Good one Rob,Good to see it was visible in the 8". Did you grab any images?
I was toying with the idea of trying for it in the 8" Parks but the dob base is a basketcase and I've no tube rings yet to mount it on the EQ6.
I needed that confirmation on the cores brightness.
I too found 60x to 120x..26mm unbarlowed/barlowed 2x gave the best views.Higher mags and the comet fades out.One of those events I wish I had some quality eps. Seeing here was absolutely brilliant and totally clear skies . Final views I had were around 12.30am in the 12" Parks and though it was lower in the sky I still had good views.

No images, I dont have a camera sensitive enough yet to image something like that. Dont think the old LPI will cut it lol

Yeah,bit much for the LPI
Tracking it prior to the event made it all worthwhile.Though I couldnt follow it as extensively as you Rob,conditions have been poor here, being able to locate it in a snap and knowing its previous appearance makes a difference.

I would have to agree with you there. I think tracking it over the prior month made a heck of a difference in noticing any changes. The only time I didn't follow it was through fullmoon phase for obvious reasons. I even observed the outburst on the 23rd & 24th June. which I feel had a bigger impact on it's appearence.

Over here in Brissie it is still pretty cloudy. Wonder if I will get lucky tonight. If so I will see if I can pick it up in the 6"f/5. So there was not much of a change in magnitude was there Rob?

Cloudy as here too! But it looks to be doing something in the east. We're still camped out in the yard. I'm want to try imaging Neptune and Uranus. Perhap if I pack up and move everything inside... hehehe

Here's part of a post from a yahoo group.

Unfortunately, I couldn't see the pseudonucleus pre-impact on 7/4 UT
due to twilight and clouds; I didn't make formal estimates of m2 on
7/2 but I feel it was around magnitude 15 or maybe a smidgen
brighter. So, a ~2-magnitude jump in m2 and an ~0.5-magnitude jump
in m1 (total coma brightness) seems about right. I saw about a 5'-
diameter coma. Too bad it wasn't the 5-magnitude jump that some
predicted (still couldn't see it in 8x56 binoculars).

I found it definitely easier to see, but I wonder how long that will last.

Last night, 4th july, we had good conditions at a dark sky location and we watched 9P, at mag 10.3, move a few arc minutes over the nearly 3 hours we observed it. Mainly used the 8.3" newt/dob at low power - 25mm ep. Amazing to think that increase in the m2 and degree of condensation (DC) was human made!!!

We easily saw a very starlike point of light in the larger diffuse 2 arc minute outer coma. Sometimes the central condensation varied in brightness a lot - even disappearing completly at times - hard to tell if that was real or just the affects of seeing - i would like to think we were watching varying levels of outgassing? LOL
anyway AWESOME!

The Kitt Peak blink was awesome, but what were the other blinks on the right hand side?

So overall there was not much of a change of magnitude. seems like comets will be comets and they are very unpredictable. but still i will see if i can catch a glimpse of it. Not looking good here though with all those clouds.....

Only the core was brighter Darren,which I thought made the comet more obvious.
Clear blue skies again tonight ,so Ill have another squiz and check its appearance.

Have you seen the movie on this site? Simply amazing movie from the camera onboard the impactor.

Also this site has some amazing pictures from the flyby mothership.

Oh I just realised Slice's link above has a great movie too, showing much of the same footage.
