Managed to get out the other night for a bit of imaging work. Still working unguided at the moment so I am keeping sub exposure times down to a maximum of 90 . seconds @ ISO 800.

Light Pollution will always be a problem but due to the location of the streetlight that sits opposite my rear garden then I guess I can only work with what I have.

First Image is a single 60 second exposure @ ISO 800 of Pleiades (M45), otherwise known as the 7 Sisters.

I was quite surprised at how much detail I managed to pull out of this image. For a single 60 second shot, I was amazed to see the start of some Nebulosity showing (Clouding) around the main stars.

M45 is an Open Cluster containing several hot B-type stars which are middle aged. Pleiades can be found in the constellation of Taurus. The cluster is dominated by hot blue and extremely luminous stars. The Nebulosity which was at first thought to be left over dust from the creation of the cluster is now believed to be unrelated. It is believed that the cluster is merely passing through an existing dust lane which is being illuminated by the stars.

Pleaides has a viusal magnitude of 1.4 which is bright in astronomical terms.

The next subject I chose was that of M42 (The Orion Nebula). This is a favourite with most imagers for several reasons.....a/ it's very easy to find being the middle star in Orions sword b/ it is visible with the naked eye or small binos and because of its size also usually gives a pleasing image.

Its not the best image and needs more subs to a/ bring out more detail b/ reduce the noise. That said, I am still pleased with the image given my limited experience. I will certainly be revisiting this over the next couple of months.

The next image is a bit different from the norm. I chose to have a look at a Double Star called Albireo.

Albireo which can be found in the constellation Cygnus looks by the naked eye to be a single star but is actually a Double Star consisting of a brighter yellow star and a fainter blue star. 

Finally, I had a quick go at M81 (Bode's Galaxy) which is a spiral galaxy about 12 million light-years away in the constellation of Ursa Major. i was surprised to get anything out of this image with using such short exposures. You can just make out some structure to the spiral although the core of this galaxy is clearly visible.

Longer exposures, far more subs and some callibration subs will really bring this image to life. Definately one to keep working on.

My next mission, weather permitting is to sort out this guiding. I have all the kit but need time and weather to get it all up and running. Once setup, this will vastly help my images.

PSP2012 (Peak Star Party)

I went to my first Star Party last week....The Peak Star Party 2012 which was hosted by members from SGL (Stargazers Lounge), an online Astronomy Forum. The event was held at Shallow Grange Farm where we were all made very welcome. Facilities were good and the place was full of like minded people all interested in astronomy. There was easily 200 people at the event either in tents, Caravans or Motohomes.

The Sky at Night Team (Paul Abel, Pete Lawrence & Dr Chris North) were also in attendance closely followed by a BBC camera crew. The show will be aired in Jan 2013.

Although the weather wasn't great, I did manage to get a few hours of observing over the weekend. Clouds on Saturday and thick fog on Sunday morning made life difficult but we are an hardy bunch so standing in freezing fog at 3am waiting for a break in the clouds is not unheard of.

I got to have a play with a 16" Dobsonian which gave me amazing views of several of the sky's hidden gems.

The actual stargazing may have been in short supply but from a social standpoint, this was a great weekend. I met some great people and had a few good laughs as well as a beer or three. Even my partner and my little dog enjoyed themselves.

I would absolutely recommend to anyone who has an interest in astronomy to pop along to a star party. People are very friendly and will gladly let you look through their scopes. A great way for a beginner to test equipment and also pick up great advice.

Second image from last night is of M27 (The Dumbell Nebula).

This was a real pain to edit with limited editing skills but considering it was an unguided 90 sec stack at ISO800 under badly Light Polluted skies, I'm still pleased to have managed to image it.

The Dumbell Nebula (also known as M27 or NGC 6853)  is another of the Planetary Nebulas. It was discovered by Charles Messier in 1764.

Planetary Nebula are generally faint objects and are a relatively short lived phenomenon, lasting a few tens of thousands of years.

The name "Planetary" originated with the first discovery in the 18th century because of the similarity in appearance to giant planets when viewed through small optical telescopes.

 SO, you ask?

Why are these objects called "M" or "Messier"?

Charles Messier (26 June 1730 – 12 April 1817) was a French astronomer most notable for publishing an astronomical catalogue consisting of deep sky objects such as nebulae and star clusters that came to be known as the 110 "Messier Objects". The purpose of the catalogue was to help astronomical observers, in particular comet hunters such as himself, distinguish between permanent and transient visually diffuse objects in the sky.

