  1. So I made myself a very solid latitude bar 2" steel, andcreated q new site with the correct settings.setup with handles upwards as advised for the LX90 and first time alignment worked perfectlt, at last So now I have just one issue left, and this is down to me. How do you ensure that your OTA is pointing exactly 90 degrees to the forks.latitude and azimuth adjustment is simple.buy I get it all looking 100% spin the OTA as and polaris flies off sideways. The diwc on the fork is useless, it's been moved. Is it just hours of trial and error then set the fork indicator or is their an ea
  2. Very similar to mine except I have a bubble level instead of a compass and I am missing items 4,5 & 6 from fig 3. Or item 4 from fig 1, plus the latitude control is also missing, that's easy to work without but the fine azimuth control is impossible, the OTA is barely held anyway by the adjustment knobs without that bar to support it and in addition supporting the whole weight of the scope while looking through the eyepiece while trying to make mm adjustments and tighten down is close to impossible I am trying to make one from drilled/threaded aluminium bar and some epoxy weld.
  3. Thank you, so I guess I have the basic wedge, missing that bar, I'm going to add it as trying to adjust without it is impossible, basically you have to loosen off then support the whole scope with your arms while looking through the eyepiece then tighten, any small adjustment is impossible. The alt adjustment is fine, just undo the support a little bit and move left and right so I'll just leave that. I have checked the scope model, and don't forget it's perfect in alt/az checked the mount 100 times:) and haven't tried a 2 star alignment, but then if it can't find a star from the easy or
  4. And damn, last night was a complete write off, I've just contacted Opticstar who were very helpful and going to look into it for me. This is my current situation, I can't try again as my wedge for some reason doesn't have the azimuth control so I have to hold the scope undo the screws and move it while trying to look at the eyepiece then do them up without moving it, nigh on impossible I found last night, so I am going to make the Azimuth fine control and add it before trying again. My telescope is approximately 10-13 years old and is an 8" LX90. I have added the LNT device to it a
  5. I've finally sorted it. everything is perfect in alt az and the battery pack I use is a 13500ah that also runs my PC last over half a day running the PC and the scope:) However I use starpatch for gps.on my handset it all looked good when it gets the GPS reading, but after about 20 attempts at polar alignment I noticed that the time was jumping ahead exactly 7 Hours even though gps showed fine. Disconnected the GPS and the lnt and set the time manually looked a little better but not good but at least time was correct. Then I deleted the site I had created for my location, rebooted wi
  6. So that is the OTA pointing due south, at 0 degrees? and forks parallel to the ground and pointing north? I like cables mines as bad especially with the mini PC attached to the Forks and the battery pack on the opposite fork.
  7. I would appreciate that yes please. Especially as mine doesn't have the azimuth bar for fine adjustment or anything missing either, just not there. Ah, dst forgot that, is that a setup setting? It just confused me auto selecting out if view stars. I am only testing in daylight but it should know that? But dst I forgot!!! When you say controls towards north the lx90 controls are in the fork arm, not the base, so shouldn't the forks be parallel to ground? If needs be I can try the south at 0 too. Couldn't be any worse, lol. Just to confirm again though, polar home setting sco
  8. So do you not do any of the autostar alignments? I have noticed if I do it like this then if I press the mode button for a few seconds then the readings are not at 90degs and 0 but any random numbers, or do I need to turn it off and back on again after setting polar home so they reset? Just to be certain, at polar home the ota should be pointing at eight angles to the base and wedge directly at polaris and the handles and finder aiming towards the ground. Time and date is from gps using starpatch plus I also have the lnt module added. In alt as it all works perfectly, so I
  9. So I have an LX90 fork mounted with Meade wedge. Setting the wedge correctly and setting polar home so Polaris is at the center of thecwyepiece with handles and finder painting down. 1 star align with Polaris seems fine, then slews to several stars below the horizon. I can't find any instructions, my manual is useless.a wedge is available follow instructions, but there aren't any. All of the decent videos are for lx200 and use the method I've tried, but it just doesn't work. I don't want to drift align, for now, I just want a simple enough alignment as meade expected,
  10. Ah yes, guiding, my next learning curve:) I already have a miniPC permanently connected to my scope, so I will be guiding, I get about 8-0 hours battery life out of the scope plus mini PC and all add ons so that shouldn't be an issue. I've got a Toucam Pro on it's way and I will guide using PHD2, which I think/hope will get me to 2-3 minutes OK. Yes I can get an image of mars, but at 12mm it is about the size of half a pea, not really worth doing, and then only for about 20 minutes before the tree eats it. If that tree died I would gain about 30 degrees of sky. I've got a 7
  11. That won't work on an LX, but I can piggy back.
  12. Ah damn, OK. So a 2" focal reducer of .63 or.5 would help. I'm also waiting for an adapter plate so I can use my wedge, that should get me to 2-3 minute exposures hopefully. At this time of year mars is behind a tree by 9:30 and I just find the moon so boring:) but I understand what you're saying so I know where I'm going wrong. So in reality I need longer exposures and brighter subjects. I do already have a 0.5 1.25" reducer, if I used eyepiece projection would that then work?
  13. Yes I am capturing in raw, I'll do that now and see if I get the same...... and yes on the 25 second exposure at 2% I get 9 stars. SO how did I capture so few, just bad luck pointing at a low density area?
  14. 1600 iso, maybe I was aimed at a low density area? Not a clue on focal length, my OTA is 2000, then I have the Mead APO 2" Diagonal and a Crayford Focuser then my EOS450D. I tried a Bahtinov before and had no success at all, maybe I should try again.
  15. Fixed this with a reset and patch reload. All working fine now.
