Hmmmm, I wasn't sure how the ability to guide fit into the theme of "...I will mainly use this as my quick-ish look setup..." You can guide most (all?) of these mounts.

I had the same dilemma couple of months back and decided to go with lxd, reasons:
1. lxd allows to have reduced slew speed to avoid waking up neighbors.




Celestron added that capability with the GEM 4.19 HC firmware.

Also, the all-star polar alignment feature negates the need to have a direct line of sight to Polaris, if that's a factor for you.

I had both and both work fine. Neither is what I would call an AstroPhotography class mount. They will work, but are not really designed to do long term exposures. I mean they work and I did some shots, that I was proud off, but I had blurred stars in 25% + of my images and needed pretty good polar alingment to get that.

The differences are minor, the Meade was more accurate with 3 star alingment and more realiable to me.

The ASGT had a dedicated guide port, better hand controller but mine had to go back to Celestron for several months and gave me random errors.

I kept the LXD 75 as it worked day in, day out.

Whichever you pick will work fine.

i think theres some confusion. its the lxd75 that needs an st-4 adapter if you what to guide that way, but usually you use pulse guiding through the 497. the celestron can do both without any adapters needed.




Meade made an "Astrophoto Module" for a while for the LX90 that provided an ST-4 port for that telescope and some people tried to use it (with little success) with the 75, but it is long out of production, anyway.

yes the 909. it worked just fine, i used it. you can get a 909 clone now that plugs into the aux port and makes it into an st4, works perfectly as well.

Good to know! Does that mean any Celestron HC can be updated to this version?

No. The CG5 cannot make use of this feature. It requires an accompanying motor control firmware upgrade, and one has not been issued for the CG5. And may never be--I understand memory space was a problem.
