Quote:Getting close to order time . . . VERY close!Orion is selling the Atlas GoTo for $1249. For how long I don't know. Wouldn't want to miss the sale.BUT . . . I still have a couple of concerns.1/ The CGEM can be polar aligned without access to Polaris.Can the Atlas?2/ I have a Losmondy type dovetail.

Quote: Aligning without access to Polaris would be very helpful to me as a pesky spruce tree has grown very large and denied me access from about the only site I have left.

Quote:i dont own one (yet) but im almost certain eqmod for the atlas can walk you through the same process the cgem does. that is if you're going to have a laptop with you.
Quote:Can you tie a rope to the top of the tree somehow so you can pull it aside to see Polaris?
Too much astronomy junk, the CFO is getting irritated.
Quote:Gee, with the Atlas at $1249 who's going to bother with the Sirius? It's still $1149.
Quote:...I was cheap and made my inclinometer with a plastic half circle protractor, piece of heavy thread and a fishing weight. Total investment was under a $1....
Quote:The biggest con of the CGEM is probably a spotty reliability history coupled with declining customer service quality.I should add that I wouldn't be happy with a C11 on either an Atlas or CGEM. The C9.25 is the biggest SCT I'd put on either mount, even for visual use.Jim
“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:I am new to this thread and just read it in the last hour or so, but it seems to me that some people are getting confused with the difference between Polar alignment and go-to alignment. The first of which you need to be able to see Polaris (unless you want to drift align) and is critically important for long period AP, the second of which is more for visual astronomy as your mount can correct for errors in polar alignment by tracking with movement in both RA and DEC.On the topic of these mounts, I to am looking into both of these and have found the discussion very interesting. Ultimately I am looking at selling my 10" Meade LX200R, which is a great visual scope and getting something a bit better for AP. My question would be, which scope would be better for AP, with no guiding, only good polar alignment and PEC. I wont be using my computer to drive, guide or control my DSLR (that is one of the beauties of them). I am leaning towards the Atlas..... unfortunately the price has gone back to $1399. Have to sell the Meade first. but at least my new AT65EDQ is on the way now for some wide field imaging before I delve into the next topic.... What OTA to piggyback it on.

Quote:Yes, it is the ASPA that I found attractive about CGEM over Atlas. Notice I used the past tense. The killjoys on this forum have ruined me! The CGEM has garnered such a bad rep for QC and reliability, as well as being only marginal in its ability to carry a C11 OTA and piggybacked appurtenances that I am licking my wounds and contemplating a more costly mount. Perhaps a G11 Gemini 2 or something even more costly.
