Getting a new scope/mount for DSO AP
      #6002528 - 08/02/13 02:14 AM

Hello all,
After some good feedback here I took advantage that I still had an open return window on my cube mount to do a return and plan to get a new, more steady set up for AP.

I've decided I would prefer to do DSO with some visual on the side.

I'm currently looking at getting the Orion Sirius EQ-G, but I also noticed that the Atlus EQ-G is at nearly the same price point, only $250 more.

Is there any major differences between these mounts for AP other then carry capacity?

Any others that perform the same or better at the same price point or cheaper?

Thanks!

setup and operation wise they are pretty much the same mount. Think of the Sirius as the little brother of the Atlas. the low point of the Sirius is the tripod, if it had the Atlas's tripod from what i understand it would be almost just as good as it. weight is the main and major differience between them and thus their capacity they can handle. the Sirius is a great visual mount for most any normal scope one would put on it, even 8" newts. for imaging you want to keep it lighter for sure but its just as capable as the atlas so long as its not overloaded.

Most people will recommend the Atlas-G over the Sirius. For imaging, a good mount makes a big difference.

When buying a mount the general recommendation is that you don't put more than 1/2 of the payload capacity on it (excluding counterweights). For example my AVX mount works very well with my AT72ED and AT6IN. However, if I wanted to use an 8 inch Newt, I would probably be best served with a CGEM or Atlas mount.

As far as 'other' mounts there is the IOptron iEQ-45.

One thing to be aware of is that the Atlas, which I have, is an absolute beast to move around. It is very heavy. If portability is a concern, you might want to take that into account. It is, however, an excellent mount at that price point. It was a big step up from the CG-5 I had been using.

As Jim states, the iEQ-45 gets a certain amount of good press as well. So does the the ZEQ25.

You don't state what will be riding on it and of course that might make a difference in terms of what we would recommend.

Some people find the Atlas class too bulky/heavy to transport easily, so that's something to consider if you need to always move the mount around (in and out of your home, transport to a dark site, etc.) For AP, get the most mount you can afford. If the extra $250 and weight aren't issues to you, I'd definitely go with the Atlas over the Sirius.

Edit: Madratter posted as I was writing. Great minds think alike

So far I am inclined to the Atlas as I want a platform good for upgrading in the future.

As for what to put on it, I'm probably going to spring for the Orion bundle that has an 8 inch newt and tag a coma corrector on it, then later on get an auto-guide set up.
Anyone know if that package newt can handle imaging?

Hi,

if portability is of little or no concern I'd opt for the biggest, most solid mount you can afford. (cost performance wise the Atlas is very hard to beat)

Kind regards,

Wouter.

Should be great with the Atlas. I have the AT8IN (very similar to the Orion imaging newt) and it is one of my favorite scopes for imaging. It will be critical to rotate the newt in the tube rings to achieve a good balance. You will need a good coma corrector with a fast newt. I started with the 1st generation Baader MPCC but I really like the new Baader Mark III I recently bought.
