Abell 1367 Galaxy cluster in Leo

Taken las night whilst trying out 10 min subs with mt ED120APO and Canon 1100D.  this is the result of 20 x 10mins = 3 hrs 20 mins total exposure.  Bias and flats included.

I did take this object last year with 5 min subs but this one is far deeper - easily to mag 17 or more.  I have marked over 120 galaxies within the image.

As a bonus Comet 32P Comas Sola is dead centre of the frame.  this is Mag 14.94.

M81 and M82 21 February 2015–10 min subs with a DSLR!!

I thought I'd try some 10 minute subs with my 1100D (I invariably use 5mins for DSO imaging) just to see what would happen.

I was expecting all sorts of problems but these did not materialise!  The only issue I did have was some slightly egg shaped stars after about an hour of imaging - I can only assume this was due to the scope being in an almost vertical position and something somewhere moving!  (I did check and there were no cables etc snagging).  The PHD trace remained dead straight but the stars became elongated by a couple of pixels.  That left me with an hour of useful subs.

So  6 x 10 mins with a Canon 1100D at ISO 800.  ED 120 APO on an EQ6 guiding with an ST80 and QHY5/ EQMOD.   Processed with flats and bias only in DSS and PS CS5:

Lots of tiddly spots today - 3 main active areas that seem to be developing slowly.  Also the first time back in the observatory this spring so taken with the 120mm APO.

M81 and M82 18 February 2015

Tried these two galaxies with my unmodded Canon 1100D.  3hrs in 5min subs with flats and bias - No darks.  ED120APO, flattener, EQ6 guided with PHD. Stacked in DSS and finished in PS:

18 Feb Sun

Today's effort - seeing was better than yesterday.  There appear to be a few new active areas forming and/or rotating into view:

Clear skies at last and a very quiet Sun.  Seeing was only fair.  50/200 frames with the 120mm Achromat and Canon 1100D at ISO 100 and 1/1250sec:

Showing the phase.  ED120 APO, ASI120MM mono, 2.5x Powermate, 2000/10000 frames stacked in AS2 and sharpened in R6.  RGB image combined in PS.  It is very rare to see any surface shadows on Venus and certainly no details!  Click image for full size:
