A Pair of Galaxies

Picture saved with settings applied.

At last a clear evening!  Allowing Bizibilder to take this image of the two galaxies M81 or Bode’s Galaxy 12million light years away (the spiral one) and M82 or cigar Galaxy also 12 million light years away (also a spiral but seen “edge on”).  The two Galaxies really are close together and do interact gravitationally.  (1h 42m of exposure in 2min “subs” SW200P, HEQ5, Canon 1000D). (North is to the right). (I just swapped the photo for a better processed one – slightly less blue!)

Valentine’s Night Moon

Clavius aPlato a

A couple of mosaics of the Moon taken last Tuesday.  Both are four frames merged.  The telescope used was a 7” Maksutov-Cassagrain at f/15 and a Webcam.  Each frame is roughly the best 150 out of 900 frames taken. All are South at the bottom.

The crater Gassendi taken as above but with a 2x lens (Barlow) added.  Alongside is a drawing that Bizibilder made last year for comparison.

A few Moons and a different telescope

First MosaicFourth MosaicTerminatorThird MosaicThese are all mosaics of the Moon taken last night with a webcam and my 7” Maksutov-Cassagrain telescope.  This is a specialist scope designed for Lunar and planetry imaging – it seems to work quite well!  The seeing (atmosphere) was not all that steady but by stacking roughly 900 frames for each part of the mosaic Bizibilder seems to have managed to get an image.  Each “piece” of the mosaic is much smaller than those from the telescope that he has been using recently! Click HERE for a larger version of the “Terminator”!!

Final Image of M35

M35 4

Bizibilder has spent some considerable time faffing about with his collected data on this object.  This is the final processed image.  It is made from a total of 1h 16m exposure over two nights (taken from a total of 2h 30m – so 1h 14m was rejected due to image defects like trailing).  The final stacked image was processed in Photoshop to produce the version seen here.

You can see the open cluster of stars called M35 in the centre and the cluster NGC2518 in the lower right corner.
