    My latest image of MrG’s nebula shows that the eastern arm that was so prominent in the second half of 2013 is now fading.  The nebula now has an appearance similar to that in the early part of last year.

    Full sized image in the usual place…http://forum.oasi.org.uk/viewtopic.php?f=6&t=43&start=10 on the Orwell AS web forum.

    Why not get out and observe this interesting little nebula?  It is circumpolar from the UK at RA 20h 46m +67d 58m and associated with the star PV Cephei.  But be warned…it is quite small and faint.

    My latest monthly image of MrG’s nebula is attached.  The nebula continues in a stable state having had more or less the same appearance for the past 18 months.  But it could change at any time so is well worth monitoring.  The field of view of this image is ~ 10 x 10 arc minutes.

    The full size image and all my previous attempts are on the Orwell Astronomical Society web page: http://forum.oasi.org.uk/viewforum.php?f=6

    Only one more image so far as the weather in Australia hasn’t been very good recently!  This one is at the same scale, has the same orientation and the field star is also the same showing the motion of the planet.  Triton rotates anti-clockwise in this view and has completed about 2/3 of an orbit.

    More to follow when the weather improves!

    Mike.
