hope you read this before you plug the Halfords in! It will tick over on tracking at 12v but as soon as you use the fast forward button the circuit will overheat, do so at your peril!
  7. Yes. Vixen still produce their 4" achro, the A105M and it retails around £950 whereas a SW Evostar 4" is currently on offer at FLO for £194. Both usable scopes but the difference in price is reflected in the quality of the optics.
  8. I'd agree with that as well, it's got the wrong sticker on it. Still a nice achro, but not as good as the original Japanese version.
  9. Yeah, your older Vixen model is from the 80's because it has the attachment on the focuser for a swivel finder and Vixen have always had oversized tubes (115mm for a 102mm scope), the later (90's) Celestrons were made for the US market and may have had narrower tubes to allow for after market focuser upgrades? Not sure on that one, but the two scopes will have the same objectives, 102mm f9.8
  10. This is an old "Vixen made" for Celestron 102M, @wookie1965 it's the same scope as the Vixen 102M you've just bought, apart from the colour that is.
  11. The internal thread on the old Vixen drawtube is 43mm and the internal of the stepdown ring is 36.4mm, so if you're going to throw anything out it should probably be your calipers not the scope😁.
  12. Bresser UK | Vixen reducing sleeve 36.4–31.7 mm | Call 01342 837 098 for advice and sales. This is the Vixen part, £22 for a little eyepiece adaptor, but it's the same as what you have but for 1.25" rather than the old fashioned .965. The Baader you've ordered is a better holder all round, plus you'll have fine focusing.
  13. The .965 visual back you have is made of two parts, unscrew the .965 holder from the 36.4-43mm ring and replace this ring into the drawtube. Your Baader helical will fit straight in. Shame about the chip but the rest of the glass looks good, it will still work well.
  14. It's not just a very capable 4" ED F9 refractor but that particular model, the WT version, is actually quite scarce. Enjoy☺️.
  15. When Vixen scopes changed to white around 2002, the stock pinion knobs were indeed made of ABS but of the same design of the current metal ones. My old ED102S F9 from 2003 that is being passed around the forum at present, did have these "plastic" focuser knobs, but I thought a scope of that calibre deserved better and so put a new pinion with metal knobs on it.
