Image of M42 taken from Wimbledon Back Garden. Equipement: Celestron 6SE, 0.63 Focal reducer, Canon 1100d (no astro mod) 38 x 24s ISO 800. Image stacked in DSS with 5 flat frames (obtained using laptop). 25 x 24s darks. Image processing in Mathematica to obtain the required colour pallet. Final tweaks in Photoshope CS2.

Jupiter from Wimbledon back garden on 2/3/2013 with C6SE using Xcelx3 Barlow Processed in Registax ans Photoshop.

Lunar Mosaic taken on 17/2/2013 from Wimbledon Backgarden around 18:00. Taken using C6SE with x3 Barlow using Canon 1100D 1/25s ISO800. Assembled in photoshop.

Mosaic composition of the near full moon taken 26th December 2012 from Wimbledon backgarden. The composite is composed of 21 single images taken using C6SE with the Baader 2.35 x Barlow attached to Canon 1100D (ISO200, 1/25s). The image was composed in photoshop, with sharpening applied.No adjustment to curves or levels, just the neutral response of the camera is given here.

Taken on 28th November 2012 from Wimbledon back Garden with Webcam 1280 x 1024. Using Baader 2.35 x Barlow with the C6SE. Around 400 frames stacked in Registax6.0. Seeing ok. Decent view of the GRS.

Jupiter taken on 2 Nov 2012 using BYE with canon 1100d at ISO 800 1/25s exposure using the Baader 2.25 x Barlow and C6SE 500 frames stacked and aligned in Registax. Seeing poor - but some lucky frames added some extra detail.

This was the first attempt at imaging M31 through the C6SE using Canon 1100D at ISO3200 14 x 15s exposures at prime focus in September 2012. 10 darks @ 15s stacked, normalised and subtracted from each image. Post processing included the removal of most of the light pollution. Increasing the length of exposures is almost impossible. However in the process I built an alignment algorithm in Mathematica, based on the one used by NASA (and DSS) for plate solving, the results are decent for the quality of stacking and a big improvement on memory usage compared with the stock Mathematica algorithm. The exposure time can only really be solved with a better mount and a nice dark sky site !
