Quote:Yes, a difference between Oldest and furthers.The furthest galaxies that Hubble has imaged have been about 13 billion miles away, and because of this, they have been red-shifted well into the infra-red portion of the spectrum.To even have have a chance of seeing something this disant you will have to use a near infra-red filter.Hubble has four near Ifra-red filters for this purpose.But hubble also has image scale that you don't have. I doubt that your scope even with the correct infra-red filters would provide enough scale for these targets to even show as stellar points of light.Not that you can't find galaxies way out there. It might be possible. But I don't think you will come close to reaching the distances that Hubble does even with infrared filter. They just won't have the angular size to show up as anything more than a single pixel on your camera.Even in the hubble pictures, they often appear as only slightly bigger than stellar.Again, not saying that you should not try to see how far you can go, but the best you will do is most likely fall well short of Hubble.
Quote: Anyway, just look for a couple of glaxies a a few thousand light years away and hammer away at them. Virgo has a hundred or so.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy.
