DSOs near Jupiter

[nytecam]

Short session tonight from late dusk to near-full moonrise after 8PM.   As Jupiter was my scope's "alignment star" I stayed in the area via Megastar for a couple of planetaries, a galaxy group, variable IR source R Leo etc  and a quasar @ 10BLY.   Jupiter+sats [1ms=1/1000s] and quasar [100s - negative for clarity] below for starters.   Data on images - used Meade 30cm f/4 SCT + SX Lodestar-Cx2 + SX s/w.

LEO continued...

N2954 = elipt gx @ ~280MLY

N3019 S no RV;  upper left pair gx both S type ~RV=+1500 z=0.005 = 70MLY
N3016 gx lower right can't be associated with above eg RV=+8869 =z0.0296= 400MLY eg x6 further away??
 

I've used from Megastar the RV/c = simple non-cosmo z to deduce object lookback-time/range in x MLY.

PK221+45.1 - tried for this PN but too faint to record.  In brief sub-exposures the central star is bright [see inset top left] and soft comet-like disk [via the scope focal reducer]
a sure sign of near-IR radiation that I've recorded before. The unfiltered Lodestar records to ~950nm in near-IR but skews the dominant IR to pale blue colour. Good find.  PN/central star = CW Leo Mira var carbon star C9,5 type.

PNG221.5+46.3 is a huge 12' diam inordinately faint PN filling fov but not recorded - the mag16 central star is and ID by Wikisky - PN shown inset from Wikisky.

R Leo is currently about mag 9.5 [visual AAVSO] but records many mags brighter due to near-IR captured by unfiltered Lodestar camera.

Data on images.

Interesting field indeed around NGC 3019. LEDA has NGC 3019 at 426 MLY, similar to NGC 3016, so you've caught two pairs at very different distances. Size here is no indicator of distance….
