JPEG compression has not done the image justice. Bit blocky compared with the TIFF. -

Taken from the back garden on 8/9/2012 at 02:26 BST Using C6SE, with Baader 2.25 Barlow, with a 20mm EP in the extendable eypiece projection Kit. Canon 1100D ISO 1600 1/8 s Seeing poor. -

Taken on Wimbledon Common 30/8/2012 C6SE with Revelation 32mm at near full extension. Atmospheric stability very good, transparency not so good. Canon 1100D ISO 100 1/250s - Colour curv adjustment to get that sepia look Bit of an edge effect - only one edge has decent focus. -
Planetray Image Stacking Mathematica Jupiter 20120811
Hugechris commented on Hugechris's gallery image in Member's Album
The image was taken on the fly afer an opportune moment (being up to late). The scope still needed more cooling, so there is a slight coma effect on the image. Increasing the overall image size by a factor of 2 will squeeze out more detail. -

Planetray Image Stacking Mathematica Jupiter 20120811

From the album: Planetary Images
Image formed from a stack of 5 images taken from backgarden around 4:30 am on 11/08/2012. Image taken using C6SE, Seben zoom at 8mm with 1100D at ISO 400 with 1/13s exposure. Seeing poor ~ 2" Image has been processed in Mathematica using custom stacking routine and deconvolution. This image should be compared to the standalone image. -

From the album: Spectroscopy
Raw diffraction spectrum of Vega using the SA100 imaged through an unmodified Canon 1100D and the Celestron 6SE at prime focus. The SA100 was approx 90mm from the sensor. Exposure time 1s at ISO 800. Spectrum looks a bit overexposed and there is light leakage across the sensor. However there is something there. -
From the album: Lunar Images
Lunar Images that have been processed using Mathematica. This image demonstrates the impact of a custom sharpening filter that operates on the detail levels of the wavelet transform. The image is then rebuilt from the inverse wavelet transform giving the sharper image on the left, with no issues with increase in noise. -
Mathematica Image Processing Example
Hugechris commented on Hugechris's gallery image in Member's Album
Need to click on the image or get really close to see the improvement. Lossy jpeg has removed much of the fine detail improvement, but the difference are clear if you get close to the screen. -
From the album: Lunar Images
An Example of Image processing in Mathematica, taking the original small sample of the IMG_2541 from left to right original, Gaussian deconvolution using TotalVariation, with MeanFilter denoising, then sharpening at different scales 5 pixels, 10 pixels and the last is a weighted addition of the 2 images. The further processing adds considerable detail to an image already processed in Canon professional. -

The moon from Wimbledon Common using the C6SE with the Baader mkIII zoom at 20mm. Image focussed only in the central region. Image processing - unsharp mask in Canon Image professional. Seeing very poor and windy - this was a lucky shot Canon 1100D ISO200 1/50s -

Saturn on 18th June From the second set of AVIs from Canon 1100d 1min (~1400 frames) Pretty poor quality after alignment and stacking in Registax 6.0 Taken using the Seben 8-24mm zoom with a 30mm extension tube. Usual poor seeing from London. Have since checked the collimation of the scope and discovered it can be improved.
