Subject: First night's experience with ETX-105 Sent: Monday, June 21, 2004 10:06:49 From: James Eagle (firstname.lastname@example.org) I picked up my new ETX-105 from Scope City in San Francisco yesterday. At the store, I fired up the electronics (your suggestion ... thanks), did an alignment, and inspected for broken stuff. I was also checking for loud drive noise. All worked OK, but I discovered a broken plastic foot on the field tripod and a broken zipper on the tripod storage bag ... both of which were replaced by Scope City. (The manufacturing quality of the bag and the hard case I purchased were not great ... both are flimsy.) At home the setup and alignment went fine except I managed to hit the AZ stop several times before I realized what was going on. And I installed the 45-deg image inverter and managed to hit it on the base! Hopefully that won't happen again. And hopefully I didn't do any damage! Once aligned, I was rewarded with some great views of Jupiter, M4, Dumbbell Nebula, and Alberio. The seeing was not great, and Epsilon Lyra would not split with the standard 26mm eyepiece. Assuming the telescope survived it's first night with me, I'm looking forward to some great observing. Thanks for the great site! Jim
Subject: Re: ETX 105 Power Supply Sent: Saturday, June 5, 2004 13:14:49 From: Jim Beston (email@example.com) I managed to find a 12 V dc, 1.2A mains transformer which seems to work quite satisfactorily with my 105. One problem I hadwas thatit's power jack outlet was unfortunately, and in common with every othertransformer I have, a 2.1 mm x 5.5mm plug. The connection to the ETX is a 2.5 x 5.5 mm socket. It is of course quite easy to get adaptors via various sourcs on the internet, but like most people when I decide I want something,I want it yesterday! Since all of this week I've been lucky enough to be the only person in south-east England suffering from one of the most debilitating forms of influenza yet to visit the U.K., I have been unable till today to do anything about it. To-day I felt much better, soa hunt round the local "hardware" store revealed many power suppliesall of whichcome with every adaptor known to man. For some inexplicable reason however, the adaptorsare not sold seperately.After some searching (mostly in the wallet)Ipurchased a variable dcsupply (1.5 to 12 V dc at 1.5 amp) for 14. (~ $20). The supply for this device is the car cigarette lighter. How does this resolve the original problem which was to utilise mains power? Well, by the use of a couple of mini plugs (non-reversible to conserve the centre-pin +ve polarity) I candetach the cigarette lighterplug andreplace it within the 12V dc 1.2A outlet supply frommy mains transformer. Appart from saving me about 20 compared with the Meade products. I had the satisfaction of creating something useful and I can now use mains supply in the garden at home and the car's 12V dc supplywhen I take the ETX out. My wife is complaining that the lights in one of our display cabinets don't work any more (guess where I got the mini-plugs from) but I was going to replace these lightsanyway!! Kind regards Jim P.S. The 105 is working a treat since I backed of the worm-drive securing nut 1/8 turn as reccommended by Dr Clay.Planets etc in theeyepiece now stay there and no longer exhibit a frenzied form of St Vitus' dance!
Subject: FW: ETX-105/Electric Focuser Sent: Thursday, June 3, 2004 08:50:20 From: Brian Crane (firstname.lastname@example.org) I e_mailed the Meade people in the UK on this subject - no good. Has anyone in the US tried Meade on this - does anyone know if they intend to do something about an electric focuser for the 105 specifically, and to address the generic problems with the #1244 and #1247 that I keep reading about? I've had some great advice from some of your readers/contributors on how to modify a #1244 to fit, but I take the view that what I buy, especially at the price, ought to work straight out of the box, & I don't want to compromise my warranty. If we didn't have your site, I for one would have bought one, and there probably would be an awful lot of broken scopes out there, including mine!!

Subject: ETX 105 Power supply Sent: Wednesday, June 2, 2004 12:46:03 From: Jim Beston (firstname.lastname@example.org) Although I've been using Ni MH batteries quite successfully with my ETX105 they do , of course, run down at the most inopportune moments! I have a number of plug in transformers that I've accumulated for various devices and I was wondering if one of these might be O.K for my ETX. The one I have in mind has a 12 V dc 1Amp output with a +ve center pin. What do you think? Thanks JimMike here: 1.5A would work more reliably.
