  1. Welcome to SGL, @Taman. Are the skies dark there for astronomy?
  2. I prefer ROLO - "a brand of truncated cone-shaped or conical frustrum-shaped chocolates with caramel middle".
  3. I agree about DSS. In fact I'm surprised the DSS image is as good as it is. I think both images are pretty good which suggests the raw data is good. How many subs did you take? I assume this is DSLR data. M42 is tricky because it's got a very bright core and then lots of interesting but fainter nebulosity around it. It's difficult to pull up the fainter stuff without blowing out the core. I have recently been working through the book Inside Pixinsight by Warren Keller which walks the reader through use of masks and other processes to pull out the detail. I recommend it if you've not got it.
  4. It's hands and feet I have a problem with cold wise. Core body temperature is just a matter of wearing enough. But you can only put on so many pairs of socks.
  5. Sounds like you've made a good start. Viewing by eye and binoculars with a good star map or planetarium app is the best way to start. You'll see most of the constellations as the year rotates around anyway even if your view is restricted. I'd add ursa minor and the pole star to that list. Also work through the zodiacal constellations. You've got some already, but at least that way you'll always be able to make out some anytime of the year. It also impresses people if you say there's Capricorn, Aquarius, Aries, Taurus, Virgo, Gemini etc when they pipe up "oh I'm an Arian" or whatever "I've never seen my constellation". Also it's good to be able to name a few prominent stars in the constellations - Vega, Betelgeuse, Deneb etc. And to learn some of the prominent nebulae within constellations and how to find them with binoculars, although some are visible by eye. Something I like to do on a starry night when I'm not using the scope, or even when I am, is to stand facing north and slowly rotate all the way round - north through west, south, east - identifying constellations, stars and objects as I do so. Keeps it fresh in my mind that way.
  6. That's great. I'd wished I'd had the opportunity to learn those sorts of practical skills. I'm ok with the equipment, technical, computational and science aspects. Those were key aspects of my career so I'm fine with setting up and running kit. But as for construction work, engineering and serious electrical work I'm definitely out of my comfort zone. You're right though. The great thing about this website is learning from others. Also we live at probably one of the best times ever to learn things because of the Internet. If you don't know how to do something there's nearly always the information out there that you need to do it. It's just a matter of having the guts to have a go.
  7. Yep. Lovely natural looking image of one of my favourite objects.
  8. That's an excellent job. It never ceases to amaze me the high level of practical ability amongst amateur astronomers .... excepting myself that is. How do people learn the skills and confidence to do this sort of thing?
  9. Yeah, Puritan here. Would it really appear that blue? If that is we could see it close up ..... and with eyes as sensitive.
  10. @dannybgoode Yes .... visual PA is a pain in the neck - literally! Your might find your guiding error is a tad better after PA with SharpCap and probably more stable.
  11. No problem. Topics very often come up again. I was thinking your 1" polar alignment accuracy was very good for "quick and dirty". I suppose it depends on how quick and how dirty. But I usually find it's more like some fraction of a minute of arc when aligning by eye and polar scope.
  12. This question came up a week or so back. The consensus of opinion was that it didn't matter. I use the polar alignment routine in KStars/EKOS using the guidescope. I normally do an approximate polar alignment first using the polar scope and I just make sure the guidescope can see the pole star before starting the PA alignment routine.
  13. @Lockie Thanks, Chris, for taking the time to do that. I couldn't go this time. I'd been looking forward to it for months and then events intervened. Your video gave a good flavour of the show. Interesting to hear about the Rainbow mount and FLO's project to sell its own brand ED telescopes.
  14. Just packed in. It's getting misty now and the Moon's just coming up. It was gin clear earlier. All the neighbours are away so no lights on. I decided I'd just enjoy a visual evening. No computer. Just me, the scope and the handset. It's been ages since I did that. Lovely!
  15. I decided not to go this year. I've been for many years now. This weekend is very busy for me anyway and I just didn't fancy hacking up and down the A34/M40 on a grim November day. I hope it's not going to be in November from now on. I prefer going there earlier in the year. It looks like it was a good show in the pics. Thanks for posting those. At least we can see what we missed! Was it in a different building this year? Were there more or fewer exhibitors?
  16. Just shows how modest are our capabilities of detecting alien civilisations even with this large and expensive project.
  17. @joe aguiar Well, I can only report what I've found. If the scope is loose enough to rotate then it's loose enough to slip in the rings. If it's not loose enough to rotate easily then in applying sufficient torque to the mount it can, I've found, muck up a carefully aligned mount. I tend to avoid rotating it if at all possible. When I first set up I tend to scan the mount and telescope about to the different parts of the sky I'm interested in to make sure I can reach the eyepeice. Then I align the mount.
  18. I usually have to slacken off the rings so much that there's a risk the scope will drop backwards unless placed horizontal. Worse than that all the pulling and pushing has either misaligned the polar alignment or shifted the RA or DE axes despite having the clutches being tightened up. I must say that apart from imaging this is one of the main reasons I have stopped using my reflector for visual.
  19. @woodblock It's one reason that I enjoy using my refractor. The eyepeice is always accessible and can b rotated to a more comfortable position if necessary. I've never done this but I know that some people buy and modify another ring which sits tightly around the scope tube but isn't connected to the mount. This third ring then rests back on one the 'proper' scope rings. The scope can then be rotated within the lossened scope rings without sliding out of the rings. I hope that makes sense. Someone might have a photo of such an arrangement.
  20. Could we amateurs crowd fund a resurrection of Ronald Reagan's Star Wars project. Zap zap zap zap zap.....
  21. What have professional astronomers said about this? Anyone know?
