had another casual squiz tonight - this time just bino's, put the 25x100's and the 20x80's on the manfretto tripod as well, and had a look with the eschenbach 8x56's handheld.
The viewing/transparency wasnt as nice as last night, might of been some cirrus or something? although I could make out plenty of mag 5.5ish stars in area NE - could be the farmers, they are starting to blinkin annual burn off before planting atm, causing it - gggrrrr - sky looked greyer
I was dissappointed with the view in the 100's which is unusual - the 20x80's was the best view, mounted on the tripod I could clearly see the cc this time - looked more like recent images posted, nowhere near as much tail visible as last night, but was also at a lower elevation than last night - geez its movin on out!
In the 8x56's it was pretty sad - just a little patch the winked in and out of view
anyway someone was complaining about the lack of visual reports on this forum - so here's my contribution! cant complain now?
anyway roll on the dark skies of SA's north :-))) (if we can dodge the pyromaniac farmers that is)
This is my one and only attempt to image a comet. It's in there somewhere ...... I think.
The problem is my northern view incorporates the glow of Brisbane and I only have a narrow window of opportunity through a gap in the trees. That plus the fact that I'm not really sure what I am looking for.
FWIW 17 x 32 sec exposures at ISO 200 taken on 27/4/06 between 11:30 pm & 12:00 am

doesn't quite go deep enough, I think you only have stars down to mag5/6, you need at least good exposure to mag9 but nice try

Doesn't go deep enough! ... doesn't go deep enough! ... what do you mean doesn't go deep enough? I'll have you know that some of those faintest dots in that image are mag 9 according to Cartes du Ciel. Only mag 5/6 indeed!!!! That does it I'm taking my telescope and going home
Seriously though. If I did manage to capture it what sort of size scale are we talking about here? How big would it appear at the same scale as the image I posted here? Is the tail fairly long?

Um ,err , i did that off the cuff, sorry but it didn't look that you got those mags, see earlier shots by myself and others for size indication
they is you look at the computer generated locality images you will see
OK worked it out now. "Smaller than a gnats nads" seems to be the correct answer then to "how big is it?" I was imagining something as large but a lot fainter than the comet (whose name escapes me for the moment) that was around a few years ago visible to the naked eye.

Comet Hyakutake. Scott Alder took a picture of it that made it to the cover of Sky and Space magazine back then.
Aaaahh, now I have seen the name it is kinda ringing a vague bell. Yeah that one.
Anyway, I was determined to find some trace of fragment C in my image. After pinpointing more accurately where it should have been and studying the images it turns out that for the first few images it was behind the tree in the bottom RH corner. So after removing those from framelist and then picking the best 6 from the remaining and stretching the living daylights out of the final histogram, I managed to get this. It is a crop of the bottom RH corner of the final image.
That very very very faint streak hidden amongst all the background noise could be it. It's good enough for me I can sleep tonight now.

I will beleive you, but fringe dweller had better verify this image!
How this one middy. An uncropped image of Cor Bor with Comet SW circled using a 50mm lens. Levels slightly adjusted to make the comet clearer. No cropping or other processing hence the lovely amp glow. This was taken on the 24/25-4-06
]Hi middy - pretty image of Corona Borealis - beautiful
heres my snp screen shot of the time you imaged - you indeed have the right spot - not sure if my orbital elements are exactly correct (may be out by 4 arc seconds or so) due to snp harvards single OE available (and its for the original SW3 before breakup LOL) I had to modify some of the ones available on the net - PITA! - had to do my own julian dates for perihelion, so not sure if thats the problem - anyway should be close enough.
There does seem to be a similar streak in the tree's near it - so cant say for sure anychance of stacking more for a deeper shot? i did stretch the hell out of it PS and there seems to be something there?
PS have included the obit path (blue line) for that moment in time - interesting to look at the other fragments on it - some slightly off the path
yep clouds/rain for us to hOughy hope it clears for ya mate (re Berts sexy lens!)
excellent image Paul, and two bits. Cloudy very cloudy here now after a spotless afternoon built the moment, only to disappear in a flash with this rotten cloud, maybe just maybe might be able to get some thing monday or sunday night!
cant complain now?
but nice try
That does it I'm taking my telescope and going home
