Here at Goldfield Astronomical Observatory (GAO) we have a number of a different services that we offer. You can purchase high quality raw astronomical data or buy framed prints of our work to have delivered to your door.
Don't forget to check out our Gallery to see the quality of our data. We stand by our data and use it ourselves.
Unlike many other astronomy data services, here at Goldfield Astronomical Observatory (GAO) we are subscription free. You select the data you want, add it to your cart and upon purchasing you will receive an email with a download link to a largely unedited 16-bit RGB TIFF; we do a basic background neutralisation and colour calibration. We want to take some of the pain out of image processing by doing some of the boring and tedious work for you. To open up the world of astrophotography processing to a wider audience we do the pre-calibration of the data (darks and flat field), select the best of the data and stack it weighted for quality. At times gigabytes of data gets tossed during this process so that only the sharpest and best frames are included in the stacking process.

We are currently a very small operation with dreams of expanding as time goes on. As of writing this we have two telescopes, multiple cameras and only one high quality mount so only one setup gets to see the dark sky at a time.

As for writing this the only camera that we've been using with this spectacular 10" F/10 CDK is a ZWO ASI094 which is a full frame 36.3mp Sony CMOS, the same detector used in the renowned Nikon D810. With its high QE, low read noise and medium sized pixels it is the perfect detector for high resolution imaging. At an image scale of 0.4"/pixel it offers the potential for world class resolution, being able to detect fine structures within nebula and galaxies that many other setups are not able to. Pair that with the excellent seeing conditions at the site it can be one hell of a beast.

Unlike the Mewlon 250CRS, we use two cameras with the RH200. For the ultimate in wide field experience we use the ZWO ASI094. Being a One Shot Colour (OSC) when wanting to do narrowband imaging we use a QHY183MM with 36mm 3nm Astrodon filters. This is of particular importance when considering the Ha emission as 3nm is narrow enough to separate the Ha emission from NII. A 5nm Ha filter will pick up both emission bands, although this can be desirable as it increases SNR, it isn't a true representation of the Ha emission line.

Our Location:

We are currently located outside a small town on a 10 acre property in rural Victoria called Heathcote. This is where our name was born as the area is known as the Goldfields. The Goldfields within Victoria extends a long way north and to the west, an old mining area but with minor gold mining operations still taking place. Wireless internet speeds are slowly increasing which isn't a bother for us as the property is within driving distance of Melbourne.
The skies are dark, typically a SQM >21.2.
Seeing averages below 2" and it isn't unusual to get imaging runs less than 1.5".
