Weight capacity HEQ 5
      #6139924 - 10/15/13 10:21 PM

Hi all...Ok I have an HEQ5.Its rated for 30lbs capacity. My understanding is for astrophotography I should cut that in half.I have an Astro-tech 6 inch imaging newt. Its 11 lbs,plus the rings.1 pound for both rings.My Canon 550d and prime focuser is about 1 pound. The Orion awesome guider package that I want to buy is I think about 3 pounds for the 80mm tube/scope and another 2 to 3 pounds for the camera, rings and mounting bar.I would be pushing about 18 lbs.

My questions is would I be pushing the mount too hard? I also have to consider that I am in a colder environment in the spring and fall where I live.

Any advice would be appreciated.


Dave

I guess you should be fine with a good balance and no wind.

We had the Williams 110 on ours for a few years, no problem with it. But, if it was me, I wouldn't go with the 80mm guide scope package, been there, done that. We have the skywatcher ST80, which is the same telescope, different paint. It was a real PITA as a guide scope, because of the sloppy focusser.

We use the Kwiq now, qhy5 in a 9x50, works great with the HEQ5 and the EQ6. It's far lighter than the st80, and much easier to deal with.

We have upgraded the refractor, so, the TOA-130 has pre-empted the EQ6. The C8 will go onto the HEQ5 when we set it up, and I have no doubts that it will be handled just fine, C8 with the Kwiq guide setup.

Your 18lbs should be no problem for the mount. The 6" Newt is considerably smaller than my 8" which means less wind loading in a light breeze. I finally gave up imaging with my Sirius (HEQ5) mount when I discovered that my 8", guide scope, two cameras (imaging and guide) and cables brought the weight to over 30 lbs. Imaging was still possible at that weight, with good success getting exposures up to 5 minutes, my light polluted sky limit.

My old HEQ5 was rated at 35 pounds.

I used my 6 inch refractor and mount together many times. For visual it was great, but astrophotography required a good still night and for me to stay far away from the mount.
