Went for these 2 planetaries in one image, a big 90 minutes total exposure time 9 x 10 mins ISO 800. The 2nd one, Du Re1 is VERY faint, in fact its magnutude isnt given, and its barely visible even in the UKST Ha survey. Wray 16-121 is blazingly bright in comparison lol. It has a wierd shape.
2nd image is 2 more obscure and much smaller planetaries. Shorter exposure is He2-84 and he2-85, 3 x 10 mins ISO 800. He2-84 is readinly seen , He2-85 is small and faint, Im 90% sure Ive identified He2-85.
Both these groups of planetaries lie near the bottom of the southern cross, a few degrees apart. Both images taken with UHC-S and uv/ir filters, MPCC, 10 inch F5.6 newtonian, Hutech modified 350D.
Note, the jetstream was in full swing, seeing was horrible, the guidestars were jumping around, and small sharp stars were impossible to get in images.
