After having a weekend away and missing the JOG observing sessions an observing session was organised for the Maramarua Forest. The cloud in Auckland was worrisome, but it was clear beyond the Bombay Hills.

I was first to arrive and setup and was away observing by 7:20 PM. Dave and Guy arrived at about 7:45 and setup the Binos. The skies were good but we were in for a cold one. Ice had already formed on the trailer by 8:30 as others started to arrive.

I planned to chase some Herschel II galaxies in the Libra and Serpens direction.

 

ObjectTypeMagnificationNotes
NGC 6118Galaxy88xSmall diffuse galaxy, oval in shape, near a bright 6th Mag star.
NGC 6070Galaxy88xSmall round galaxy with a hazy halo. No detail and even in brightness and near a bright 6th Mag star. Herschel II Object.
NGC 6106Galaxy88xHard galaxy to spot. Adverted vision a must. No detail noted but probably oval. Hershel II Object.
NGC 5970Galaxy88xA slightly more oval than round galaxy. Fairly bright and easy. Just south of a bright 7th Mag star. Herschel II Object.
NGC 5812Galaxy114xSmall round galaxy, quite like a small globular. Located on the end of a 'D' asterism. Defined and bright with a condensed core. Herschel II Object.
NGC 5885Galaxy114xFaint galaxy with no real special details. Object nearby a target object. Hard to spot.
NGC 5872Galaxy114xSmall but very faint galaxy near the NGC 5861 pair. Featureless and adverted vision necessary.
NGC 5861Galaxy114xGalaxy pairing NGC 5858 & NGC5861. NGC5861 is oval and even in brightness, brighter and larger than the nearby NGC 5858. NGC5858 has a stellar core, but no other features.
NGC 5858Galaxy114xGalaxy pairing NGC 5858 & NGC5861. NGC5861 is oval and even in brightness, brighter and larger than the nearby NGC 5858. NGC5858 has a stellar core, but no other features.
NGC 5878Galaxy114xFaint galaxy with a hint of irregularity. Condensed core, probably a spiral. Herschel II Object.
NGC 5728Galaxy114xAn oval spindle shaped galaxy. No halo noted but has a condensed core. Hershel II Object.
NGC 5597Galaxy114xA pair of evenly bright pair. Same shape and size. Twins. No detail noted in either. Both are Herschel II Objects.
NGC 5595Galaxy114xA pair of evenly bright pair. Same shape and size. Twins. No detail noted in either. Both are Herschel II Objects.
NGC 6729Bright Nebula114xWispy Nebulosity lit by R Coronae Australis with the nearby NGC 6726 also making a spooky nebulous area. No filters used. Nebulosity is distinct without the help of the filters.
NGC 6726Bright Nebula114xGasous nebula around B957. Extensive nebulosity is the nearby NGC 6729.
NGC 6723Globular Cluster114xA fantastic bright globular cluster, easy in the finder, with nebulosity on the fields edge. A fairly loose globular cluster by standards really.
NGC 6325Globular Cluster114xSmall compact globular cluster, faint but distinct from the starry field.
NGC 6287Globular Cluster114xA small compact globular cluster, faint but distinct from the starry field. Near a strip of dark nebulosity.
NGC 6235Globular Cluster114xSmall compact globular cluster, fairly bright. Not resolved.
IC 4634Planetary Nebula114xBrightish planetary but almost stellar. It is not stellar though. Adverted vision 'grows' this object making the disk look larger.

 

 

 

Last observing session I had bit of difficulty getting the mirror section onto the cradle section. I had done some work on this and I believe I have solved this problem. Snapped a Paracorr screw tonight which meant that I was limited to the two 2 Inch Naglers.

Most of the objects tonight were faint with not much detail but the finder proved it worth yet again.

Cheers.
