Description

I just wanted to know how far I can reach with my 8" reflector.
Is there a chance to detect any of the gravitationally lensed galaxies?

Especially  SDSS J1038+4849. It is rated at z=2.783.
Correct me if I'm wrong: z=2.783 equalises about 11.5 Gyr back in time. Or a about 2 Gyr old universe, isn't it?

I chose the 1.5x-barlow. Resulting in f6 - not sure if it was a smart decision - but I wanted a closer field of view because of the small size of  the object.

To be honest I didn't expect to catch up any of these very old photons. The estimated sky quality at my home base is rated at 20.84 mag...and seeing wasn't cooperative either.

In the end the light bucket did it, I suppose.

Gary and Albert you are the inspiration.
