Broadcasting on Night Skies Network

admin — Thu, 26 Aug 2010 08:03:51 +0000

I’ve been broadcasting (channel name ForthimageUK) video images of the moon and Jupiter the past few nights on Night Skies Network. It’s been great fun sharing the views with people around the world; some in places where it’s not yet dark, others with poor weather.

Worth a look if you get a chance and you can chat to some fellow astronomers round the world. The moon’s been too bright to do any astrophotography so this was a fun diversion. Thanks to all who visited and thanks to Jim Turner(?) for setting it all up.

M71 and new LPR filter

M71 globular cluster in Sagitta.
Used a Skywatcher LPR filter for the first time with this one. It’s not as aggressive as the old Lumicon DS filter. However, it doesn’t work so well on nebulous objects. M31 showed a large LP halo around it with this filter.

M27 Goodbye coma!!!

At last I have got rid of the horrible coma in the 200P. A Baader MPCC has done the job perfectly- well at least as far as I can see. Highly recommended! M27 looks better too and much more detailed than my last attempt at it.

Planet “Art”

Still in the twilight zone here in Scotland so had to resort to playing around with Photoshop and creating some artificial objects. Can you spot the rust texture?
