  1. The motors for the mounts are completely different. The EQ2 has a chrome gear wheel which is driven by the motor while the EQ3-2 motor attaches to the RA and Dec shafts. Mike
  2. I just ran the program - sorry Eccentric but you missed something. The circle represents the field of view through the eyepiece but you do not look at the eyepiece from a foot away (as you do a PC screen) but with it against your eye. If you look at the simulator again and put you eye much closer to the screen so the edge of your field of view can just see the circle - now Jupiter will look bigger. This is how it will be in reality. I was looking at Saturn last night at only 50x and it was easy to see it and the edge on ring. Saturn is only half the size of Jupiter. Mike
  3. The moisture causing the problem is more likely to be coming from your eye not your mouth or nose unless you are breathing out as you approach the scope. Mike
  4. Probably the biggest difference will be the smaller size and wider field of view of the image in the Konus for the same size EP. Your Mak has a focal length longer 2 1/2 times which gives a higher magnification. I think you will still prefer your Mak as the stars will be sharper. The slightly bigger aperture of the Konus should not have that much of an effect. Mike
  5. Welcome to the forum . Mike
  6. Welcome to SGL Nothing like a big scope to get good views. Certianly a 10" will show you just about anything you are likely to want to see. Have a look at the free planetarium programs like Stellarium (www.sellarium.org) or Cartes du Ceil (http://www.stargazing.net/astropc/). These will show you where more deep sky object can be found, there are plenty at this time of year. Mike
  7. I would leave the mirror alone unless it is so dusty you cannot set your own reflection in it. Soap flakes and water are all you should use. The mirror should be removed to clean it. Mike
  8. I have the same scope and wrote this review which might help. http://stargazerslounge.com/index.php/topic,35242.0.html The barlow lens goes into the focuser first then the eyepiece, this doubles the magnification of the two eyepieces. A couple of pointers: Align the finder scope in daylight on an object about 1/2 mile away if you can. You can check it against the Moon when you satrt observing. Use the eyepiece with the largest number (it represents the focal length) first as it will give you the lowest magnification. Easier for locating your alignment stars. When aligning on a star get it as central in the eyepiece as possible - it will make the GOTO work more accurately. Mike
  9. Welcome to SGL Mike snow free still
  10. As the SCT has a narrow field of view I would recommend wide angle EPs. A 32mm, 12mm and a barlow (if you don't have one) would give you a range of magnifications from 47x to 250x. The wide angle EP will give you a much larger FOV than equivalent Plossls. Mike
  11. Was up at 05.30 to catch comet Lulin before the Moon messes up the viewing. Bit of thin cloud to start with but that soon went. All the Summer constellations visible. Thankful for the observatory keeing the freezing wind off me. A satellite pic on the new last night showed Galloway as green not white like the rest of the the UK. Just off to make the wife a cuppa. Mike
  12. First view of Lulin this morning. The sky was clear but between the Moon and approaching dawn it was not very dark. The view through the 10" f6 dob showed a large fuzzy ball about the size of M13 with a faint star like core. Lulin has arrived at a bad time as it and the Moon are approaching each other. They will not be separated enough until 16th Feb. The comet will be much brighter by then. This is the 30th comet I have observed. Mike
  13. Welcome to SGL from Scotland Mike
  14. Its one of the disadvantages of the Plossl design. The short focal length EPs have terrible eyerelief. A 4mm is even worse than your 10mm. Skywatcher do a range of long eye relief EPs which are reasonably prieced. http://www.opticalvision.co.uk/astronomical_accessories/eyepieces/sky-watcher_long_eye_relief_ler_eyepieces If you use a barlow lens you get higher magnification but the EP eye relief remains the same.

    Hello Everyone

    Welcome to SGL Definitely go along to York AS, no need to worry about a lack of knowledge. Mike

    hi all

    Welcome to the SGL another Mike
  17. Definitely worth being friendly with the neighbours. When I lived in Bradford mine they fine about turning off external lights when I was out with the scope. Now I don't have to bother they are too far away. Everyone knows what we do as there is a big sign outside the house! Nice pic Carol. Lots of snow, still no snow here must be the only place in the UK. Mike
  18. Welcome to the forum and welcome back to the hobby Mike
  19. Welcome to SGL. Would thoroughly recommend joining your local astronomy club, if it's not to far away. Mike
  20. You would need a microscope to see the snow on my observatory. The distant hills have caught it all first Mike
  21. Hope it's clear for you soon. Have a look at Venus in the South West. It should look a similar shape to the Moon. Mike
  22. Hi Dom welcome to SGL. If you are only interested in visual observation not imaging then a 10" reflector is just what you need. The Skywatcher reflectors are well made, I have used several of the solid tube versions and all of them gave great views. Posts on SGL gives good reviews of the Flexitube too. Useful extras would be a 32mm wide angle eyepiece as it will make finding objects a little easier and show more of the larger ones. A variable (polarising) moon filter which will reduce the glare of the Moon. Happy 40th in advance. Mike
  23. Welcome to SGL. Well done for finding those objects already. Mike
  24. There is so much choice it is hard to know what to do. The 200mm Dob would be a great visual all rounder but as you say not great for photography except for the Moon. I assume that the same scope on an a driven equatorial mount is outside your budget. With Maks and SCTs dew collects on the front corrector plate not inside - provided you cover the visual back before bringing the scope inside. The mak127 is a great planetary scope but the supatrak mount will not allow for long exposures. Mike
  25. Hi Dawn welcome o the forum One point I don't think anyone else has mentioned. You need to remove the whole of the cover from the front the scope. Some newbies only take of the smaller one in the centre. Mike
