Comet C/2007F1 leonos

Has anyone observed comet C/2007 F1 LEONOS yet?
We have had clouds every day for the last five days so no joy here

Thanks Kearn, it was just a general enquirie as I had seen no posts and with crap weather we are having on this side of the continent, thought someone
might have sneaked a look in between the clouds.

It sure is frustrating, I agree.

Purchased my new eyepiece set 2 weeks ago and still haven't used them Now it's the long weekend and I was hoping to pull an all-nighter but I doubt that. I'm spewing

Last night before tea margaret and I decided to give C/Loneos F1 a go.

Clear skies, looks good. After sunset find Antaries, go down about 12 degrees and of to the right about 5 degrees and the it was sitting next the star Graffias (just left of)!

As the darkness slowly set in the view got better. The comet through 30X100 binos (I just love these, great buy) was quite good, an elongated smudge and faily faint but easy to find and see. Margaret was impressed and requested that we get up to see C/Holmes, shall post these details later.

thanks for report Wade, sounds promising! i hope to see this one too soon

btw Michael Mattiazzo's website has a space observatory pic of loneos

dont forget its a great place for charts and up to date info for comets at mid southern latitudes - i always keep an eye on it, he does great work!!

edit: boy it sure does go by some juicy bits of the sky!!

Yes, we are lucky this year. Three naked eye comets, although Loneos just.

I did not get a chance to spend much time at the eyepiece but I assume the smudge was some of the tail.(I am a beginer concerning comets).

Monday night(5th 11 2007) about 8:15pm WDST seems to hold good potential according to StarryNight. Antares, M4 the Cats Eye Globular and Loneos F1 should all fit the FOV for the 30X100 binos. Also I plan to set the scope up as well.

Fingures crossed!!

There was a club meeting last night so we made a group effort to track it down. It was finally spotted to the left and above Graffias. Reasonably easy to see in binos, a bit a like small planetary nebula. In a 8" scope it reminded us of a globular cluster and there was a little discussion on whether we had picked up M80 by accident but in the end it was decided that we where too far below M80 for there to be a mix-up. I hope this gives some idea of what brightness it is at at the moment.

The person who first spotted the comet was the one who also reckoned there was a small tail visible in the scope. Due to the comet being low to the horizon and a lot of people about I didn't get a really good look at it before it sunk too low. But I suppose as it gets higher each night it might be easier to tell.

Managed to get aquick view at about 18:30 low down and through some cloud, also still in twilight
Using the 16" and 13mm nagler was slightly bluey white, only had about 2 minutes observation time before the clouds covered it for good.
I waited all night for a look at comet Holmes, Through the 16" it is umungous, must be at least a third of a degree in Diameter, again only a short time before the clouds covered it.
Called it a night at 00:20.
A rewarding night but very frustrating.
I set the 8" sct up to take some pics but it went into the clouds never to come out again.

Ok i seen it tonight but only through binoculars, i imaged it with a tripod shot....

If you look closely you will see the comet and a long thin tail which has trailed in the image, just under sigma scorpii

I didn't have time to drag my scope out tonight, so i took heaps of tripod shots!

60 sec exp @ f/5.6 @ 55mm

I only have the 18-55mm lens for this camera, incidentally does Mogg Adaptors do rings to adapt Minolta Bayonet to EOS??? I have a 300mm Minolta (japan) lens i could be using!

Cheers!

wow you've done it again OBM!! you have at least a 3- 4d tail there. so far, sure is a pretty 'typical' comet. like recent Pojmanski was too, tail lengths seem pretty common in this sort - shes a 10 to 20d blue ion tail with a longer guided digital widefield shot then, and maybe 5/6/7/8d in binocs from dark skies, no dust so dark skies are mandatory? less it does something out of the ordinary?
interestingly going through that part of the sky might not be the photo op you would normally think it is, it is one of those rare bright ones that goes through the brighter milky way.
i remember when Comet C/2001 Q4 NEAT was in canis major, tail in/thru puppis, early may 2004, then seeing it out of the milky way a little later, i couldnt believe it was the same comet. the contrast you lose with ion tails in the MW is substanial, even visually - not that its going stop anyone or me just had a flashback to it thats all lol - i think it happened famously with halley's last time round of course.

oh to live in the countryside *sigh* its a rather big hassle to get to really dark skies from where i live for me
keep em coming OBM
