FAIL Observations, Tuesday 16 October 2012

Location: Home, outside back door
Conditions: Seeing good, clear but gathering cloud.
Equipment: Skywatcher 130, 25mm eyepiece.
Highlights: none

A mixed evening. Caught up earlier on writing up my logs from Oman so that’s a WIN.
However my observations with the scope as a FAIL. Didn’t find any of the targets I was looking for, although it was useful as starhopping practice. These notes are for completeness and for potential future comparison for when I do manage to observe these targets.
Clear skies outside with some cloud so I set up outside the back door. My plan was to have a crack at he September Sky at Night magazine Deep Sky Tour around Cygnus. Cygnus was to the west, close to the zenith just above the fir trees. That’s why I set up there. Tried for both the Pelican Nebula, IC5070, and North American Nebula with no joy. Below is the notes I put into SkySafari+ as I was working on them.

Pelican Nebula – IC 5070 Bright Nebula in Cygnus 16 Oct 2012 21:15
Did not find. From Sept S@N DST. Located the area between sars Cyg 56 and 57 by starhopping from Deneb. No sign of nebula though. Seeing is good tonight. Moved away and came back to confirm my hop and tried again to discern the thicker patch between 56 and 57. FAIL

North America Nebula – NGC 7000 Bright Nebula in Cygnus 16 Oct 2012 21:29
Another DNF from Sept S@N DST. I fancy i can make out some nebulosity but probably not. This is a big spread out nebula so using 25mm eyepiece. In the right area. Have referred to star charts several times to confirm. Too much grey and not enough black in sky. Tried to use Gulf of Mexico and Mexico areas as recognisable features and again FAIL

I’m about to give up on the Sky at Night Sept 2012 Deep Sky Tour. I just don’t think it’s possible in these skies.

Observations from the Back Garden – Friday 12 October 2012

Location: Garden, Home, Top of drive – had started down in middle of the so-called lawn.
Conditions: cloud gathering through evening.
Equipment: Skywatcher 130 scope, assorted eyepieces, new streetlight baffle.
Highlights: Andromeda Galaxy, M31

22:00 Andromeda Galaxy – Messier 31
First time out in the garden in a while. Was a clear night when heading home so I was hopeful to get some decent observing in. It’s also dark a lot earlier now. That’s how long it’s been since I’ve been out here. Not as dark or warm as Oman though.
I recognised constellation of Andromeda high to The East. I starhopped from Mirach through u and v to find M31, the Andromeda Galaxy which was distinct in the RACI view finder. Switching to the 25mm eyepiece on the scope Andromeda was very obvious. No detail but an expansive smudge of light from 2.5 light years away. I moved up to the 17mm plossl and it was OK-ish, a bit disappointing. I was starting to battle against gathering and drifting clouds though and the 6mm superwide was just useless. At this point I gave up. Cloud stops play.
It’s a start on the Sky At Night Magazine Oct 2012 Deep Sky Tour anyway. That’s Just as well as my November subscription arrived today. Also got the Moore Winter Marathon to try. I saw it on this month’s TV show. I never did get anywhere with the September Deep Sky Tour around Cygnus. It’s dark earlier though so maybe I’ll get a last chance early one evening in the next week.
I think I’ll set up a page to keep track of my observing objectives or plans. At the moment I feel like I’ve a lot of catching up to do.

I also pressed a new bit of kit into service tonight and it seems to have been a success. I mounted a large sheet of plywood on uprights that I can move around the garden to shield me from the street lights. It was very helpful in keeping the light out my eyes and stop it reducing my dark adaptation.
Only cost about £4 to make too.

Observations – Wednesday 5 September 2012

Location: Home, outside back door
Weather: clear at first, high thin cloud towards end. Getting colder
Highlights: Sadr, M29 Open Cluster, Epsilon Lyra Double Double, Andromeda Galaxy M31

21:21 Albireo – Beta Cygni Double Star in Cygnus
Started off here this evening to get the finders and scope aligned. It’s first item on September Deep Sky Tour from Sky At Night magazine.

21:48 Ring Nebula – Messier 57, Planetary Nebula in Lyra
I was set up outside the back door so there was some light from kitchen. Observed through 17mm. Tried 6mm eyepiece without any joy. My plan for the evening was to complete the August Sky at Night magazine Deep Sky Tour so I wasn’t hanging about much on things I’d seen before. I was going to have a quick whip round the things I had seen and bag the rest of them.
And onwards….

22:05 Messier 56 Globular Cluster in Lyra
Didn’t find it. There was too much stray light from the kitchen and it was disappearing into the trees anyway. I have observed this before though on 14 August.

My next target was M29

22:10 Sadr – Gamma Cygni Double Star in Cygnus
I used this as a starting point for a starhop to m29. Luminous yellow-white. Impressive number of stars in the starfield surrounding it. Although I can’t actually see the band of the Milky Way from my garden we’re in the main band of the Milky Way here.

22:27 Messier 29 Open Cluster in Cygnus
There’s something very appealing about this open cluster. Got here in a starhop from Sadr and through Cyg 40.

Using SkySafari+ on the iPad with the field of view rings marked really does help. I’ve got the hang of starhopping this way now. I should try it with a book of starmaps too though. There’s a lot of stars round here, a very rich starfield. M29 was east to spot in 17mm Plossl eyepiece. I went up to the 6mm ultra-wide. It was still easy to see despite it being very bright outside kitchen door. A was working at the kitchen table so the lights were on. I made a sketch, which I later tweaked and inverted in Photoshop.

One more from the August Sky at Night Deep Sky Tour and another new Messier object.

I had to chase the cat off too. She was catching mice under the table. I really didn’t need her taking them in. I’d have to go into the light to deal with that.

22:47 Double Double – Epsilon Lyrae Double Star in Lyra
I’ve seen this double before. The double is very clear in RACI finder scope. Splitting further to the components took some doing though. I did it with the 6mm ultra-wide eyepiece. I needed some help from the 2x Barlow but the view very misty with that. Not sure if it’s dirty. I cleaned it but there was quite a bit of colour aberration creeping in. I ought to get a lens cap for it. Having seen and understood how it splits with the Barlow in place I then went back to the 6mm on its own and now it was clear. The doubles split perpendicular to each other. The view is of course inverted when looking through the scope. The screenshot from SkySafari+ shows how they split.

So that’s the August Deep Sky Tour or Summer Triangle objects completed. I’m quite pleased with that. First one I’ve managed to see everything on.

23:00 NGC 6819 Open Cluster in Cygnus
Spurred on by my completion of the August Deep Sky Tour, I decided to make a start on the September one of objects in Cygnus. I made a start on NGC6819 but gave up pretty quickly. It was getting misty at zenith and with the Summer Triangle wheeling South West across the sky by this time of a night. I need to come back to it another evening and start earlier.

Decided instead to go for a bit of naked eye astronomy and learn a few more constellations that are starting to appear to the East.

23:30 Andromeda Galaxy – Messier 31 Spiral Galaxy in Andromeda
I finished off the evening with this, although not with the telescope but with the unmounted 9×50 RACI finderscope. Another new find and the second new Messier of the evening. Takes my total to 7/110.

I’d been wandering the garden learning and identifying new constellations. Cassiopeia was an easy spot and then I worked out Andromeda lounging above the roof of the house to the east side. I stood by the back fence with the RACI finderscope looking due east and worked my way up through Andromeda.

The smudge of M31 the Andromeda Galaxy was visible. It was too low and too East to try it with the scope though. The House was in the way.

It was getting cold and the high thin cloud was coming in so it was time to pack up. This was a really good evening though. (It’s taken me days to compile and write-up the notes.)
