  1. I often find my CG5 can be miles out on the first alignment star and even on the second - upto a couple or so degrees perhaps - I just manually slew it onto the desired target and carry on. By the time it gets to 1st or at most 2nd calibration star its generally spot on. Doesn't mean, yours is ok of course. Are you remembering to select Standard Time as opposed to Daylight Saving Time? It wouldnt be the first time that I have forgotten that one :-)
  2. Not sure given the speed issue that Hyper' mentions but perhaps these? BBC News - Mount Etna mapped by radar satellites
  3. You can query the SIMBAD database SIMBAD Astronomical Database and select either the basic or identifier link - enter the HIP identifier in the field (include the letters HIP) and it will give you a page detailing the object - including several different identifiers if known i.e HIP, SAO etc.. Thats how I have done it in the past in an ad-hoc way. I dont know of a method or plugin to allow this directly from Stellarium.. of course I havent checked to see if there is an SAO catalog available for stellarium which might be a better bet long term...

    orange lights in sky

    Most probably chinese lanterns Joanie - it seems that they are becoming an increasingly frequent phenomenon.
  5. The University of Rochester seems to think it has resolved () the issue... First known binary star is discovered to be a triplet, quadruplet, quintuplet, sextuplet system First Known Binary Star is Discovered to be a <strike >Triplet</strike>, <strike>Quadruplet</strike>, <strike>Quintuplet</strike>, Sextuplet System : University of Rochester News

  7. Orbit? I reckon im Class 6 here According to TimesOnline here: Galloway Forest Park: one of the darkest places on the planet - Times Online talking about Galloway Dark Sky Park (Borlte 2)... "Bortle 2 is as dark as it gets on dry land; only in the middle of the ocean, where light pollution is entirely absent, could you experience the profound blackness of Bortle 1"
  8. Tethis was close to Enceladus last night - making another combined point - I managed to see both (pairs - i couldnt split the four moons) with my C8 @ about 100x (I was using a focal reducer) - ramping up the power to 200 failed to resolve the two pairs. Maybe there wasnt just enough light for the 6" to grasp - they were pretty faint to me.
  9. Just kill the power and start again? - The polar alignment is mechanical so it will hold through the power off and when you power up it will be nicely polar aligned and automatically drop into the start up and 2-star alignment procedure no?
  10. I have never done the full polar aligment on myc CG5 that you have old_eyes - but by my recollection the manual does say that you have to do a full sky alignment again after the polar align routine. Strictly speaking I think that replacing the two alignment stars ought to work but I would be inclined to think that the whole schbang is the way to go as implied by the manual. At the moment I am strictly visual so it isnt really necessary for me to do anything other than plonk the thing down roughly facing north and more or less level, though I do sight Polaris through the boresight and get the bubble in the circle which is usually easy enough (I have marks on the tripod extenders to get the length right for my usual obs position). I usually always take all four calibration stars too (it helps me learn and remember the sky lol)
  11. Funnily enough I got that last night. I mistyped an NGC number and the scope slewed to somewhere near Argentina, realising my mistake I reset the code but foolishly didnt wait until it had stopped slewing - so it whirred and clanked to some new rubbish position and then paused and started again when I physically touched the OTA - I didn't connect the two at the time (silly boy) and then it stopped with the above error. I sighed and reset the tube manually to the index positions and chose the last alignment option hoping to pick up where I left off but when it 'stopped' slewing to my chosen M35 the tube was still pointing more or less at the CNP As it was near the end of my session I couldnt be bothered to re-align and decided to pack up for the night. As I was doing so I realised first my second mistake - I had forgotten to re-tighten the RA clutch when I had manually reset it just a few moments before duh - no wonder it didnt go far lol And then as I was dismantling - when I came to remove the DEC motor cable instead of having to faff around with the damn silly little tab the thing just fell away in my fingers - explaining the No Response error - sheesh my earlier mistake had been not checking it was plugged in properly from the start! What can I say really - obviously I was taking stupid pills yesterday. Oh well at least I got a few nice views in before the idocy made itself known lol and there were no witnesses to my witlessness :)
  12. This object is no where near Orion - it is in a region about midway between NGC 2281 and Psi 2 Aurigae according to the co-ordinates given. There are a couple of redish orange stars in this area with apparently close companions. My first thought here was HIP 32433 but I wasnt able to reconcile the nearby star patterns with the video stills. Another candidate which is less orange but where some nearby star groupings look similar is HIP 32152. Google Earth/Sky has missing image for the exact co-ordinates offered, which doubtless fuel the conspiracy theorists. According to an earlier posting on the comments on UTube the videoer I believe stated that this red object was visible to the naked eye - but I couldnt see it thats for sure when I was out the other night - and I did look for a bit of fun. Though I didnt point the tube thingy there. Anyway I am unqualified to comment on the whole brown dwarf thingy etcetera but its fun to try and identify what someone else has seen and not been able to identify themselves. All that having been said if he got the co-ords from an LX 200 then they will only be as good as his alignment I suppose...
  13. Price excludes Taxes, Duty and Shipping, quite apart from riklaunim's plastic comment... TAL 3X from someone like FLO seems a safer bet - I know I'm pretty happy with mine (TAL) :-)
  14. The same RDF is sold under a number of brands. I have one - a revelation - it is a repurposed gunsight. I dont think it has concentric circles - that is a cross with a circle superimposed or a dot with the same and I have no idea what view angle the circle(s) encompass. It is petite and functional if you want to slug the scope onto something you can see but little use in my experience for finding anything that is not visible to the naked eye. I think mine costed around 30 odd quid from Telescope House if I recall. I got it to fit on my little meade ETX 80 cos the telrad would have been bigger than the scope! and primarily to help with putting the tube on alignment stars. I have found that since I got my clestron c8 I use it much less and have resorted to the finder which is much easier to use than I anticipated, although some times I do still use it to point the scope or as a 'marker' to see where in the sky the tube is pointing without having to deal with the upside down back to front squint my eye finder scope :-) It has 4 different reticules, a fine dot, a coarse dot a cross and the cross with circle. And 7 brighness settings. I usually use the bare cross and the lowest setting is fine for brightness. It is still low profile and effective given its limitations - i.e. no graduated circles like telrad or orion. If you just want to put a dot on something its good enough - if you want to systematically find a target in the middle of a blank patch of sky by walking 4 degrees then half a degree then you are out of luck I'm afraid.
