From the album: Deep Sky Objects
M51 - Taken as a quick test of polar alignment and only an hours worth of data with a full moon, so I did not expect much. However it came out better than I thought. I will have another go at this one when conditions are more favourable and aim for 2.5 - 3 Hours worth of data. If you want more detail the astrobin link is: http://www.astrobin.com/250229/ -

NGC 4567 and NGC 4568 (nicknamed the Siamese Twins or the Butterfly Galaxies) are a set of spiral galaxies about 60 million light-years away in Virgo. They were both discovered by William Herschel in 1784. They are in the process of colliding and merging with each other. Taken with reasonable guiding but poor seeing conditions using a Skywatcher clear sky filter. For more details the astrobin link is: http://www.astrobin.com/248908/ -

Messier 101 - Pinwheel Galaxy Taken with reasonable seeing and the best guiding I have managed to date. I still need to get the guiding better but we are getting there. This is in monochrome only as I used a Skywatcher Clear Sky filter to deal with the light pollution. I'm very pleased with the end result all things considered.

NGC2403 - Taken over a couple of nights,both affected by cloud and my tracking was not as good as it should be, so the final result is not as sharp as I had hoped. -

Messier 1 - Considerably better than my previous attempts at this object. Taken with reasonable guiding, with reasonable seeing conditions (allowing for the light pollution). I had a restricted time window for this image caused by a combination of cloud and the target getting close to roofs of houses. I tried a different technique to deal with the light pollution, by putting a light pollution filter on the front on the filter wheel nose and then imaging as normal. The addition of the extra filter did not affect the parfocal nature of the Xagyl LRGB filters used. For more information the AstroBin Link is: http://www.astrobin.com/243527/-

Many thanks. I was hoping that it would turn out better, but the LP was so bad that if I stretched the image much more to show the full extent of the spiral arms the whole image started to turn yellow/orange. So I have pushed this one as far a my skills allow me to. I'm hoping to get out tonight for another target, which I may try a different tactic to try to deal with the LP, which is to use a LP filter in front of my colour filters and use slightly shorter subs (2-3 minutes). I will keep an eye out for your post/image. Good luck and clear skies! -

Messier 106 A spiral galaxy in the constellation Canes Venatici. It about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a super-massive black hole in the centre.

Messier 82 - Cigar Galaxy A starburst galaxy about 12 million light-years away in the constellation Ursa Major. Taken on an evening with a lot of light pollution, wind and cloud. Given the conditions I'm amazed at how well it came out. I only intended to do some auto guiding practice as conditions were so bad, but I decided to have a go at a target anyway. It looks like that practice has paid off. I had to throw a low of images away due to the wind, even some of the ones that I kept were a little suspect.

Messier 100 - First run with the Skywatcher AZ-EQ6 GT. Great tracking, the image was just spoilt by light pollution. I need to find a better approach to dealing with it. I did have this in LRGB and the image would be great if it was not for the yellow cast. Time to turn to the internet for further advice.

A supernova remnant in the constellation of Taurus. It is believed that this was first observed by Chinese astronomers in 1054. I was hoping to image this via my LX90 8" SCT and get a much more detailed and larger image of M1 but tracking issues forced me to drop back to using my ST80.

The Horsehead Nebula in Orion. I have always wnted to image this but unfortunately I ran out of time to collect any colour data and I did not get much luminosity as it went behind some trees. So I have tried to get the best I can out of 5, 3 minute frames. A target for another day I think. -

NGC 2903 is a barred spiral galaxy about 30 million light-years away in the constellation Leo. The colour data was not good so I have kept this in luminosity only. -
Many thanks. Yes I found some advice on various pages that gave some ideas on how to improve the ST80, £20 and a few hours work later I have a very much improved telescope. This was the first imaging run with the modified version and I'm delighted with the results for a scope that I was only ever going to use for auto-guiding. In fact it has made me completely re-think some of my approach to AP. -

M31 Andromeda Galaxy, taken using LRGB filters. No Moon, but heavy light pollution and a battle with dew. Plenty of tracking problems, the LX90 mount is showing the effort of tracking is this much equipment with a lot of errors. But I'm relatively pleased with the result. I have fine tuned the Orion ST80 and the end results seem very much improved over previous efforts so it looks like the hard work has paid off.
