Pluto in Sagittarius – Brisbane 3rd August

Hello,

I dusted off the C9.25 and as part of my re-familiarisation plan with good weather and little-used equipment, I thought I’d chase down Pluto. Presently, Pluto is located in the constellation of Sagittarius, shining at Magnitude: 14.06, some 31.64 AU from my back garden and some 32.49 AU from our Sun.

Here is an LRGB (5x5 mins L, 3x5 mins RGB) with the C9.25 and ST2000XM/CFW9 at the prime focus (F10, 2350mm). Pluto moved between the LRGB frames so it is a little smeared – how rude! The FOV is approx.. 17x13 arcmins at a pixel scale of 0.65 arcsec/pixel.

After a bit of a poor weather layoff, I was all fingers and thumbs but slowly, the imprinted memories of how to set up and use the equipment bubbled up into my conscious mind and soon the system was purring along. I wondered what celestial objects the lads and lassies at the Qld Astrofest would be observing or imaging as I sat under the light polluted skies of suburban Brisbane.

Cheers

Dennis
