NGC7793 in Sculptor

[rodroger (Rodney)]

Here is a photo I have just finished processing of the Spiral Galaxy NGC7793 in Sculptor. This one is quite close to us at a distance of approximately 12,700,000 light years and is one of the members of the Sculptor Group of Galaxies.
This image was taken with my Meade DSI II Colour CCD on a 254mm Orion f3.9 Astrograph.
It is composed of 19 x 10 minute Monochrome Exposures
7 x 10 Minute Red
7 x 10 Minute Green
7 x 10 Minute Blue
Just to note my Meade DSI will not take images in colour mode any more for some reason and I do not have any imaging RGB filters.
The filters I used for the colour segment are common visual filters.
Red is Celestron #25
Green is Celestron #56
Blue is Celestron #80A

I have a friend in the USA who is currently purchasing a set of DSI Imaging filters directly from Meade which are on sale over there at the moment for $19.95 USD. These should improve my shots a bit with this camera, but would like to spend a bit of money on a high end dedicated deep sky imager in the near future which should greatly improve my fine detail a bit with better resolution.
The DSI still does a good job even though it is a bit blotchy at the bottom of the image.

Great capture Rodney, especially with such basic imaging equipment.

Imagine the results with a DSLR or ccd on your scope!

Good luck.

Great result Rodney, very smooth, colours work real well considering, nice going on that alone, and them stars are as round as, A beauty galaxy with also a 3D appearance from your processing,, Top show !

Thanks Guys for your Generous and appreciated comments. I am finally getting the best out off my processing methods. I must comment on the person who's tutorials I have found extremely beneficial to my learning curve, Donald P. Wade and his excellent Video tutorials which you can purchase from his site and are extremely reasonable as far as cost goes but has been a wealth of information for me.

I can imagine what I will be able to achieve with a high end CCD. I do not think I will bother getting a DSLR as they are not cooled and have no temperature sensor to know what exactly the camera temperature is.
Another thing I should mention is I have custom water & fan cooled my Meade DSI II Colour which greatly improves its performance.
