  1. I was a bit worried about using the eqmod, but in the end it wasn't hard - just finicky... like all PC stuff the input has to be correct or it doesn't do what you want.
  2. That fan behind your head looks dangerous.... Sometimes a jet can pass in front of the lens (well between you and the target anyway) and the con trail will keep the view messed up for quite a long time. Betelgeuse is kinda neat huh? Amazing colour and size. Try looking for a globular cluster - they're amazing to look at in even a modest scope. Not sure which ones in the Northern hemisphere are cool as I live Down Under.
  3. This floored me until I realised that the end of the sentence qualified the beginning and should have been started on a new paragraph. So ignore the syntax on that article and extract the good intentions. Good intentions which I find a little unrealistic, I'm sad to say. Enthusiasm is one of those things that makes and urges us to make, instant decisions about what we want. Telling us to go to the library is going to make us stop reading the article almost immediately. I'd say, to be fair, that most people make the usual error in buying a cheapy "to see if they like it" and end up even more frustrated because it is awful to use and of awful quality. My advice? Go to a club and ask someone what they recommend. They'll only be too happy to indulge you with their unique perspective. Tell them how much you want to spend. They may well say they have something that they started with and will loan, sell or give you said machine. Go to a proper telescope store (not National Geographic or similar stores that stock mostly toys with pretty pictures on the box and x750 claims of fantasy) and ask the owner for a rundown. He isn't going to stock rubbish and he wants you to come back time and again to buy the next level as your knowledge and interest increase as they usually do. Go to the library sure, but don't become a recluse trying to learn the universe from your suburban backyard, because you probably can't see much more than a sky lit with a million HP Sodium lights and maybe the main constellation stars (sometimes - if it is clear and cool).
  4. Alas buying a scope is like buying a car, do I get a people mover, sports coupe, sedan or 4x4? Do I go cheap or luxury? Do I get all the bells and whistles? There are more bits and pieces designed for different parts of the hobby than there are types of flying insect. I suggest trying out one or two at a local star club or something before you go off and spend money on what may become the Ancient Mariner's rotting carcase round your neck. General rule is you can't photo using an alt az and you can't buy cheap gear and expect amazing pics. Both rules are easily broken by luck but not by judgement. Best wishes
  5. I have to admit that it' the one thing I look at just about every time I turn on my kit. Except of course when it is not visible before 2am! We are actually part of Orion arm in the Galaxy so we're considered to be quite close to the nebula - there's a few things worth looking at thereabouts but not all visible in small scopes (less than 10") It's a wonderful way to start off your Astrophotography once you get some capable kit. You can of course do quite a bit with minimal kit but it can be frustrating. Hence the catalogues with ever better mounts and cameras. Most of which none of us will ever be able to afford. This is about what you'd see through the lens with most scopes up to 10"
  6. point the mount axis (not the scope) at the pole star and go from there
  7. Sometimes it's the obvious we miss. I had the same thing on my NEQ6pro and found it was the connection to the power supply - it lost track of where it was because the connection limited the throughput of watts. Cleaned up the cigarette lighter socket and it worked fine
  8. Odd, my lx90 is bog standard and there isn't even any backlash never mind flop. I can adjust my focus using x10 on APT and a batinov mask - which equates to 800x - without the image shifting more than a few pixels.
  9. The isopropyl alcohol has difficulty staying on the tissues out in space so I'm not going to clean it EVER
  10. Sigma Octans is the proverbial needle in a haystack. Except there's no needle and no hay. I can see it on a clear night in the polar scope, but any crud in the sky and don't bother. Have to admit I only did it once then marked my mount as it is on a pier. This weekend I'm going to a different site so I'll be using it again if it's nice - though the forecast isn't good.
  11. Quite correct lukeskywalker. Clever you are. Ask the wife you must mmm yes.
  12. Formula is focal length over the diagonal size of your sensor equals magnification. There is no light lost in the use of smaller diagoanal or adaptor.
  13. Or mount your ota on the mount with your gt81 and use one for guiding and one for ap. You can swap to either no problem. see pic

    Never would have believed it. Well done
  15. My mains pipe is 250mm dia
  16. The stars in your piccy show two things, one is a small amount of coma towards the bottom. This is usually caused by the focal reducer not being at the right spacing for the sensor to focus correctly at the edges - or the wrong reducer for the telescope which sometimes happens Further up there are triangular stars this appears to be a small vibration - maybe caused by heavy feet or a caught cable. If the stars are triangular, it could also be a pinched mirror - that is the edges of the cell are too tight and forcing the mirror into a slight distortion with three lobes - hence the triangle stars. If you haven't been messing with the cell, I'd say vibration.
  17. There's a wonderful feeling when suddenly it all comes together. This is how I connected mine when I first got it going
  18. Remove the rubber eye ring then as above, insert into wide tube. The nice thing about using eyepiece projection is the magnification can be upped amazingly.
  19. The biggest problem is vibration - make sure you are settled and the tripod is nowhere near your feet!
  20. I did the same thing. Though my top plates are a touch more substantial at 15mm steel. I dug down about 800mm in what can be described as Devonian rock about 800mm and about 700 round and dropped a shopping basket (steel mesh with a hole in it onto some bricks laid in the bottom in the basket was a holewhic the plastic pipe entered into a short way. Four reo bars were put in the tube and it also had 4x4 inch holes cross wise which had 600mmsteel through them which rested on the shopping basket. Fill with concrete and place top plate with j bolts under draped into the concrete before it sets a few taps on the side to settle and allow to set. It is totally vibration null. My deviation isn't measurable when I slap it. I can adjust my focus in live view without the mask live view x10 (x400 in real life as the base magnification is 40) moving. All in all it's a very sound design.
  21. The periodic error cycles around the same point whilst drift - does exactly that. It is an angle across the sky as your RA progresses. If the same stars are visible in your pics after 6 hrs, the drift is quite small as the usual angle of the pic is less than 1 degree - that's one degree in 6x15degrees of RA. If you can see how much it has moved, could be a good move to adjust your dec bolt by half the amount and try again!
  22. that's why bumpers on cars are now plastic coloured the same as the car and VERY expensive. I have a blumming great stainless steel bar across the front of my Ute
