@ Portmac, the comet rises just before twilight in the east, below Sagittarius. I think there's links earlier in this thread and in the observing section that has finder charts etc. Um.. thread here http://www.iceinspace.com.au/forum/s...ead.php?t=6754

There was another thread in beginners but I can't seem to find it.

Thanks Circumpolar, the skies have been very cloudy actually and strangely parting where the comet is for 20 minutes or so. I'll eat my hat if I get a shot this morning though, it's been raining off and on all night.

I see there's a luna intruder in the morning sky now. Here's a pic taken through the same scope I use to shoot the comet with at prime focus (5.5 inch f3.64). Normally I wouldn't use this scope for the moon but this gives an idea of field of view for the comet pics.

Anyone know of any good hat recipes?

Barely 10 minutes this morning and I think it rained through part of the frame. Moon shower?

I'm not real happy with the image quality but it's better than nothing. 200mm lens pic. Doesn't seem to matter which lens I use the tail goes right through the frame.

Difficulties aside Comet Pojmanski is an excellent photographic target but visually it's a bit disappointing. I remember T7 Linear as a beautiful comet with a long easy to see visual tail in small scopes but this one is just a fuzzball at best and amost star like at low power.
More comet magic from the bedroom window!! well what can I say you have surpassed even yourself in this effort B2catcher. I am seriously impressed! Its made its apparition all the more enjoyable, appreciate that

T7 was a very nice comet, exotic even, remarkable colour!! and loved the classic anti-tail earlier on. telescopic views were very good on it too, better than most are :-))
i remember I got more length in the anti-tail in the 8" dob than we did photographically! I think? around 2º or a little more? from memory? from a dark site.

Kevin did you catch C/2000 WM1 after its outburst in early 2002?, now that was a very serious eastern/morning comet the best ever telescopically for me, that and C/2001 A2 would be my pics morning comets in recent times.
PS what is the FOV of last pic?, cheers.

Completely missed C/2000 WM1 and C/2001 A2. What a pity, they looked like nice ones. I went through a bad period of health from 1998-2002 and missed most of the comets of that time.

Not sure of the field of view through the 200mm lens, a couple of degrees? It easily fits in Orion's sword area.

Well I've got nothing else to do at 4:00am.

The weather is getting worse. I've processed it out but there's a lot of high level cloud in this frame.

109 frames - about 4 minutes worth with a 135mm f2.5 lens. And again I see the tail goes right through the frame.

I see the comet is taking a dive in elevation. Looks like I'll only have it for about another week.

I wouldn't exactly say it was clear Mike. This is the cloud this morning in the direction of the comet. I'm just trying to shoot through the gaps.

The comet is still there but this cloud is so frustrating. I can't get long enough gaps between clouds to take a nice pic.

5 inch f3.64 scope again. It's below Venus this morning.

This is the first time since Feb26 I've been able to get anything. Just looking out the window now it's completely overcast. Plenty of cloud through the shot as well but I got something.

Long thin tail in the 5.5 inch.

Thanks. It is getting low but also rising in a spot where the treeline is lower. I'm guessing I'll have it for about another 4 days but by then it will rise with twilight.

Might be the last I see of it if the weather map is anything to go by.

Thanks Mick.

I've been tryiing to correct the soft images from the 5.5 inch cometcatcher scope so last night I turned the corrector plate around and the images are 100% better. I must have put it in the wrong way when I cleaned it! Oh well a bit late now.

very interesting Kevin when you put it all together like that, looks like it confirms a conjecture by some comet guru's I read.
If you look at frames for feb 18, 19, 20, 21, it seems posssibly that there is a jet/streamer outgassing from a fissure rotating with or being influenced by the nucleus rotating/tumbling on it's axis over days - I could be way off?? -- just a possibilty maybe, anyway looks great

I think I see what you mean, especially for Feb 20-21 where the comet appears to have twisted around.
