  1. Area wide blackout for nearly 3 hours last night. Just my luck it was raining Would have been the perfect time for observation and imaging.
  2. I have noticed from reading through this thread that one of the main reasons you want a tripod is in case you have to move it around. Now i'm curious do you mean move it around as in into and out of the house/car to go viewing or do you mean move it around while viewing. if you mean the former moving a dobsonian to your viewing location is not that hard and the 200p should not be that heavy. Now if you mean the latter then I am afraid you are mistaken, if you think you will need to move it around the garden when viewing then you definitely don't want anything on an EQ tripod mount as you would have to go through the polar alignment procedure every time it gets moved even if it's only a few inches. I own a scope on an EQ mount and there is nothing more frustrating than viewing from your back garden and deciding hey lets look at XX and realizing next doors tree is in the way, it's just not worth the hassle to move the scope in that instance. So that said even though I don't own a DOB I wish I did and I would recommend that route.
  3. I'm currently trying to locate a piece of dovetail bar that fits the mount for my Astromaster 130EQ. If I can locate a piece then I can actually put the camera on the scope mount and use the motor drive to reduce it. I could just piggyback the camera on the scope but for portability sake it would sometimes just be easier not to have to lug the whole scope around
  4. Thanks for that, I always shoot at the widest setting for my lens but even then above 5 seconds makes trails and I can't go anywhere near the 22 seconds that formula states. It does not seem to matter where in the sky I point it's always the same.
  5. At risk of reviving an old thread I am very curious how you guys are getting such long exposures with 18-55 kit lenses on camera tripods. I use a Nikon D3200 with a 18-55 kit lens and anything over about 5 seconds and I get horrible star trails if I were to attempt the 30 second exposures you guys are doing the trails come out about a quarter of a cm in length. I set my lens at it's widest field to try and reduce the effect and I shoot at ISO 800 with my f.stop 2 clicks back from wide open
  6. I would but my tripod does not have a level built in I carry a small spirit level in the box
  7. OK thanks for that I move my scope around to different site so making permanent marks is not possible. What I was doing was carrying around a long straight edge that I would align on the ground using the compass, this created a perfect east/west line then placing the two back legs against the edge would align the front leg north. This is a bit of a pain though because my entire scope fits nicely into a large plastic box that I use to transport it encased in foam but the straight edge did not fit and was a pain to carry with the box. But now I know roughly north is good enough I won't bother with the edge anymore.
  8. How important is it for this to very very accurate? I realize the mount sitting on top of the tripod has to be pointing properly north and this in not hard to do as I have a flat surface on mine to rest the compass against. But on the tripod I do not have a handy flat surface, I can use the bracket at the top of the leg (legs are not magnetic) but I cannot be 100% sure this is bang on north. Will that be close enough or does it have to be exact? Like I say I can rotate the mount on the top of the tripod to get proper polar alignment anyway.
  9. Had a wonderful cloud free night last night and managed to capture this. Not the clearest pic as I just help my phone up to the eyepiece:
  10. Just the original Celestron red dot finder which is about as useful as a screen door in a submarine. I have read that a lot unfortunately I have to make do with what I have because I can't afford to spend any more money one it. It took me over 2 years just to save the cash for the scope itself. I realize Telrads are not that expensive but it's just too much for me.
  11. Depends When you go and look at tutorials a lot of them say the back leg should point south. Another video I watched today had it pointing north. So it can be done both ways apparently. Surely the position of the tripod legs is not that important, it would be which way the mount on top of it is pointing that would matter.
  12. yes but if the mount is pointing stright at polaris so is the telescope
  13. Because Polaris is at a right ascension or 2h 30m so when centered if you manualy turn the RA scale to 2.5 or 2h 30m then your RA scale should be aligned correctly. I don't know why you brought time into it as time has nothing to do with RA and DEC those numbers remain the same for any given object no matter where in the world you are or what time it is. for instance Vega has has a RA of 18h 36m and a declination of +38 degrees 47 minutes. and a properly aligned scope with acurate RA and DEC whells set to those coordinates would be looking at Vega, it would not matter if you were in Paris or Sydney the numbers do not change. Time only comes into it if you are using a Alt/Az mount.
  14. I had already read that a couple of days ago and since that review states that alignment is "quite and easy process" it just makes me feel even worse since I can't get it to work.
