I remember when I first moved to Leonay, more than 20 years ago. There were market gardens, horses grazing in the fields, and the sky was dark enough. Now there's 3 new housing estates, the sky is bright orange, and you can read a newspaper in the garden at midnight. First galaxies and then narrowband became impossible. You've probably noticed your sky getting brighter by the hour, as it goes from rural to suburban. Here at the farm, the local towns of Orange (45 Km, 41,000 souls after the mining boom), and Dubbo (120 km, similar size) are distant patches of light on the horizon, but Sydney (310 km, 4.3 million) is still the brightest.
Thanks. I suspect a rural plot will also have to be much higher on our agenda if I am to see what this RC is truly capable of.

As good as you have rendered them, they are all low hanging fruit, thrice picked.
I suppose one of the problems I have is it takes me a while to "dial in" a new instrument...hence the images of well worn standard candles.

Frankly the RC isn't quite there yet.

I suspect there are small focal plane orthogonality errors (or collimation...hard to nail down) that I'd like to fully understand and account for...but are hard to quantify unless the seeing is reasonable. I've had tantalizing glimpses of imaging Nirvana: 5 micron stars across my 16803 sensor.

In my defence they also help me establish whether the instrumentation or my technique are capable of delivering A-list results or are simply an expensive folly....but rest assured, I'll move onto something a little more esoteric in due course
