9AH will last all night, unless you are running a dew heater. In which case 19 AH will do for an all-nighter, or a couple of shorter nights. But if running a...
Thanks for the replies. Makes sense. I wonder if you could have another 19AH battery to run only a laptop? How long would that last? For future reference,...
This is a request for the sake of the group - so no one wastes time re- inventing the wheel or chasing a red herring.... Is anyone in the group sucessfully...
Yep, Although I had decided not to jump into this thread earlier on, that was going to be my recommendation. Do NOT rely on one single battery, get several of...
Assuming you start off with a fully charged laptop with a battery in good condition, say 3 hours use, particularly if you don't need to keep the screen on all...
I had a great viewing session last night with my LX-90 8" Classic. The scope did a great job finding many galaxies, etc., but the Autostar had a real problem...
Hi Mike, It sounds like you may have set the AutoStar 'Time' incorrectly. This may also have shown up when you did your initial Alignment, but you probably...
Meade has managed to set up a real bear-trap on their website. IF you use Meade's Autostar Updater (ASU) to "update" the firmware on your Autostar -and- choose...
Niall, thanks for your reply. I just turned my Autostar on, and the inputted YEAR was still 2008!!!! I feel silly and relieved at the same time. LOL!!...
Hi Mike, Glad to have been of assistance. 'Feeling silly' is always a good feeling - because it is MUCH better than 'feeling sad' ('cos you had managed to...
Okay, the whole Hydrogen based explosion thing places an uneasy feeling, not sure why. Plus, if having to buy better units in the future, why not go ahead and...
Great, but overkill. The hydrogen thing--The battery in the starter kits is the same as what is in UPS units, and many other things that need power over time....
Any reliable marine battery or good auto jump battery is completely safe and reliable. You are not drawing enough amps for any astronomical application to pose...
I agree with the 'smaller battery' approach. Bigger batteries can cause bigger problems if anything goes wrong. And they are MUCH more expensive. Stick with...
Yeah, well I love explosives, under controlled conditions, ie. high- powered model rockets and dynamite on July 4th. I guess it was just having that nervous...
I would say the 19mm Panoptic was an excellent choice Mike. I have a 20mm Nagler and it's my most used eyepiece. Regards, Ed Roach ... tried ... with...
The inverter situation can get more than somewhat silly however. Maplin (UK) are advertising a 3000 W, yes 3000, not 300, to be run off a car battery. At 12...
Hi all, Here is an image which was taken on August 22nd, but I never posted it. It is of the crater Walter and also shows Werner, Aliacensis and a portion...
If possible, avoid the inverter and run things directly off the 12V bus; your battery will run longer that way because an inverter uses some of the power ...
Ed, Wow, spectacular! I am surprised also at the variety of crater types visible there as well. Best Rob Crockett ... it. It is of the crater Walter and also...
The telescope and dew heaters do of course run perfectly happily from a 12 volt battery. And any laptop car adapter which produces 18+ volts from 12 volts...
Yes, if you fit Meade motors, either DS or LXD55. But not using the original HEQ5 motors - the Autostar interfaces to the Meade motors via a control card...
Hah! Talking about Maplin offers, here's a more powerful version of the one below, at the same price until 17th February. So if you've got a really BIG...
... One thing to -always- check out when using a DC-to-DC adapter for your laptop, if the laptop is -also- going to be connected to the telescope, is "which...
Thanks Rob! It is amazing seeing the variety of craters when observing the moon up close. Even when the Moon is washing out all the deep sky stuff, there's...
Thank you Luis! I'm hoping for good conditions soon to capture Saturn. The rings are edge on now, making it seem less impressive, but at least we can see the...
