Great end to 2013

Leading up to Christmas 2013, Cheryl hinted and hinted at the idea of getting me a watch. I've been without a watch for a while, and she's even asked if I wanted to go in shops looking for one. I even asked her if her present to me was something I'd not had for a while and she laughed. Come Christmas morning, she gives me a small wrapped gift. I tear back the paper and it's a tin, the kind of tin a watch would come in.

I read the top of the tin lid to see it's a QHY5L-ii guide camera / CCD camera. Chuffed to pieces would be an understatement of how happy I was. I jokingly put this on my Christmas list as it's a fair piece of money, so couldn't believe she'd actually bought it.

Jump to a few days later, I've sussed out the way it fixes to my finderscope and installed the required software on my laptop. Part of me was hoping for plenty of clouds as it's always a little daunting getting a new piece of equipment in the hobby of astrophotoraphy - nothing is ever simple or straightforward.

Surprisingly, after maybe an hour of playing around and clicking different buttons, I managed to get the guide camera fixed on a star (for those of you that don't know, a guide camera "watches" a selected star and tells the mount to follow it exactly, you could say the guide cam acts as an eye for the mount).

My first image captured using the guidecam was the Triangulum Galaxy (Messier 33). This shot below was a total of 29 minutes exposure, with each image at an exposure of 160 seconds. Before the guidecam I was unable to image longer than 70 - 80 seconds without the stars trailing off. Safe to say this camera is doing its job!

Which brings me on to my final image of 2013...

The Horsehead nebula has always been my favourite nebula in the night sky - having never seen it, I've always awed over images online and in books. The mysterious dark cloud in front of the nebula, forming the shape of a horses head looking away from you into the dark distance of the universe.

New Years eve 2013 I headed out with all my equipment and set up, with only one target in mind. Cheryl was busy inside baking cookies, neither of us really caring much for the hyped up day of the week.

After almost two hours inside, I came in with the captured images and spent around an hour editing the curves and levels of the final stacked result. This image is around 20 minutes of exposure (I had a few problems along the way which caused a few shots to fail sadly) and is most likely my favorite shot so far. I can't wait to get out and try again when the weather clears.

Andromeda Galaxies

Andromeda is the closest galaxy to our own, and is getting closer. Eventually the two galaxies will collide and become one great galaxy (we're talking billions of years however). It's a good target for any astronomer, and on a clear night is visible with the naked eye. Currently it isn't in an ideal part of the sky for viewing, as it is quite low down and close to the horizon - it only starts to become clearer at around 01:00am.

The first sighting of Andromeda with the 300mm lens on the CG-5 mount came out pretty well. The following shots were taken from a few separate exposures and a few dark frames put together in Deep Sky Stacker.

I'm really happy with the fact I caught two other galaxies within it (click the image to see labels) as I didn't expect to be able to pick them up. I know the final image isn't great - but it's definitely something to work and build upon.

M13 Cluster in Hercules

M13 is a globular cluster within the Hercules constellation, formed of about 300,000 stars. This was one of my first target with my new tracking mount, as it's a little fainter than other targets but still visible with a pair of binoculars.

Having set the mount to find the cluster, I took a few shots and was a little confused - I couldn't see anything resembling a cluster and as it was one of the first uses of my new mount - being a total novice I was sure something wasn't right. So I popped indoors to check on Stellarium where the cluster sits within the Hercules constellation - a quick diagram drawn on a post-it note helped me pin point it. It turns out I had captured it, but it was a lot smaller and fainter than I initially thought. The first shot below shows the image I initially captured, if you click on the image you will see where on the image the cluster is.

This weekend just gone, I stayed at my parents who live on the coast and have much darker skies. I stayed out for a few hours before tiredness got the better of me. I had three targets in mind, one of them being M13 again. 

This time I took 16 minutes worth of exposures, with 8 minutes of 'dark frames' which are used to subtract any noise on the sensor itself. I was pleasantly surprised with the outcome, after a few hours trying to get a decent results from the shots I took - the clear build up of stars as it gets toward the centre is pretty fascinating.

Report: Hunting the Milky Way

Having never actually captured the Milky Way (that big ol' galaxy of ours) I went on an adventure last week and took advantage of a relatively clear evening. I drove over to the Isle of Sheppey, in order to find as darker skies as I could within a reasonable distance. A 25 minute drive saw me in the middle of a number of fields, surrounded by a country path, some noisy birds and, well, that was about it. See the red dot on the map!

I'm going to travel to a few places around my area to find dark skies, and to find appropriate places I could set up my new tracking mount, without getting too much unwanted attention.

I took my camera and tripod out, and once parked up positioned the tripod just outside my car window -using a wired remote I was able to snap shots of the night sky without leaving my seat.

As it got darker, and my eyes adjusted, the milky way became more and more visible to the naked eye as a misty streak of stars drifting from one horizon to the other. I took a few hundred photos, but only happy with a few - it seems the milky way is a pretty tough target regardless of its size. Balancing the exposure to capture the feint stars, without filling the shot with light pollution was also a challenge.

The below shot was my favourite from the night, with the Milky Way clearly visible rising up above the horizon. The majority of the light pollution came from over the water in Whitstable. I may in future try move further West to reduce the light pollution, but like with many aspects of astrophotography - trial and error seems to be the way forward.

An adventure into space

My first lunar capture (September 2008)
1/200, f3.5, ISO 64, 303mm

I'm not quite sure how to begin, it feels as though I should be all excited and enthusiastic about this new journey into the realms of astrophotography.

But in truth, I've been doing astrophotography longer than I have been into photography. The photo on the right was taken on the 13th September 2008. Back before I knew what DSLR's were, before I was regularly uploading photos to Flickr, and before I had any idea how seriously I'd get into the hobby. I had a Fujifilm Finepix S5700, a simple inexpensive point-and-shoot which had a 10x optical zoom. Having figured out what manual was, I captured this shot at 10x zoom on a tripod outside my window. I remember it being a big accomplishment, as I didn't think such photos were possible without huge telescopes or big fancy lenses. I think with a bit of time and effort (same with a lot of things) you are able to push the boundaries laid out by your equipment.

Since then, I've managed to advance a little further into astrophotography, having captured photos of Saturn, Jupiter and more recently the Sun. As astrophotography is a huge hobby to get into, requiring a lot of patience (and money), I'm using this website as a way to monitor my progress and share my favorite photos, whilst sharing what I have learnt to help others going through the same process.

I've invested in a Celestron CG-5 GoTo tracking mount, which (once aligned after a few frustrating hours!) allows you to take long exposures of the night sky, by cancelling out the earths orbit effecting the movement on the stars. This is one of the first steps into capturing deep-sky objects (DSO's) which require longer exposures due to being so feint and not visible to the naked eye. A photo of the CG5 will be in the Equipment page linked here.
