     The patches are avaible, look for April 2019 issue Gday All Just a heads up, the GPS Rollover patches for the LX200s and 497 "Autostars" are now up on the StarPatch ( many site thanks to Chris Carson ) https://stargps.ca/downloads.htm The patch works in the same way as all others, but the new "Rollover" option is not selected by default. If you need that specific fix, just select the default patch options as per usual, then select the GPS rollover option and any others you might "like" to have. I have tested best i can with both with my failing GPS lumps but have no ideas if there are any other oddballs out there , so all feed back on anything odd is welcome Have fun  Andrew Johansen Melbourne Australia

    No need to pay unless you feel obliged for their help.... The trial version is fine. Meade used several manufacturers for the GPS units, so different results. Michael

    The StarPatch team have a history of Autostar updates that fix Meade's firmware bugs, and this GPS Rollover is going to be a case in point, although to be fair it's not Meade's fault. Fixes for the AudioStar, the 497 Autostar (ETX and LX90) and Autostar II (LX200GPS) are working and will be released soon. https://www.stargps.ca/downloads.htm You don't need to bother with the software and instructions for installing their replacement StarGPS units, just StarPatch (SetupSP.exe) You'll find their loader is faster and much easier to use than the Meade ASU. You will need to install the free StarPatch loader utility. You can then use that to create and load the patch live ( best ) or you can use StarPatch to create a patched rom that can then be loaded using Meades ASU ( not best ) Note, the std patch does not have this fix auto selected. If you need the fix, just check the box I'll post when news of the releases become available . Meade seem to be totally at a loss ........... Michael

    The fix will be: All it will do is say If YY < 19 or YY > 50, add 1024weeks to the YY data Any working GPS's will return YY = 19 or greater for the next 19 years so the code fix will get bypassed and the actual returned date will get used.

    The Autostar II fix is imminent, then the 497 Autostar, then the AudioStar Michael

    The LX200 GPS guys are well on the way to releasing an Autostar II patch, then they'll move to the 497, then Audiostars. All it will do is say If YY < 19 or YY > 50, add 1024weeks to the YY data Any working GPS's will return YY = 19 or greater for the next 19 years so the code fix will get bypassed and the actual returned date will get used.

    For the moment, this from the guru's on the yahoo LX200 GPS forum, should include the 497 Autostar firmware used on the LX90: if you are "aligning" vs "unparking" just let it fix, manually change the date only and then align, It should work OK Meanwhile, we are working on a patch to cover it.

    Yes some Meade mounts too, they have used a number of GPS suppliers over the years, so not all pre-2012 mounts are affected. Michael

    PTFE is very low friction material but unfortunately "creeps" under load, in other words your washers will get thinner, and the ones with more load on because of the scope position will creep most. Again, microns here will translate to arcsecs in your imaging. So PTFE is fine for Dob bearings, no precision there ? but not between your wedge and tripod etc. Michael

    Have you installed the ASCOM driver ? Michael
  13. michael8554
    Too much data for my tiny brain to process, so what are your conclusions ? Guidescopes in adjustable rings with soft-tipped screws are often considered to be an instant source of flex - remember we're talking microns. Even with a basic ZWO ASI 120M guidecam I've never needed adjustable rings, there's always been suitable stars available. Michael

    Just what I used to do with the 600D ! Michael
  15. michael8554
    The banding problem due to AF sensors on the imaging sensor robbing light is getting worse with every generation of camera. There only used to be a handful of AF sensors, now there are maybe a hundred arranged in bands, I believe to improve focus when shooting HD video. Not usually noticeable on daytime shots, but dim astro images with high gamma stretches brings it out nicely ? Started to get noticeable with the 600D. Michael

    Observing - looking at objects through an eyepiece. Imaging - replacing the eyepiece with a camera and shooting images. The telescope becomes a big lens for the camera. Michael
  17. michael8554
    More into imaging rather than observing myself, but broadly speaking, F5 is good for observing galaxies and nebulae, which are large dim objects, an F10 Refractor or F12 Maksutov better for planets, which are bright tiny objects. GoTo mounts can be confusing to set up at first, but make it easier to find objects once you've mastered that. Michael

    Need more detail of what you want to do with it. Michael

    The mirror is the blue item in the cutaway. It should be securely locked at the factory onto the metal carrier that slides to give focus. The mirror locks bear onto tbe metal carrier, but if the mirror is loose on the carrier, it will flop. Not unheard of on Meade SCTs....... Michael
  20. michael8554
    Found an online cutaway diagram of the Edge HD, the mirror locks engaged the mirror. What are the conclusions of your comprehensive tests? Mirror locks only make a small but worthwhile difference? Much heavier RASA is flexing on the mount ? Michael
  21. michael8554
    Doesn't the "High-frequency Star Motion in GA tell you the seeing conditions ? Michael
  22. michael8554
    Well it would be interesting to see if there is any star movement during that small range. Michael
  23. michael8554
    i agree with Davey -T, my 8" Meade SCT doesn't have a mirror lock and flop has never been an imaging issue. But the RASA is a different beast, there are some corrector lenses inside the camera port, perhaps these are loose? Michael
  24. michael8554
    Well that must be disheartening for you. You can check if the mirror is locked or not: With the mirror locked, gently rotate the manual mirror focus knob while looking for star movement in short exposure download images. If you feel that the knob won't move obviously don't force it, that and lack of star movement would indicate the mirror is well locked. Michael

    What's your RA Periodic Error like ? Michael
