  1. Looking forward to seeing this progress, it's about the size of what we could accommodate if ever I'm lucky enough.
  2. I gathered that, it just made me chuckle. I'll shut up now and let someone with a dob answer.
  3. Mine's lovely and smooth, but it's not a dob so I can't really compare. I fitted a motor to mine though and you can disengage that so it's just a 'manual' again, surely you can do the same on the dob. You're undoing your locking knobs etc before manually slewing? What about Nearly dead aging farmers Darren?
  4. I don't have a goto, but I know at least some of the hand controllers have a speed control, could you not get it in the general area and then set it to the slowest setting to alleviate the clunkiness and fine tune your view?
  5. I assume you mean the one facing us in this image, that's just the lock. You use the one at the rear (left in this image) to 'set' the position, the head sits on that, then you lock the position using the one on the side.
  6. You use the lever to engage/disengage the motor for manual control by pushing it away from/towards the large wheel on the back of the RA axis. That's assuming you've got the fancy motor that fits on that side, rather than the economy one that fits to the other side of the mount.
  7. The only suffering I've done for the hobby so far is falling asleep thanks to too much malt or home-brew prior to or during a session. Quite embarrassing if anybody knew....... ahem. Plenty of difficulties and things that were hard to do but nothing I'd describe as suffering. Speaking of malt, have any of you Laphroaig drinkers had 'non chill filtered' Laphroaig. A completely different drink and probably the start of a whole separate discussion I suspect.
  8. It's a clutch for the multispeed RA control, it you don't have that you can ignore it.
  9. Signed by me and The Present Mrs Foster. that's 115. Also put into the Twittersphere, not that it's likely anyone pays attention to me
  10. Halley's observation notes for the transit of Mercury in 1677 from the Royal Society archives, and the reflecting telescope built for the 1st of the pair of Venus transits in 1761, the one before the one James Cook observed. lovely bit of kit. I love this Youtube channel, well worth subscribing.
  11. I'm certainly finding a growing need for a RACI, just for the convenience, especially with a newt on an EQ, it means I won't get muddy ears and a crumpled coxic. The optical finder obviously is harvesting photons, allowing you to locate with fainter objects than the RDF/Telrad. I believe the generally preferred method is to get in the general area with RDF/Telrad then fine tune with the optical finder. In fact I shall probably be pulling the trigger this week, model yet to be 100% determined - I shall look at the GSO Dave, what is it that particularly pleases you about it over your other models?
  12. Welcome, and the family and Hector. I had a similar experience. I learnt so much lurking around these parts I just had to join the fun. Those fruitless nights are a great opportunity for a bit of fettling with the gear, reading up and other 'theory based' activities. You'll never lose the passion once you're hooked. And I too am sharing with others, a ten year old niece in my case who is taking every opportunity to get out observing!!

    Hi all

    Put the telescope down, step away, turn around and walk away, or call the official receiver, that's a slippery slope to bankruptcy there sir. Welcome to SGL Matt, they're an awesome bunch of folks here and from my recent experience I cannot recommend enough that you ask as many questions as you possibly can, so much knowledge here it's amazing.
  14. You're a braver man than me, but looking at the data column definitions you want the data from the column 'st_vmag†' for your given range. Unless of course I'm wrong..... It could also be 'st_mbol' if you want bolometric magnitude or any of the 'st_wise#' columns if you want the 2MASS or WISE photometry data. I'm certain there are also other routes. I'm rambling, Ignore me, I'm basically asleep, and Patrick already said this.
  15. I can vouch for that, had my intro to GCs recently with M13, in cracking conditions and now have the bug myself. Ruddy clouds have scuppered any future efforts though. I've got half a lifetime, or more hopefully though!!! "To me it's as much about what you are looking at as what you are seeing" And that's put more eloquently than what I said, in that it's about what you know as what you observe. Just to find out about what's happening up there in that little blob, or fuzzy area, incredibly rewarding, regardless of the quality of the views.
  16. That's stunning, I'm almost more drawn to that AR than I am to Mercury.
  17. Brilliant work. An excellent demonstration of what can be achieved with a little (or a lot) of patience.
  18. That's lovely, love the detail in the dust lanes and the dense star areas on the arms, the redo definitely brings out more of that. Not bad for 'rusty'
  19. Agreed, Ravenous said "But maybe the first step is more unlikely than people think" Unlikely isn't really a limiting factor on a cosmic scale, even locally on a geological scale - hence evolution. Stars are born given the right conditions, and that happens in the billions of billions, stars have planets in their droves as we're starting to see thanks to Kepler (1284 planets so far I believe) etc and so on. Obviously none of this is evidence for life elsewhere in the multiverse but it's compelling enough to make it worth looking and supposing and imagining, surely.
  20. Lovely presentation - did you go looking for that or was it a chance opportunity?
  21. What I found worked for me with a very ropey old webcam Craig was to lower the exposure all the way down, take the Gamma all the way up (I'm using sharpcap, but I'd imagine you have the same settings if you're using different software to capture) stir in some contrast adjustment to taste and increase the sharpness but not too much. Didn't need to adjust anything else. I don't know if that'll make any difference to you, but for me it did. I captured about 2-4k frames at 30fps each go around (the limit for said cruddy webcam) and I managed to massage the results with Pipp, AS!2 and Regi to get something that was vaguely recognisable as Jupiter, even got some moons on one of them. Best of luck and clear skies. Forgot to mention 2 things, the first time I did this it definitely improved the darker it got - I started quite early during twilight. Also, assuming you're on a lappy to drive the cam, check your screen angle. I don't know if it's because I'd had too much home-brew or something, but I definitely noticed that if I tilted the screen towards me, so that the rest of the display started to become not optimal, the detail improved on the planet live view.
  22. Just WOW, had to double take to make sure I'd read the words 'pastel drawing' in your title and I'm completely not blowing smoke up your wotsname. That is a great piece of work, get yourself down the Tate sir.
  23. beautiful, lovely crisp disc on those closeups. Well done.
