Two Quasars for the price of one!

Hello all.
Here is a pic of two Quasars in Grus: q2315 4230 mag = 20 is lower left. q2315 4227 mag = 18.3 is upper right. They are 9.7 and 8.7giga light years away respectively!
300 second exposure, unfiltered, SBIG STL11000M Self guided. 22" F4.5 Fork mounted Newtonian.

Pretty extreme imaging. Amazed how you can spot those things. How do you know where to find them in the first place?

fantastic - glad to see you are back up and running after the big winds! hows the observatory look now?

Hi Guys,

Marc, Sky Tools 3 Pro has stars and Quasars and pretty much everything else down to Mag 20 so it's a process of following the patterns!



Thanks, H0ughy. This was done al fresco - the dome is still a ways off regarding restoring to its former glory. I was mighty pleased with the performance of the camera and the scope though! The dome is off the driveway where it landed and back on the right side of the fence!

Hi Mike,

I have just recently received a filter set from Peter Ward but am a while away from getting the dome back after it blew off. Also the RA needs to be much finer in responsivity to the self guiding if I want to do seriously long stuff. As you can see 5 minutes starts to make the stars a a bit eggy even with self guiding.

Great to see some quasar images, congratulations on your capture! :) What are the redshifts for those?

[bkm2304]

Hi Rolf,

Red shifts are:
q2315 4230 z=2.83

q2315 4227 z=1.92

(Whatever z means when it comes to Quasars!);)

Thats impressive. We need more quasar images - there is nothing like those faint specks to fuel the imagination! :)

Ah, yes, Rolf! The joy of Specks!!!
