This invitation has just come in. Note the need to RSVP if you would like to attend. The attachment has: "You are cordially invited to the launch of 'Out of...
Hi If we ever get a clear night, there is a relatively bright comet about this month you might like to look for. It has the very catchy name of C/2006 VZ13...
I kept seeing these two from last week through the time I was out in the Southeast US. I had brought binoculars expecting amazing skies, but it turns out...
Hi Stephen, Was it Full Moon or New Moon? The skies in a really dark location at New Moon are amazing. At Full Moon it doesn't really matter where you are. ...
I managed to see them also, last Sunday evening. Using my 80mm refractor they both fitted easily into a number of eyepieces, but I most viewed at x28. Venus...
Yes, I also saw them. They were too low for my reflector so I set up my 4" refractor and they both fitted easily into the same eyepiece view. Very dramatic...
Hi Bob, I managed to bag this little 'critter' last night - after having experienced a few difficulties. My efforts on Friday night were frustrated, due mainly...
It sounds like you may have seen the effects of all the fires currently raging in the south and west of the US. They may well account for the haze in what is...

Hi, Gosh some stars came out to play on Saturday though a bit shy behind yucky transperancy. I got an hour on the North American Nebula, 6x10mins Ha exposures....
It could have been the fires, though I suspect it was just your standard high-level cloud. Apparently they were overdue rain, but it hadn't turned up, so the...
v1 appears best (on this moderately-bright LCD monitor anyway). It's odd, they appear almost as if they were taken with different colour filters, though you...
Hi Stephen, Thanks for the reply. Yes v1 is a linear stretch and a bit more contrasty than the others (edges are more noticeable). v2 is a DDP which is a kind...
whopps, I meant v3 is a mix of v1 & v2 not v3 & v2. I did it using layers in Photoshop but might give your suggestion a try too. Cheers Paul ... and green...
Hi Paul, Nice images. I think v1 and v3 are the better ones, though I personally perfer v1. Did you use your new Takahashi Epsilon astrograph to get these? As...
Paul/Julian I prefer V3 Like Julian, I had a good clear night Saturday so I guess the Oxford poor sky was caused by the fumes from all the burger vans in the...
Hi Bob/Julian, Think I'm favouring v3 now! Perversely, poor transperancy can mean good seeing! The lamppost in my backgarden is a good transperancy metre -...
I think my votes is for number 3 as well. Unfortunately I was at Henley on Sunday patching up drunken toffs got home just as dawn was breaking Owen ... Owen...
Hello all, My preference is for v3 as well. I was in London on Saturday night and saw a surprising number of stars, or was that the effects of too much cider...
It certainly is! I've a combination sight tube and Cheshire eyepiece and I still get some parallax effect trying to line up the crosses on the primary and...
Hi Julian, It has alignment marks on the secondary and primary which you can use a sight tube to line up. Still a bit tricky though, don't know if one of...
You can collimate a laser collimator, true, it's not generally necessary in my experience and they are very useful. For larger dobs I'd have said they were...
