The images on this page were taken through a meade LX90 using a bog standard webcam.  An AVI movie was shot - and the resultant frames stacked to help reduce noise.

 
  • The Sun
This is a first light for my new Coronado PST.  I managed to capture a few AVI's through gaps in the clouds and processed them into this image.  The prominences were captures at 1/250 sec and the surface detail at 1/1000 sec.  The resulting AVI's were stacked using registax and processed/layered using photoshop elements.

Coronado PST + toucam pro2.  IR blocking filter and 2x barlow.

Processed above to bring out more detail.
Same setup as above - A series of 1/250 sec exposures (gain at 50%) stacked in registax and processed in photoshop.  Captured on 19th March 2008
As above but deconvoluted to try and bring out more detail.  Each image in the mosaic had 50 iterations of maximum entropy deconvolution applied with a PSF of 2.0 in Stellar magic Freeware.  I also performed a linear histo stretch on each.
  • Jupiter
Stacked image of Jupiter.  Notice the dark spot to the bottom right.  That is the shadow of one of Jupiter's moons eclipsing Jupiter.
A raw frame from the AVI movie that was used to create the above image - notice the lack of detail and considerable noise.
Another shot of Jupiter - captures in the same way as above but taken on a different day and at a different magnification
 
  • Saturn
Stacked image of Saturn (~150 of 300 1/100 sec frames)

Processed using Registax and Photoshop Elements.

 
  • Moon
A panorama created by stitching multiple stacked frames together.
  • 1999 Solar Eclipse
This shot was taken just before totality.  There was fairly heavy patchy cloud that day (Austrian/German border) - and so we jumped in the car and chased the gaps.
After catching a gap in the clouds - we jumped out of the car and set the telescope up with about 1 minute to spare.  This shot was taken using a compact digital camera in the middle of totality.  Some details can be seen in the corona.
  • 2007 Perseids
A single Perseid captured on 13th Aug 2007.  This shot shows the constellation of Cassiopeia and a hint of M31 can also bee seen
  • Comet 17P/Holmes
Taken on 29th Oct 2007 - this shows the flare up of Comet 17P/Holmes.  This is a median stack of 13 x 2sec iso1600 unguided using a Canon EOS300D attached to a 10" Meade LX90 fitted with an F6.3 focal reducer and a 12.5mm eyepiece.  Stacked in DeepSkyStacker 2.6.1, touched up in Photoshop elements and RL deconvolution using Iris 5.41.
As above but simply stacked in Registax 4 and adjusted in photoshop elements.  No dark subtraction and no deconvolution.
