Quote:I thought I saw it, but am somewhat less confident now that all the negative reports have come in. It was about where it should have been, a short, very well-defined stub, sort of like I saw McNaught a few years back, but pointing hard to the south, a little before 10 o'clock on a clock face, relative to the horizon. Also, unlike a contrail, it set behind a hill rather than simply dissipating, fading, or blowing toward us with the wind.Hard for me to judge size or brightness, because I couldn't see it with the naked eye and didn't have time to measure it relative to objects on the horizon. Saw it for only a few moments, within about fifteen minutes of the sun dropping behind the distant hills.Anyway, I'll be trying again from the same spot tomorrow, so if it's clear, I'll know for sure then.

Quote:and here is another frame (extreme crop) showing an airplane passing just below.
Quote:well, you may be right but i have multiple 20 second exposures where this object appears in the same spot. in fact, the detail shot with the airplane below is a separate shot from the one above.Jay

Quote:Its not really supprising that no-one is seeing anything - a case of pulling trigger far too early. E.g. last night Pan-STARRS would have been 1/2 degree above horizon at start of nautical twilight at 40 N
Tonight its 2 degrees at start of NT, day after is 4 degrees at NT, then 6, 7, 8, 9 and 10 degrees on 15th March
Certainly not - just everyone looking when its improbable to see.
I recon first observation below 40 N *might* be tonight - low probability. Better chance the day after - otherwise 12/13th will be much easier as very very thin moon is nearby

Quote:I remember when we passed off Comet McNaught to you southern hemisphere observers back in January of 2007 it was bright as a flare through binoculars during twilight. I know it's not your fault you couldn't do the same for us with PanSTARRS.
Quote:Well I'm nuts!
Quote:Quote:and Ive never seen a comet without a comaTheres been a few - recently C/2011 W3 was almost comaless. You can't dismiss this just because you haven't experienced it. Its better to dimiss this if someone else has a validated image on the same date with a coma
Quote:My friend here unfriended me on Facebook over it then deleted two of my four images on his Astronomy group there and followed that up with saying I had posted doctored and phony images.
Quote:...The fact that you documented your observation and publicly shared the image should be a clear indication that you're open to--welcoming of, in fact--others' objective analysis. If it turns out to have been an atmospheric event captured in your photo, you will still have contributed something of value. Negative sightings help us to better understand what is required for a positive sighting.

Quote:Quote: ...in the straight through configuration that I had with my 6" refractor with no diagonal installed, my bearings are completely screwed up as to which direction is which...I panned to the right and saw Mars......Ralph Ralph,I got to thinking about this and a refractor with no diagonal would have zero reflections and an upside down view (like a Newtonian reflector). Wouldn't you have had to pan to the left to see Mars? Were you using a GEM or alt/az mount?
Quote:Yeah, sorry, these shots aren't the comet. The overwhelmingly bright part of PANSTARRS is the tiny, intense inner coma and if your images show just a tail it isn't the comet. Same for binocular & naked-eye views. As the comet moves into darker skies over the next week, visually look for a faint 'star' to pop out, in the right position. The tail will reveal itself as the sky darkens. It is visible in binoculars before it is visible naked-eye of course - if you can locate the comet (think 'star'!) with binoculars then this significantly helps locate it naked eye. It's still just visible from the south and a friend in NSW, Australia, successfully saw it again tonight. I haven't seen it since 6 March due to cloud. My "farewell" shot from that night is attached.Good luck - hope it puts on a good show & I look forward to your reports & images! Cheers - Rob
Quote:OK, Ralph. And I didn't really write what I meant clearly. You would pan to the right but in the ep view, objects would appear to travel in from left to right (since it was upside down).
