mount choice and guiding
      #4349255 - 01/29/11 07:39 PM

I'm ready to upgrade to an eq mount from my ed80/lx90 combo.
Would like to get some 5 minute exposures on a new mount.
If $1500 or so was my budget, would a sirius/atlas be better unguided or a CG-5/LXD-75 with a guider?

urr thats a tough one. why not consider a used atlas and an autoguider? i think you wouldnt exactly be happy with either of the two options you listed. while the cg-5/lxd combo is certainly capable with a small refractor putting a big SCT on it makes it a bit more difficult and leaves no room for growth.

Toss a hundred more into it and get an IQE45 - They've been reviewed here and found to be a rather good mount.

Hi Steve,
I thank a cgem and a guider would give you the 5 minut exposure you are looking for. new around $1700.00 or used
somewhere in the ballpark of $1400.00.

You're gonna need a guider with an Atlas unless you find an amazing instance of one. I'm not trying to be difficult but the chances of a 5min unguided exposure with an Atlas is low. Others may feel differently, but mine was not capable of that.

At 2000mm (same as an 8" SCT) there aren't many mounts that won't require guiding. My Tak NJP is a sweet mount, but I wouldn't shoot at 2000mm without guiding it.

actually i'd use the ed80 for imaging and maybe a 6 or 8" newt if I bought one.

Looks like the atlas might be in my future

A used Atlas and a inexpensive & light weight guider from KW Telescope. They make awesome little guiders, at a reasonable price. -David.

Guiding is not that easy sometimes.