Managed to get out for an imaging session last night after work. The skies were clear so it was an opportunity not to be missed. I chose to have a look at M92 which is called a Globular Cluster. Discovered in 1777 by Johan Elert Bode, M92 is about 26,000 light years away from earth and can be found in the constellation of Hercules.

Globular Clusters are very tightly bound clusters of stars bound by gravity which gives them their spherical shapes and relatively high stellar densities towards the centre.

The setup, Polar aligment and 3 star alignment went well giving me a better and longer exposure time (unguided) of 60 seconds per sub @ ISO800 without any noticeable star trailing.

The set of subs (20 light and 10 darks) were then stacked in DSS (Deep Sky Stacker)to produce a single image which was then processed in Photoshop in order to produce a final image.

This is a single 60 second exposure before stacking or editing:


This is the finished image after stacking and editing

First Mini Movie

Got up nice and early this morning and thought I'd take a few shots of the Moon using my SPC900 webcam attached to the ED100 Pro refractor.

I can use the created 1200 frame Avi file to make a single stacked image or I can keep the video footage to create small movie files.

This also gave me the opporunity to have a play with Microsoft Movie Maker.

here is my first quick video.

Being new to this hobby, a lot of what I am doing is nothing more than experimentation and hopefuly learning what I can and can't do with the various software choices available to me. a real case of trial and error.

First Deep Sky Object

Got setup tonight for the first time with my new scope and managed to bag my first Deep Sky Object.

The Ring Nebula.

It is located in the Northern Constellation of Lyra and also catalogued  as Messier 57 (M57), or NGC 6720. It is one of the most prominent examples of the DSOs called a Planetary Nebula. It was discovered by Antoine Darquier de Pellepoix in Jan, 1779. It has an apparent Magnitude of 8.8.

This invisible to the naked eye Nebula is 2,300 Light Years away, So.................Pretty far away.

I took 12 Images (lights) and 3 Darks (these subtract the noise from the lights) in order to get these images. Each Light was a 30 second exposure @ ISO 800.

I would have liked to do longer exposures but my alignment was slightly out so anything longer was giving me elongated (eggy) stars.

First image is a wider shot with M57 in the middle:

Things to learn from this first image is that Astro-Photography is a very steep learning curve but one that is filled with possibilities. I hope you enjoy following me on this journey.

These are some of my early images of some of our nearest neighbours, taken using an SPC900 webcam connected to my Skywatcher 150PL. Seeing wasn't always great so they are not the best images but considering some of the distances involved, not bad for a beginner. I hope to vastly improve on these with my new setup.

Firstly, if you are reading this......WELCOME!!!

I am a relative newbie to Astronomy and a total newbie to blogging.

The aim of this blog is to record my journey into my new hobby.

I have always looked up to the stars with interest and had a cheap Tasco refractor telescope bought for me many years ago. Although it was poor quality, it did afford me half decent views of the Moon and planets.

This year, 2012, I purchased my first proper telescope, a Skywatcher 150PL on an EQ3 mount. This was partly purchased due to a genuine interest and also partly due to the Professor Brian Cox effect after watching BBC's Stargazing Live.

The Skywatcher 150PL:

This is a great visual observing scope but is limited for imaging due to the mount i.e. SW EQ3/2. Whilst the mount is more than adequate for a small basic scope it struggles with bigger scopes. 

The 150PL is great for observing Lunar and Planetary being a 6" Newtonian telescope with a focal length of 1200mm.

I modified the end cap with Baader Solar Film in order that I can use it as a Solar scope.

WARNING: Never look directly at the Sun through a telescope unless you have a correctly fitted, serviceable solar filter. Improper and unsafe use can cause instant Blindness

I fitted the mount with an RA Motordrive to help track my chosen subjects better and used an SPC900 webcam for basic Lunar, Planetary imaging.

Although this Scope has served my well, even taking into account the poor British weather, I really wanted to get into proper imaging of DSO's (Deep Sky Objects). 

My latest purchase is a full imaging rig which includes a Skywatcher HEQ5 pro Goto mount, SW ED100 DS Pro refractor Telescope, SW ST80 Guidescope and a  Canon 50D (already had the camera).

New Toy (complete with Dog)

This setup is going to be added to utilising some PC Software called EQmod which will allow me to directly connect the scope to my laptop so that i can control it via Some free Planetarium Software called Stellarium.

Once setup, I should be able to set up outside then control and see the stars via the comfort of my armchair.

The aim of this Blog will be to allow you to join me on what will no doubt be a huge learning curve and also to hopefully show you some of my images of the Universe and all its wonders. It will also be used as a personal record so that I can see how I progress with experience.
