  1. Ya know, I read the title as "Oil Filter" causing me to say, 'What the hell?'
  2. That's wise. I don't trust my expensive equipment to my drunken hands either.
  3. Caught Jupiter last night with my freshly collimated scope. Even at 300x I had a good view of the NEB, but could not make out the GRS. Got to watch Ganymede disappear behind the planet. Quite possibly the best views of Jupiter I've had through my own scope.
  4. Get a collimating tool, which you should have anyway, put it in the focuser and check against the instructions to see how well lined up everything is. You will have to collimate your scope at least a few times a year. Astro Baby's guide is probably the best I have ever seen for a beginner. If the stars are not focusing to points, you probably need to collimate. Poor optics can cause problems with focus too, but Skyliner is usually a decent scope.
  5. Remember that the more powerful your binoculars, the more sturdy your mount will have to be. I have a monopod that I use with my 10x50s very well. I think it would be ok with 15x binocs, but I put my 30x spotting scope on it, and it's impossible to hold it still enough to see owt. This means that the price of the whole system will go up exponentially as the binocs get more powerful. But, you probably know that already. I can get as low as 20x if I wished to with my refractor, and aiming it and holding it steady would be easier than with a pair of binocs.
  6. Between about 9 and 11, usually, as I have to be at work at 8 AM and capable of making coherent sentences. If there's something amazing happening, I have been up as late as 12.30 on a weeknight, 2AM on a weekend. In summer we get decent dark after 11.00 so I don't have to be up after midnight to see something.
  7. You can certainly do moon pics through this scope. You may find the mount a little light for holding up a camera as well as the scope, and a bit wobbly besides. The tracking motor they sell for these mounts works very well. You need only the RA motor. I bought the declination motor as well but have since disabled it. However, I think long tracking is asking more than this mount can deliver.
  8. St. Catharines, Ontario, Canada, and the marker is about 100m from my actual home. Glad to get it placed at last.
  9. Friday and Sunday night I put my scope out for a look at Jupiter. Friday I was using the C6N. The view wasn't quite what I wanted and I wondered if the scope might need collimation. I took a look down the tube in daylight though, and it looked perfect (realized later that I had made a fundamental error in my assumptions about what I was looking at.) I'll put the collimation tool in the focuser later on today. Sunday I started with the reflector but quickly switched to my 105mm refractor. At 208x I could clearly see the NEB and the south polar region as I watched Europa drift slowly away
  10. Not exactly. It is a 100mm aperture, and if you follow the formula I give, your ep will give 133x no matter what the focal length is. If you have an f/8 scope and are using a 6mm ep, then 800/6=133. For the f/10 scope, 1000/7.5=133, and for an f/6 scope, 600/4.5=133. This result surprised me a little when I was putting this article together. Thanks to everyone for your kind comments. Family matters, health and work have kept me away from the ep and from the forums this year, but I am planning a resurgence.
  11. THANK GOODNESS! I'd tried four or five times and I certainly wasn't going to try 136 times in this life or the next. I'll wait until I hear...
  12. Don't know if I mentioned it earlier, but I have a 11/5" f/6.2 mirror to make into a dob. I'm planning to use 3/4" birch ply for the base and mirror box, maple dowel for the struts, and laminated birch ply for the top end. Should be fun.
  13. Not in the dual drive kit, Chris. The RA motor attaches via a sleeve and set screw, but the dec motor has a clutch that allows you do disengage it to allow for manual adjustment. I saw a picture of a single RA drive for an EQ-5, which had a clutch, but I don't know if that is available on the EQ3-2 RA drive, or if they just showed the wrong picture. Thing, I'm thinking about that!
  14. Thanks, as it turns out, the moons I was seeing close to the planet were Titan and Rhea, and the two objects further away were stars.
  15. Just at sunset last night, with the sky still quite blue, I could see that the view of the Moon was unusually clear, and once I got the scope on it, it did appear to be very sharp, and the seeing was fabulous, even if the transparency wasn't much to write home about. I started out with an 8mm Celestron X-Cel (125x in my 105mm refractor) and soon switched to my 4.3mm Antares W70 (233.3333 x, OK that's pushing it a little, but in skies like this it pushes well.) I didn't bother to bring my moon map out with me, so I just gawked at the wonder of it all. I was able to catch Mons Teneriffe,
  16. A couple of years ago, I motorized both axes of my EQ3-2. This does a wonderful job of following objects (I should mention that I am a visual observer, the dec motor may be useful to photographers; I don't know,) but I often found myself undoing the clutch on the dec axis to position objects in the FOV without waiting for the interminable 5 second lag before the motor caught the gear and started moving at a glacial 2º/min. I used the dec motor for a long time to move up and down the Moon, but nowadays I just leave the clutch loosened and do all my dec adjustments by hand. If I have to replace
  17. Scopes don't generally deterioratee with age, except for getting dirty. Your scope is probably an f/6, which will be a little more forgiving that the f/5s that are the usual today. You should find it a very good scope once you get used to it. Buy branded plossls, and you can't really go wrong, but consider saving a lttle more and getting wide angle eps with better eye relief. They will give you a better view. You should have lots of fun with that scope. Oh, buy a copy of a current astronomy magazine, as they all have decent star maps and articles on what is visible at the present time. Get a r
  18. I have a 6" reflector and a 4" refractor. Both give good planetary and lunar views, with a slight edge to the refractor. I generally suggest that a beginner consider nothing smaller than a 90mm refractor or a 5" reflector, and bigger is better, all things considered. I use the refractor when I am planning to go out and look at the Moon or planets. When I am going to look at clusters or nebulae, I take the reflector. In any observing session I may look at the other type of object, more or less successfully. I find the reflector more comfortable to use. What I mean is that with the ep at the top
  19. Once when I posted a picture of my scope, someone told me I should mow my lawn!
  20. Interestingly, that's exactly what the Palomar scientist, a Finnish astronomer named Loof Lirpa, was saying about it.
  21. Ah, right! We couldn't see it up here.
  22. I took my lovely Springer bitch out for a pee last night before I turned in, and noticed that Betelgeuse looked unusually red to the naked eye. And I caught a bit on Discover's Daily Planet show that Palomar scientists are watching for the possibility that Betelgeuse may produce a supernova in anywhere from days to weeks. They say we are far enough away to not be seriously threathened, but it should produce quite a light show. Mmmm. Betelgeuse in daytime without a telescope. Should be fun!
  23. I bought a pair of cheap but decent 10x50s a couple of years ago, and have taken them out for stargazing a few times (I bought them mainly for terrestrial observing) but found the shaking difficult to deal with. I have a light camera tripod, and bought an adapter and tried to use the binocs with it, but found it limited in several ways. It's a bit too low, and shaky, and actually difficult to point, as it doesn't move smoothly, and you have to look above your subject before locking the azimuth swivel, so the binocs will drop a bit when you let go of them. This meant that I couldn't look at a l
  24. Sure enough, God put the Moon back, and Venus. I got Venus in the scope, but it was a blurry disk in the sunset glow, so after a minute or two I put the scope in the Moon. About all I could see was that Mare Crisium was fully in sunlight, but the view didn't appear very satisfactory. I came inside to let it darken up a bit, then went back and tried again. I wasn't able to come to a decent focus with any combination of ep and Barlow, so I stepped back a moment and then took another look. I realized then that the limb of the Moon was waving like a flag in a force 9 gale. That was good because I
