Looks like my Lipo project so far may be working good, ran a trial last night with a 3200Mah 3 cell Lipo from my RC airplane.
I wanted to see how long that went for before using one of my larger 5000Mah batts, didn’t take much more than $5 for a 2.5mm connector with 6ft cable included and a Deans connector on other end for the battery. I have a small voltage meter we RC guys use to monitor battery levels per cell and combined voltage, meter just keeps displaying levels constantly then emits a buzz when it drops to pre programmed level. The loud buzz I muffled to a pitiful hum by dropping some hot glue over the little speaker holes, last thing I need is an 80 decibel buzz at 2am in my yard.
I set buzz for 3.5V per cell which is lowest you want to drain a Lipo per cell, after slewing around manually more times than I can remember I still had enough juice to slew around for another hour if i wanted, I was mimicking a nights slewing around and I think after I slewed around on both axis simultaneously on and off for 40 min I pretty much covered a nights worth.
the test will be in the field, if this battery doesn’t cut it I’m sure the 5000Mah will do the trick. I was watching for any shenanigans from the scope as the level dropped but nothing, no glitches or twitching of the controller display, all remained solid.
The next morning i turned on the scope (without recharging battery) and again spent the better part of an hour until i was just bored slewing the scope around, i was afraid to burn out a motor with constant back and forth slewing with a short pause of course.
i am now convinced that this 3200mah battery not much bigger than the average candy bar will last a whole night out and more! fantastic to know that when i drag the scope out for short periods locally (won't need heat strip those times) that this battery will be fine.
i was dreading having to take my 50Lb deep cycle marine battery every time id like to go for a short local 2hr outreach session, on those long drive dark sky all night sessions yes i will need heat and my marine battery but those a few compared to
short local sessions. I can now fit my power supply into my pocket and that is just GOLD!!
I often browse local classified ads for the odd person selling their scope for a great price, today I sort of hit the jackpot, i was browsing as usual and saw an 8” LX200 GPS that had just been posted (I’ll get to price later) so I call the fellow up who is an old timer saying he cannot lift it anymore and must let it go.
I make my way there, an hour drive, and there is this pristine LX200, the man was such a nice old fellow who enjoyed the scope for years. The optics look perfect, I gave it a shot at terrestrial viewing looking for the usual things like excessive mirror flop.
All seems great, computer and motors humming nicely, never been tampered with, plus it has a micro focusser and a hand controller which was a year old cause he stepped on the original in the dark of night.
It came with 3 eyepieces (Meade low end) regardless, I can’t believe it’s esthetic condition, it looks like it rolled off the line yesterday. Best of all, I handed over what he asked no questions, the equivalent of U.S. $450, now I think that’s a deal!!
After handing him the cash (not before) and thanking him profusely lol, I asked him why he was selling for less than what he could have asked, to which he replied, “look at my Home son, money is not my concern, I just want to see someone enjoy it like I did” sure enough I could place my entire home in one of his bedrooms haha.
Amazing person, there are still good people out there!

Thanks in advance
Hello! i am being offered this 100ED at a price which is hard to resist by an acquaintance who inherited it and doesn't plan on "checking out galaxies" as he put it LOL, it looks like a well built scope and a good frac is a scope for life, anyone have/had this scope?
