Been planning this one for a while - the enigmatic Einstein's Cross in Pegasus. Here's my shot from my London backyard from night before last via my Meade Classic 12" f/10 SCT+ SX Lodestar-Mx2 camera that clearly shows cross-like appearance unlike the field stars of similar magnitude.
The magic bullet is the camera software's sharpening routine aided, of course, by good image scale and resolution from my scopes native 3050mm fl boosted [inset] to 11.4m efl - imagine a scope 37ft long in a 2ft long SCT package ! Exposure was 105sec [=7x15s summed].
Visually, quotes CN DeepSky Forum, it needs a 20" - 28" scope under excellent seeing and very dark skies to glimpse the 'Cross' so I'm pleased with my result from suburbia.
Einstein's Cross is a gravitationally lensed quasar QSO2237+030 @ 8BLY immediately behind a faint foreground galaxy PGC 69457 [=ZW2237+ 030 - Huchra Lens] @ 400MLY - the quasar is split into four faint stellar images mag 17-18. Hope it's of interest
