Bought it used and when I went in to do some upgrades (JMI focuser and internal tube reinforcements) found the previous owner polished the primary with sandpaper. Parts have just been sitting around the garage and was about to clear it out for a new Newt. Let you have it for shipping costs.

    I visibly cringed when I read the title. I just had a similar accident using an AZ-GTI as a EQ mount. The skywatcher legs are twist clamps and one leg got loose in the cold on a sub zero night, and one leg clamp let go. It smashed a 2 month old full spectrum modified Sony A6000. It also damaged the focuser in a Skywatcher 72ed but I fortunately fixed it by taking it apart. Best of luck on your new telescope project.

    During Expo ‘86, I visited Vancouver and read archived copies of the Journal of the Royal Astronomical Society of Canada (RASC) at UBC’s library.
    There I read that in the sixties (IIRC), the Montreal Centre of the RASC observed from a 6th floor balcony of the Sun Life (insurance) bldg in downtown Montreal.
    One night their 6 inch refractor fell off the balcony.
    I returned home to Eastern Ontario. And I frequently observed with Terrence Dickinson in his driveway.
    Terry’s father had recently passed away and he was mourning his dad. A bit before midnight, we took a break inside his house and I told him the 6” refractor story from Montreal.
    Terry was beginning his use of Astro Physics refractors and had a 5” f/12 at the time.
    The destroyed Montreal refractor was just the bit of black humour that Terry needed right then. He laughed and laughed and laughed.
    The story seemed to relax him hugely. We had many superb observing sessions in his driveway.
    Ed, you’re an honourable man to pay up for your buddy’s scope.

      Terry D. had a Cerovolo 8.5” Mak-Newtonian for a while. Terry was a keen and accomplished planetary observer. The Mak-Newt had a very long cool down time and exhibited tube currents for hours after set-up.
      OTOH, it showed the cometary impact remnants on Jupiter very nicely. I was fortunate - to say the least - to observe Jupiter with Terry fairly soon after impacts. Fascinating!

Wasn't allowed to lift anything over 10 lbs for four weeks. Then bad weather settled over central Ohio for most of February.
    Finally clear weather this week but an earlier old foot/nerve damage reared its ugly head again. So bad it was waking me at night. My podiatrist administered some shots and put me in a walking boot.
    Well, I wasn't going to waste a clear night and walking boot and all I took my astro tech 115 out and got shots of Orion. Bringing it in, yes my boot caught a landscaping stone. I started stumbling forward my cement patio, tube and all. I don't know how, but I saved it.

    I dropped a Vixen SS 200 from a Vixen GP mount, because those saddles are funny, and designed specifically for that weird Vixen plate. Anyway, I was lucky. the tube had a significant dent by the primary, and it also landed on the focuser causing a deformation of the tube where the focuser is. I was able to make the area around the focuser near perfect, using some bent washers and screws, to pull the dents out. I learned a lot from that mistake.

    Many years ago (almost 20!) folks from Tucson and Phoenix were gathering at Farnsworth Ranch south of Arizona City for - I think - a Messier Marathon. One fellow from Tucson was one of the few that had set up the night before; but the rest of us started arriving mid-afternoon. He had a C11 on a very big mount (Losmandy?) with a solar blanket wrapped around it to keep the harsh AZ sun off of it. Well a dust devil came along, grabbed the solar blanket and tossed that setup to the ground. Corrector plate was toast - don't recall any details on the mirror. But man, there was a huge collective sphincter clinch when it happened. He just packed up everything and left.
    Many a mental note was made. Keep sails off the scopes.

    I have the reverse situation with a Losmandy plate adapted to a Vixen mount. The Losmandy plate slipped once and dinged one tooth of my focuser. It's still fully functional. I use a safety bolt on the dovetail plate now, so it can only slide up. There is not enough room on the Vixen plate to use a bolt, but at least the Vixen clamp has a main bolt and a safety bolt. The standard Vixen clamp is not popular, but it does seem less prone to slipping. I think they need to make some design adjustments.

  • @Martincohenphoto

    OMG Ed, I feel for you! Now, this scope was obviously made into quite a beautiful instrument by the previous owner. My guess is that there are still a bunch of these around with the original crappy plastic focuser, most likely out of collimation, sitting in a garage gathering dust. That's the one you want!! The owner will be thrilled to get $400 for this large piece of crap and that's where your renovation journey starts... Two ads, one on Cloudy Nights, one on Astromart, asking for a 10" Meade Schmidt Newtonian that is no longer seeing much use. Shipping will be expensive, but maybe they'll cut you a deal after seeing this video. Keep it up!! :)

    Don't feel too bad Mr Ting. I bought a Celestron Nester 8SE. On my second venture outside I didn't check to make sure the tube was properly seated in the mount. As the telescope slew it fell off the mount. Yes I now have a spider web on mine too. Called Celestron, they said since the tube had a small dent in the end it would be cheaper to buy a new one. They don't sell the 8SE tube only so I bought a whole new 8SE. The only positive out of this situation is I now have a Go To mount for my Explorer Scientific ED102 4" refractor. Now I can use both at the same time!

