OK decided to get the Atlas EQ-G, whats needed?

still haven't pick an ota but leaning towards a newt.

If you're going to be setting up on hard surfaces like concrete, you might consider anti-vibration pads for the mount's feet to sit in. If you're going to power it with a battery, get a good one that will hold a charge well. Mounts are real funny about low voltage.
And if you decide on a big refractor like a C6R, I'd recommend the mount extension that Orion makes. That way, you're not sitting on the ground when viewing near Zenith.

Jumpstart battery of about 17ah capacity.
wondering about batteries. weight? how much stuff can be hooked up to a jump start battery before you need to move up to something bigger?
years ago use a deep cycle boat battery just be cause I had one in the shed. it was a pita to move around,lol
(hand trucks) to start with I'm sure I won't be running too much but down the road may add laptop and other things..
yeah still up in the air on ota! been without for 10+ years and remember the 10" lx200 was great. but a 10" newt seemed brighter as I remember,, my eyes aren't what they were so thats where my thought process is coming from. still looking at all of them, but the newt is kind of in the front running..

An SCT or a MAK would a lot easier to use.
yes a mak would be awesome. was tempted to jump on an orion 180mm last week but held off for now. which ever ota I get would be the only one for at least a year or more so wanted to go with a bucket to start with,,
here a question to help me decide. the last scope I had was an emc lx200 10" at the time I did get to look through some 8" and 10" newts and clearly remember the difference in brightness with the newts. so fast forward to now, with all the new coatings for the SCT's are they more comparible to the newts now?

You'll also need to power the mount. I think you'll want more than a 17AH jumpstart battery. My Atlas with a refactor and dew heater drain a 17-20AH battery in about 4 hours. Much better are Optima blue top deep cycle marine batteries. I have two, a 50AH and a 66AH. Either of those will power the same rig for many full nights without recharging.
You'll also want an adjustable observer's chair (or drummer's throne). And the 8" extension for the Atlas might come in handy, depending on how long the OTA you choose is.
I'd skip the VSPs if observing on dirt or grass. Keep 'em if on concrete, asphalt, wood or similar hard surface.
Depending on the OTA, you may also need a dew controller and a dew stip or two, and/or a dew shade. Dew controllers will require a splitter for your battery; one fork to the mount and the other to the dew controller.

I upgraded all four of the adjustment bolts to a stronger set with better grips. The original altitude bolts in particular proved to be little stress machines. Oh and of course consider EQMOD, it's a winner if you don't mind having a laptop along to view. I haven't used the hand controller for several months now.

Did anyone mention building an observatory for it?

Most newts are fairly fast scopes, while SCTs are slow -- generally f/10 unless you use some sort of reducer/corrector. I don't think visual brightness comparisons mean much.
Modern SCTs do have excellent coatings. If I were you I'd get an 11" Celestron SCT for that mount. I have a particular preference for Celestron, partly due to my location and also based on excellent service (and needing very little of it!)

Maybe I missed it but what are you planning to do with the telescope? Visual? Imaging? both? imaging at 2000mm or more FL can be quite challenging.
as subject says. will order the atlas EQ-G in the next week or so. what will be needed? anything? there's always something!!!

Regarding power, if used for imaging the mount should have its own power source, possibly regulated. Dew heater, computer etc... should be on a separate battery.

I always thought that was a great feature. I wonder if one can also autoguide sending pulse commands through the wireless connection. That would be cool.
I'm surprised the EQMOD folks didn't mention the virtues of using a wireless game pad with the Atlas. It totally ROCKS.
There would still be a cable going from the guide cam to the computer tho.

Having had an Atlas in the past I definitely agree. The tripod must be improved. I heard great things about the Losmandy but for maximum portability I use a Rob Miller. I think Rob can make one for the Atlas. It weights only 8lb. and it's incredibly solid. If I remember well it's rated for a load of 300lb.
I would address the weakest part of the Atlas - the tripod.

My suggestion would be to invest in a Celestron Edge HD 9.25 OTA. It seems to be the perfect size for the Atlas with the weight ratio perfect for AP down the road. C11's are heavy, so be sure you want to handle such a big scope if you decide to go that route and stay portable.

A "short tube" ie;f/4 8" SN works well on this mount<<I have<<
or perhaps one of the AT f/4 imaging units (since the SN's are a bit "scarce") Low f/l, wide fields, no mirror shift/slop.

Welcome to the Atlas Club. You will be very happy with this mount whether visual or photography.

I think that getting started in AP using a long FL telescope would be very challenging. My recommendation would be to start with a very wide field instrument, perhaps even a camera lens. A short FL would be far less demanding as far as perfect guiding/tracking not to mention the fact that fast f/ratio optics would require less exposure time. As we all know the learning curve is vey steep and it never ends.

Just my 2c.

so at GF's computer for now and missed a lot over the past few days. new computer will eat into OTA funds but the atlas will be order still, by this weekend!
