Bootes: gx + QSO + globs + 'new' gx cluster

[nytecam]

After cursing awhile back of a fortnight of cloudy nights, the last 10 days have been wall to wall sunshine in 70F and clear nights. Again out last night this time in Bootes with Arcturus my goto star for scope alignment so thought I'd stick around. Here's a selection of images.

- data on each.

QSO1400+162 Megastar m16.4[v] but seemed a full mag fainter - no z values so distance unknown.

IC 983 - a complex gx [sloan DSS inset] with fainter/distant gx to south

.

NGC 5557 - a featureless elliptical gx - seem common to Bootes brighter gx.

NGC 5614 - a bright multiple gx with extended halo and feeble NGC 5615 hinted at.

Sloan DSS shows a v.faint 'vertical' gx cluster east

of N5614 that I've named Nyte#1 ! The gx are mag 17/18 from Sloan. Looks like an unlisted Hickson?

NGC 5466 - a sparse globular.

M3 [in CVn] is a splendid glob 5 deg west

of NGC5466 above.

NGC 5676 - @ 99 MLY - best gx of evening and not an elliptical gx !

A fruitful night - maybe more to follow..

Interesting cluster indeed near Arp 178. Strangely, LEDA only has PGC 2055993 (mag 18.7 at 2.4 billion LYs) at that location. You've also captured PGC 3560593, Mag 18.8 at 2.7 blys due south of the cluster. And the object that makes up the leftmost point of the near equilateral triangle to the left of your cluster is a mag 16.4 galaxy, much closer at 414 mly. If you're ever back in the area there looks to be a nice configuration surrounding NGC 5567 too, next door to Arp 69.

Keep 'em coming!

Thanks Martin - I knew you'd do the business on these v.faint gx and thanks very much for the data. I'll image near N5567 next time I'm out but the 'golden spring' breaks today with a weekend of cloud and rain so we shall see.;-)

BTW If that quasar (BL Lac object) is this one

_RAJ2000|_DEJ2000|Cl|nR|Name|n_RAJ2000|z|Sp|n_Vmag|Vmag|BV|UB|Mabs

210.6854|+15.9992|B| |MC 1400+162      |O| 0.245|BL  | |16.74| 0.46|-0.44|-23.1

in the Veron catalogue then the redshift is 0.245.

Thanks Martin - brilliant ! z = 0.245 = 2.92BLY - say 3BLY for BL Lac object;-)