    Something just occurred to me - the stock dovetail bar is cast aluminum and is mostly a rectangle, not a dovetail (prism) shape - there is only a small area near the middle of the bar where the clamp can "bite". Your adapter may have been biting on a rectangle and not a dovetail. Check that - you may feel better afterward. (That system was cloned from Vixen, like so much of the LXD55/75 mount.)

    if you do experiment with the spherical mirror, do as I did and play around with different aperture masks to see if that much spherical aberration can be made tolerable.

I have really enjoyed watching your reviews and the astronomy community owes you a big thank you for your efforts. I have a 2000's Meade LXD-75 and the mount worked for about 6 months till it succumbed to a slipped gear. I still have the mount and thought about spending the money to have it fixed but I would probably be better off replacing it with something beefier like an Atlas. The 10" optical tube is still in great shape and would like to replace the focuser.

I, too, did have an accident--I managed to drop the secondary out of the corrector onto the primary when I was trying to do a collimation--result a slight chip on the edge of the secondary and a small scratch in the primary coating. What black Sharpies are good for! That secondary mount retaining ring is dangerous! Frankly, the way we mount our scopes on an EQ mount is pretty dicey--there must be a better way than pressure plates. I'm surprised we don't have more accidents.

    I've always felt that that design of dovetail plates, now they are pervasive in the hobby, lend themselves to the possibility of these kinds of accidents when a scope is near horizontal (due to the moment) or vertical (due to the lack of end plates).

Great scope for tic tac toeing up and down the Milky Way. It provided my best view of M31 ever using a 22 Pantopic. My ZWO cooled camera (294MC Pro) is very happy with the large fast aperture. On the downside aside from the focuser, the paint is coming off the tube in big chunks.

    I'm sorry that this happened to you Ed. I had my 8" F4 Orion oriented the same way when my mount decided to let go of that weird Vixen plate. Thankfully for me the real damage was a fairly small dent in the ota and a scraped up focuser knob. I don't know if this is a great solution, but you could always modify it with a conventional F4 mirror system. At least the tube and the focuser could still be put to use. For the old optics you could maybe modify it into a really good shaving mirror🙂

I would dig a hole and jump in if anything happened to that scope. Keep up the good reviews.

    Condolences on the loss of the instruments. But at least you didn't get hurt. I question the design of the Losmandy converter. Since it works by friction alone, I wouldn't even use it on the lighter scopes. It might be prudent to look for a better design.

    As for the SN10 - I sold mine to an imager because although the low power views were indeed fine, it struggled at 30x per inch. Like all Schmidt telescopes of the era, it was hit or miss if you'd get one that could take high powers. I built a 10" f/4.5 Newtonian to replace it. That has a Royce mirror and 1/20th wave secondary. BTW the "blue ghost" collimation method was my invention! :) It really did make a big improvement. All Schmidt telescopes need perfect placement of the corrector and secondary precisely centered in it. There is a lot of factory slop to reel in.

    The LXD 75 is fine. (Unlike the LXD 55 it replaced)
    Bought mine in 2004 (The SN8 version), still works great for me!
    I did a hypertune back in the day, but other than that, it’s pretty much how I bought it. YMMV

    I feel that. I have a classic 10" SCT and it fell off the tripod. Luckily it all hit the wall and cut into it before hitting the floor. The tube was attached to the fork arms still. It was very heavy. It fell into me, rolled over to the wall smashed into the wall and fell to the floor. I was on the bottom trying to get the screw in the center to go into the fork arms. Luckily nothing broke in the glass department, but I had a focuser on the back that was misaligned. I could fix it. Even the collumation was good. Now the blue paint is scratched though and there's a very slight dent on the outside.

    My LXD75 mount is now 20 years old and still runs perfectly. I would buy an f/4 paraboloidal mirror for it. Or take a class to refigure the mirror yourself. The hard work is already done, it's a sphere with a good edge.

    That's really bad luck, Ed, commiserations. Having broken a few expensive bits of kit myself I know how gut-wrenching it can be. It's not the cost so much as the "how can I have been so stupid?" feeling, and the sadness of ruining a nice telescope.

    So sorry that happened to Ed. I almost dropped an 8" Newtonian trying to put it on a too high mount. I waited until I got help, but your scope went on, but fell off. In hindsight you should've ..... I hope the owner gave you a break on the price.

    Hi Ed, sorry for your accident... Now considering the amount of damage, wouldn't it be interesting to try to .... glue it back together? Maybe with a ground marble reference plane that is accurate enough? But I have to admit that I don't know if you can find these at a reasonable price...

  • @paulcontursi5982

    Soon after I got my new 6 inch Mak, I accidentally tipped it over while I was adjusting the tripod legs. I was lucky in that the red dot finder absorbed all the impact. The finder was smashed to pieces but, luckily the OTA seemed to weather the ordeal unscathed.

    put an aperture stop at the center of curvature of the mirror and make a "Lensless Schmidt". The lensless Schmidt is probably the most planned but never executed camera in the hobby so it will be cool to get a test and review of one, make some good out of the accident.

