Quasar, PMN J1451-1512, Mag 19.14, Redshift (z): 4.76, Light Time: 13.0 Gyr. - Dennis - 2023-06-16
I used the Database Power Search in SkyTools 4 Imaging to generate a list of Quasars with a Redshift (z) greater than 4.5, and one of the targets returned was the QSO PMN J1451-1512 in Libra.
This is an image of that Quasar, PMN J1451-1512, Mag 19.14, Redshift (z): 4.76, Light Time: 13.0 Gyr (22 x 240 sec exposures) taken with my Tak Mewlon 210 F11.5 and QHY268M from my suburban skies in Brisbane (Bortle 6 to 7).
PMN J1451-1512
Quasar
R.A. 14h51m47.1s Dec.: -15°12'20" (2000) in Libra
Magnitude: 19.10 R
Redshift (z): 4.76
Light Time: 13.0 Gyr
Apparent Data for 2023 Jun 15 GMT+10:
Apparent RA: 14h53m05.4s, Apparent Dec: -15°18'10"
Takahashi Mewlon 210 F11.5
QHY 268 M Pro Bin 2x2
Thurs 15th June 2023 10:02pm to 11:41pm AEST
2023-06-15:T12:02 to 13:41 UT
22 x 240 sec exposures
I understand that the parameter 13Giga Years is a measurement of how long it has taken for the light from the distant Quasar to reach the Earth. I also understand that the current estimate for the age of the Universe is in the range of 13.7 to 13.80 billion years.
I have attached a professional observatory image (colour) from Aladin Lite (PanSTARRS), marking the location of the Quasar with a red cross.
Cheers

That is so cool! Thanks for sharing this.

Hi Dennis,
You captured that quasar very well. Nice job.

Thanks Greg and Phil, I took that approach that if Greg can list it and plot it, I figure I can take an image of it.
Cheers
