Quote: An open plea to Meade's Lightswitch engineers. Last night I took my LS-8 out to a public outreach event in a parking lot in Richmond Hill, ON. The sky was beautifully clear and dark in all directions.I set up my LS-8 about 20 feet from the last row of cars and powered it up. It performed flawlessly until the North alignment step. The scope swung around to north, stopped, made the small motions to pinpoint magnetic north, then adjusted itself for true north. I stood behind it and watched it carefully aligns itself a good TEN DEGREES off Polaris, which I could easily see above me! After that, the 2-star alignment failed to find Sirius, then Rigel! I eventuially carried out a manual 2-star alignment with huge azimuth shifts required to center each one.Normally, the scope works beautifully, but this incorrect north fix is a major flaw in the process, and occurs at home and at public events. Please, I beg you, give us a new firmware revision with the ability to accept or adjust the find north determination! It's a few lines of code! It only needs to give me 20 seconds to decide before it proceeds automatically.I love this scope! This fix would, I'm quite sure, make these scopes far more reliable for suburban users, and result in far fewer RMAs from frustrated owners.I look forward to your response. Thanks in advance.

Quote:Hmm. I would never thought that Meade uses North alignment in this "full-auto" LS series. I believed that North alignment is an obsolete feature of first-generation GoTo systems. Personally, I had the same unpleasant experience with small ETX-80. After using Nexstar SE (which doesn't require pointing North or tube leveling) it was kinda new to me to use a compass,and check local magnetic deviation before observing session. And, after all these tricks, the scope veered away from proposed alignment star for at least 8 deg. And so on. I hate North align!Now it's pretty interesting to compare these two full-auto Goto's from Meade (LS) and Celestron (SkyProdigy). They may (or may not) have different logic of self-alignment. Clear skies, Serge
Quote:I personally think that Meade's determination of local magnetic North is highly accurate. It's that local sources of magnetic interference (including some steel elements on tripods, vehicles, etc.) perturb the local magnetic North direction. Walk around your property with a compass and see for yourself. I just want to be able to correct for that.Chris
Quote:No - the LS scopes use Autostar III and only have centre finder (calibrates the camera), and training the alt and az drives. No options for the other types of calibrations you mentioned above.
Quote:Many thanks - interesting idea (and all ideas welcomed!) I tried it - I tried fixing the time zone (it defaults to 'auto') but sadly no difference. Next I will reload the firmware completely (as soon as I can get hold of one of those obscure mini SD cards) and try that. Then sadly it's back to the shop...
