Description

I thought I'd try imaging a truly distant object, so tonight I used SkyTools4's "Bright Distant Quasars" object list, and found that the Quasar FIRST J07472+2739 (R.A. 07h47m11.2s Dec.: +27°39'03 (2000)), in Gemini about 30 arcmins away from Pollux, was in an ok although not very high sky location tonight from my rural backyard. This quasar's light takes about 12 Billion years to reach us according to SkyTools4's notes on it. It is quite bright for such a hugely distant object at Mag 17.2, and my Beamtech CDK250, 250mm (10 inch) aperture Corrected Dall Kirkham telescope has managed to image it and its red shifted colour (Red Shift of 4.11) quite clearly, with a stack of 9x5 min exposures (45 mins total time) using a ZWO ASI2600MC Pro camera with no filter. The scope is mounted on my 10Micron GM1000 Eq mount, and the image capture was done with a ZWO Asiair Plus device. I stacked the 9 exposures with Astro Pixel Processor then cropped, processed and annotated the stack in Pixinsight and Adobe Photoshop Elements. Captured from our rural location in New Zealand. Next challenge might be to see if my little ZWO Seestar 50mm aperture Smart Scope can also resolve this same object. Some people have been imaging objects down to Mag 19 with those, so it might work with a long enough stack, but maybe not. I have a darkish Bortle 2/3 sky.
