Hi Josh,

yes that is one of my rigs, with one of my PME's (not the one you had; which I am still yet to turn on).

Further development in the last week or so. We are working on the passive cooling of the containers. A whirly bird has been installed with ground vents and the containers have been spray painted in surf mist. So far the improvement has been significant on the internal temperatures. Next step is to create an insulative box within the container which holds the batteries and power systems. That should then hold day temperatures to 26 degrees C all year round.

Hi Paul, that sounds pretty good. Is the insulated box within the container going to be touching the inside walls, or will it be a box (much smaller) with the container? Just thinking about any heat that the batteries give off, needing to escape and a too small a insulated box for the batteries, holding that heat in.
Looks great so far, its going to be a lovely facility.

Yes the insulation will be touching the side walls. Problem being that batteries rack is bolted to the floor and the batteries are very heavy to move at 70kgs each. It is a bit of an oversight but there are solutions to the problem.

Regarding the heat the batteries give off I will construct the box to be about half the size of the container, allowing room for expansion with another power station later when we build another shed.

It occurred to me that you could significantly increase the insulating value of the container if you spaced the insulation off the container wall by 50 to 100mm.

Final testing tonight of one of the dome imaging systems. That being the AG12 and QSI683 on PME mount. Seeing looks pretty reasonable overall. Guiding looks good too. Now just to collect lots of data. It's been a rather dry spell.

What about site security Paul, 10ft fence, barbed wire, robotic dog, CCTV, alarm, minefield, etc

Hi Trevor, some of this is already in play. We have CCTV and alarm systems in place. We have been reliably informed that we cannot place a minefield on the site, so I guess that is not going to happen . Not sure about the robotic dog either. I am pretty sure I don't have the capital for that outlay . A fence is on the agenda when we are approaching being online with customers. Although locals in the area have advised being inconspicuous. Large fences and signs apparently attract unwanted attention. For now it is pretty well secure with high security locks to all doors and the cameras informing of any intrusions to the site. None as yet fortunately.

Bit of an update:

We are still awaiting a development approval for our first shed at Swan Reach Imaging. The delay in approval has obviously set back the installation date. We are hopefully that we will have the shed installed and operational in February 2022 given how close to Christmas we are now.

In the interim though we are testing the site with imaging in our dome. So far the site is looking very good. In the last 80 days we have had around 77% totally clear nights and a further 6% of nights being partially clear. Given this data came from winter and spring weather that bodes well for imaging nights being offered at Swan Reach Imaging over the course of any year.

Transparency looks very good; we note that the sky looks very clear. Darkness is at 21.98-21.99 on moonless nights. Seeing is also looking very good too with FWHM values on data around 1.5"-1.8" on a regular basis. Some previous data at a another site within the International Dark Sky Reserve show that seeing can be as low as 1.3"-1.4".

I have attached an image of data taken from three sites (Clayton, Home and Swan Reach) but much of it is coming from Swan Reach Imaging. It is Ha data 780 minutes of calibrated and stacked data. Star sizes are native. Some minor processing has been done to show the core and outer regions better.

Exciting times for us and we are keen to get the entire facility and operational so that we can share those skies with clients.

Comin along Paul, a big undertaking for you, patience is a virtue here.
I can't wait to get to the point of finally imaging from Eagleview

They are some wonderful figures, the site looks real good, Paul.
