  1. Please put this thread back on a sensible footing. If you are astronomers, then act like them, and stop fooling around, we already have a Joke Box for that, It's called 'The lounge' where this one will end up If there is anymore stupidity displayed. The OP should clarify what is post is all about, it looks a bit Cryptic to me. Or Crippled, whichever description fits best.
  2. Maybe your Aluminiser used Magnesium Fluoride on your mirrors, and some catalyst has caused it to react. That substance is used in optics.
  3. Maybe we should worry a bit about Methane. Much more potent than CO2 Certainly a bad Greenhouse gas, How many Cows are there over the world pumping this into the atmosphere. I don't think we can consider grounding Rockets, and I'm sure other propulsion methods will come before many more years elapse. Man's destiny must be out there, Earth won't support life indefinitely, so Man needs to reach out, probably beyond the Solar System, because an expanding Sun will devour the Inner planets. and the outer giants and moons will be in perpetual darkness. Not for a long time yet though, but the thinking must go on if survival of the human race is to be possible. Nothing like making plans very early .
  4. I watched a recorded nasa programme on the Hubble, from the time they realised the mirror had spherical aberration, rendering it an expensive flop. The subsequent repair using a system of corrective lenses, (Costar), cured the problems. The prog. went on to cover the various repairs and equipment upgrades to increase the telescopes capabilities. Feats of courage, superb engineering, to allow this marvellous instrument to continue bringing those fantastic, and often unbelievable sights of the Universe with unbelievable definition, to our eyes. Gentlemen, the current best telescope is the Hubble, and whilst we all enjoy our own instruments, be they big, small, apochromatic, or achromatic, binoculars or spotting scope, the same old saying holds true. The best scope you have, is the one you are using at any one time. Money is always going to dictate the differences in sizes and quality. What really matters, is that when you venture out with whichever instrument, for an observing, or imaging session, you still get that buzz of anticipation. That's what it is about, nothing else. If the session is a disappointment for whatever reason, take a look at some Hubble's cosmic wonders, and dream on, and be grateful you didn't spend the amount of money Edwin Hubble's namesake did.
  5. Today Olly , but as we know spelling errors can soon be corrected. On the subject of your subject, It is a beautiful double, and It's one I would always present to any guests at my Obs. Invariably it was very warmly received,. and the description of "Isn't that just a pretty sight" would regularly be heard. One would think Albireo had been deliberately plonked into that star field, each complimenting the other.
  6. Tell your good lady it's a Time Machine, and If she doesn't stop whinging, you'll send her back to being 5 years old.
  7. Best of Good Fortune Doug. The planet is low in the murk, but you might just dig something good out.
  8. Sempei, your Latitude is around 38 degrees N. So your view of Saturn would be a lot better than here in the UK. The planet is higher in the sky, so perhaps you will be getting your good return from the planet soon. Just Stick with it. You need much patience to practice Astronomy, Observational, or Astro. Photography.
  9. You will need a good seeing night, and an unobstructed Southern Aspect to view Saturn. It's declination is quite low which means the earths atmosphere is much deeper to penetrate at such a low angle. You may get lucky, and get a decent sight of the ringed wonder, as long the air is steady, with no turbulence. It is a sight never to be forgotten, I wish you good luck.
  10. Saturn is at declination minus 21 degrees, so unless your southern horizon is clear of obstructions, the planet will.be difficult for you to get your scope to it . Add to the warm temperatures dropping as the evening air cools, the seeing would not be all that good. Your telescope should be capable of presenting you with WoW views, so maybe there's something not right. Perhaps you live close to another member, who might be able to visit, and suss things out for you.
  11. I think I would need to test it before committing 2k. Not that I think the guy is dishonest or anything, but that graph means nothing really, a proper certificated test report from the Optician who figured it would have been good. He said he couldn't find the Certificate, he ought to have guarded it as well as the mirror itself He said nothing about who produced it, he should remember that I would have thought. I'm being a bit sceptical, but two grand is a chunk of money, although I suppose if needed reworked, It could tempt someone to buy it
  12. As John said, your eye, or camera needs to be precisely centred on the optical axis of the telescopes focuser, in order to get good idea of how good your Collimation is, or not as the case may be. The process could be described as a simple one, but it actually caused many to tear their hair out in frustration. The thing to do is Identify the elements you are looking at, because what you are seeing are multiple reflections of the parts that make up the optical train of your telescope, they can be puzzling. There are many ways to approach collimating a scope. Some good advice has already been provided in the thread. Choose one, and have a go at the job. If It needs doing, it has to be done right for your instrument to perform at it's best, seeing conditions prevailing of course. Scope temperature, earths atmosphere, can play a role in poor images. In these warm summer temperatures, allowing your scope to cool to ambient temperature is a good thing to do. Good luck, and try not to get too frustrated, it will get easier as you become familiar with the process, but initially, it can be a Mare.
  13. I have to Confess, (appropriate I guess, considering the Topics subject) , but I knew nothing of an Observatory in The Vatican. I watched the programme via iPlayer, and enjoyed it thoroughly. There seemed to be no conflict between Religion and Science, and I was astonished by the knowledge of Astronomy, both old and new displayed by the Observatory Staff interviewed. The whole place was a revelation in both knowledge, and beauty. Those gardens are something else. I think I got an education watching that.
  14. How did I miss that, I must pay more attention .
  15. , I fully understand Olly, I'm also at an age where comfort at certain body distortions are to be avoided at all costs, It's not very nice inducing severe cramps in the Dark. I'm sure you'll enjoy the 14", and the easy acquirement of the targets you seek.
