Dual mounted my Apo's on my Atlas Pro cool.gif May try this out under the stars tonight

Be sure you let the SVA130 cool down long enough, you may be surprised at the eyepiece views when comparing them at high magnification until the SVA130 cools. Set them outside without any sunlight falling on them a few hours before sunset and the acclimation time will be shorter. My experience with medium size air spaced triplets is they need a good 30-120 minutes cooling time depending on the temperature difference between where they were stored and the observing time temperature. Also know that while you may not feel it any sun directly or indirectly hitting the tubes will warm them and the glass and cells. Keep them in the dark when placing scopes outside to speed waiting time for acclimation. Take notes and get back to us tomorrow!

I usually set the scope in my back porch storage closet a few hours before setup. It stays pretty close to outdoor temperature this time of year. By the time I get everything setup, it's right at thermal-EQ.

A little size comparison between the APM LZOS 130 f/6 and a Tak FS60CB:

Interesting fact: both of these setups give similar pixel scales and FOV despite the huge physical size difference.

Hmm, not possible without using the extender on the FS-60CB or a big reducer/flattener on the 130 f/6 using the same camera. Changing the camera also fixes the poor pitch/resolution of the 60mm optic.

Different camera indeed. Top one features the ASI183MM, bottom one features the Atik 16200. I'm running the 130 at f/4.5

Nice monster. Tame it.


The short USB cables would help a bit (one of my USB-C cables was actually too short) but the dew heater cables and the temperature sensor cables are too long for this setup, and I do not want to cut and reconfigure them, as with other scopes I need them longer.

Cheers,

Phil

Yep, a very recent release. I just noticed it a couple of months ago. There's a nice 61mm doublet also, with the same basic design. Both are available with an FR/FF.

Nice set up!!

 

Does your G11G have the G11 RA Extension Kit?  It looks like it does.

 

Thank you.

It does, and it's a very worthwhile accessory for a G11 in my opinion.  I got the mount cases, tripod case, Polemaster, rubber tripod feet, tripod mounting knobs, clutch knobs, and have altitude knobs and lower tripod levers on the way, but the Extension Kit is the best.  I also like the lower tripod levers, which replace the big round knobs.  With all three knobs attached, the tripod won't fit into it's case, but the levers should allow that.  

 

The tripod in its case, the mount in its cases, and my Starbound observing chair will stay in my car.  I only have to carry the OTA (in an Orion bag) and Pelican case of glass accessories back and forth to the car for observing sessions.  Now if only these skies would clear!

I can’t tell from the Losmandy website, but do you know if there is any protective foam or padding in the mount and tripod cases? I also have a G-11 with the RA extension, and have been looking for cases, at least for the head. From the website pics, there doesn’t appear to be much protection with those. Thanks.

There is a layer of closed cell foam at the top and bottom of the tripod case.  The mount cases don't have any padding, but they don't seem to need it because the two mount components attach firmly to the bottom of the cases (when you have the RA extension kit).  Once attached, they don't come into contact with anything but the bottom.
