Lovely image of M51 captured by CADSAS member Simon Powell. It’s from 60 images at various ISO and exposure times, but nothing over 2 minutes.
Another excellent image by our member Graham Caller. This time it’s IC443 also called the Jellyfish Nebula. It’s a supernova remnant in the constellation of Gemini.
Click the thumbnail image above for a larger version, though note that this has been reduced in resolution for the web. The original is even more impressive.
Last week was IC443 week. A couple of clear nights and I grabbed 8 hours worth of 15mins subs. Topped up this week with another 2.5 hours to improve the signal to noise ratio further.
Resultant image stacked in PixInsight and processed.
Oh! this was taken using an Ha filter.
We are hoping Graham will give us a lecture in the future, on his astroimaging techniques.
Our local friends at Ashford Astronomical Society are hosting the 2015 One-Day Spring Meeting of the British Astronomical Association at The Stour Centre in Ashford on Saturday 25th April 2015.
The theme is ‘Amateur and Professional Collaboration’. The meeting has been designed to help us find out how we can be involved in real science, working as an amateur with professionals.
There will be a series of talks throughout the day, on how amateur astronomers can work in tandem with national and international projects. The ticket price includes refreshments and a buffet lunch.

Here is a collection of astronomical images captured by our member Simon Powell. (click each thumbnail for a larger version of the image)
All were taken using a Skywatcher 200PDS telescope on an HEQ5 Equatorial mount, with a Canon 70D DSLR at prime focus. The deep sky shots were stacked in Deep Sky Stacker with darks, bios shots and flats. Post processing was done with Photoshop.
“Most of these were taken from central Maidstone, so light pollution is an issue, hence the Dumbell and Cigar have a lot of noise in the image. Now I’ve moved to Biddenden I’m hoping not to have that issue again!”
We welcome Simon to our area and our astronomical society!
Lovely image of the Orion nebula captured by Ted Pearson on 30 December.
Here is another go by Kevin Brown at M31, the Andromeda Galaxy. This time using sub-images captured in Canon 1000D RAW format.
This resulting image is made from 5 lights plus 1 dark, each of 180s exposure at 1600 ISO, stacked using Deep Sky Stacker software.
The settings used with DSS were rather random (more experience needed), so a better final result is probably possible…
The first decent picture taken from Kevin Brown’s DIY observatory. A very pleasing result after the build this summer, which was helped so much by CADSAS member Terry.
M31 Andromeda Galaxy plus M32 and M110. This is a stacked, colour adjusted composite image from .jpg lights (yes, mistake, should have been raw format).
Captured using Canon 1000D camera and Skywatcher ED80 refractor.
Image of the Sun captured on 7th July 2014 by our member Graham Caller. Comprising 80 frames at 1/4000 sec exposure, stacked in Registax software.
An image of double star Albireo in constellation Cygnus, imaged with the Alan Young Telescope.
Albireo consists of an orange giant of magnitude 3, together with the blue/green magnitude 5 companion.
It is good to see that our work on improving the Alan Young Telescope is now producing results, in the form of better quality astro-images.
This picture was captured on my Orion Starshoot Imager, with a run of 1 minute taking 600 frames and then aligning and stacking using “Registak” software.
In the same frame “Io” is peeking out from behind the planet, (just on the edge), at about 8 o’clock and about one jupiter diameter away is “Ganymede” on the same side. On the version I have sent you, Ganymede is dificult to see, but on the original it is clearer