  • @johnmeggers5059
    @johnmeggers5059 Před 6 měsíci

    I did EXACTLY the same thing with exactly the same scope, about 6 years ago or so. It's been sitting in storage since then. The funny thing is when I looked through the eyepiece after the accident, the image was COMPLETELY CLEAR. I as astounded. It happened about 6 years ago, and prompted me to move onto a different scope because I posted on Cloudy Nights and basically the response I got was "yeah, you might be able to find someone to make a replacement corrector plate, but it would probably cost 10x what the scope was worth. So I've moved on. But it's still an unfortunate accident. Mine also had an upgraded focuser (not a Moonlight, can't remember the brand off the top of my head) which I'd be happy to sell if someone is interested. The main mirror is also in fine condition.

    • @edting
      @edting  Před 6 měsíci +1

      Good outcome for you! I don't want to try looking through this one in this condition. The damage to the corrector plate is so extensive I'm surprised the secondary is still attached. It won't take much for it to break loose and hit the primary.

  • @JohnRitson78
    @JohnRitson78 Před 6 měsíci

    I had one of those and must have been lucky with my LXD75 10" version as the optical tube was pin sharp with great colour accuracy, as you said when fully collimated with a good laser as it took some time to master the art of collimation with it! The downside was the Meade's mount could not handle the weight of such an optical scope even when balanced perfectly the motors would struggle, and I had one motor replaced as well as a new handset.

    Sorry to see mate. I would not stay as composed as you talking about that Losmandy adaptor with its square base. What were they thinking?
    You could put a parabolic GSO mirror in there.
    The Celestron Astromaster 130 is notorious for some (many?) samples featuring a spherical mirror. I looked through one once. Low power views were ok but higher magnification - forget it. Not interesting, just crap.

    I made my own Vixen adapter for my mount using hardwood. I molded it to fit snug under the lip and then bolted onto the existing plate. Still, I cannot help but check it over closely before using each session.

  • @gammondog
    @gammondog Před 6 měsíci

    😬I wondered how one would make good to the owner but you answered my question. Send the owner a generous check with a letter of apology. I wonder if the machinery used to figure mirrors has advanced enough to bring down the price for parabolics to make corrector plates redundant. I bought my six inch mirror from Coultier in 1989. It was spect an 1/20th of a wavelength. Cost a pretty penny at the time.

  • @nerdinium
    @nerdinium Před 6 měsíci

    I've been thinking about laying down some of that thick rubber gym floormat around my telescope. It might prevent disaster for dropped eyepieces. Don't know if it would do much for a full 38 lb telescope.

  • @mitrovarr
    @mitrovarr Před 6 měsíci

    It seems like if someone wants to grind a mirror, you could grind the coating off the spherical mirror and then parabolize it. It would still take all the skill and a lot of the work of making a 10" mirror of that size, but at least there'd be a use for it, and you'd save the cost of the blank and some of the work rough-grinding out the curve in the beginning.
    If you could get the right lenses you could also try turning it into a Jones-Bird design (huge if, though).

  • @ultrametric9317
    @ultrametric9317 Před 6 měsíci

    One more comment - I helped a beginner set up a 5" f/5 Celestron she received as a door prize from her work. That had, to my absolute shock, a spherical mirror. Here is what you see. On one side of focus, you see a pattern of rings that looks like an archery target. On the other, it looks like just a fuzzy blob of light. There IS no actual focus. The ring pattern goes over into mush in such a way that NO focus is ever achieved. When you get to 4 or so rings, the mush takes over and you transition from mush to sharp rings without ever getting focus. Jupiter was just a pale yellow disk with no features other than hints of the equatorial bands. It was the worst telescope I've ever looked through. The limit for a spherical mirror depends on the aperture. For a 4" mirror, you can start to get good images at f/10 or so. For a 6", f/12 to f/15.

  • @Hubaround1

    This hurts to see. I’ve observed several times through the exact same OTA just still with the stock focuser.
    As for saving it… You can probably replace the primary along with a traditional secondary to avoid the wave errors or send to someone to refigure as a parabola.

    Hello, Mr. Ting;
    I'm so sorry to hear of your misfortune and the ongoing consequences.
    I appreciate your honesty and your responsible attitude.
    It sounds like your fellow club member may actually benefit from your misadventure.
    I don't think I want a Schmidt-Newtonian, after hearing your description.
    I have enough trouble w/ my cheap refractor & newtonian.
    At least I think I have enough mount/tripod for my OTAs.
    If I can I want an 8 or 10" Dob, just the basic 'eye full of sky'.
    I'm not adept enough to know if a scope is bad unless it is really obvious.
    I have no interest in astrophotography so I need much more than say, a XT8 or a XT10.
    Then again, I may try to sell my scopes & spend my nights in bed, if I could get to sleep.
    Thank you for sharing.
    Have a GREAT day, Neighbor!
