Description

A few folks have asked for a picture of my rig/observatory setup recently.  

Here it is, a sorry tale of addition to the hobby I started out in only 18 months ago with a Canon 6D MkII and a Star Adventurer mount.  

This is my "wide field set-up".  A Canon 200mm USM lens mated (via the ZWO Canon camera adapter) to an ASI2400MC camera, piggybacked on a Skywatcher Esprit 100 with ZWO focuser, off-axis guider, 7 x 2 inch filter wheel and ASI6200MM camera.   My GSO RC8 sits on the shelf behind, patiently waiting its turn when the RC field flattener arrives.  

The mount is a Skywatcher EQ6-R Pro and pier was kindly made for me by my neighbour. 

Even with a total rig weight which is now at the 75% of the rated 20kg limit for the EQ6_R Pro, and a somewhat non-standard pier, I still get 0.2 - 0.3 arcsec rms tracking on a good night.   The whole rig is controlled by the ZWO ASIAir Pro and powered by a Hyundai 555Wh battery. This is enough to see me through a sub-zero 12hr night.  Although I have had precious few - if any - of those this winter.   My ASIAir is linked via an ethernet cable to my Google wifi unit, fixing the otherwise horrid connectivity of the ASIAir.  

The observatory roof has a eufy security camera on it, which I can use to monitor the rig from the warmth of my own home.  Great for those occasions when automatic median flips go bad.  

The observatory has a unusual steeply-pitched gable ended roof with cedar battens in order to match *exactly* the design of the rest of the house that the observatory sits alongside.  I had to design the length the observatory so the scope can still see the SCP (just to the left of the roof apex) and get down to within 20deg of the horizon - with exception of the South-West where trees limit me to 35deg.  That is OK since that is the direction of Queenstown/Frankton (pop 30000) about 10km away and getting increasingly bright.  I tend not to go there if I can help it.  Either astronomically or recreationally.  5km due North is Brow Peak (Alt 1600m),12 km due South is Double Cone of The Remarkables (Alt 2100m).  Great for dark skies, skiing/tramping.  Less great for seeing.  

Things to do include; cable management and a small welding job to brace the pier.  Also working on a sidereal clock using Arduino chip.
