Hi guys! I saw the comet this morning, under moonlight, made it out at mag 4.4; dia= 15' and DC= 5. The coma is quite strongly condensed although no pseudo nucleus found! Not even through my 10" dob @ x31. No tail observed and was not naked eye under moonlight.!

Cheers!

Saw this one 2 mornings ago, and didn't bother estimating it as there was bright twilight and moonlight. Judging on how easy it was to see in binoculars under those conditions I would think mag 4.5 would be about right. I made some images but only the vaguest suggestion of tail. I might try tommorrow morning

About 5am, i was making visual estimates around 4:45am EST. Im taking the C8 out in the morning to get a decent tracked image of it and see what it picks up, the moon is bloody annoying though!

I have a few more i want to image, C/2008 A1 is around mag 9.5, confirmed by at least 3 other observers! But it will have to wait until i get back from Sydney this weekend!

I saw it for the first time at 5 am this morning. Easily visible in binoculars. I've just posted a couple of images in the Solar System Image forum.

Cheers,
Stephen

Nice clear skies just now, the comet was visible easily in binoculars and also just visible naked eye with the moon blocked by the roof on my deck. I have no experience with cometary magnitude estimates, so I won't go there

I had a look for it this morning between 5:30-6:30, but I couldn't seem to spot it using the 8x50 finderscope on my dob (don't have binoculars, unfortunately). I'm in the middle of suburbia, though, and my view to the East (which, from what I could tell, is where I should have been looking -- I'm still pretty new to all of this!) is particularly blocked, both by trees and buildings, and by the fact that I'm at the bottom of a hill.

Should suburban skies be okay for spotting it, as long as the view isn't obstructed?

It was easy to see with 20x80 binoculars this morning, and I wasn't dark adapted.

Hi All,

Took this image of the comet from dark skies on the Granite belt near Girraween NP on Saturday morning (28th June). Easily visible in 10x50 binocs., despite the nearby moon. Minus 5 deg C at the time!

Cheers,
Stephen

I saw Boattini this morning at Nambucca, naked eye (just), and easily visible through the finderscope.

Got some images through the ED80 will post later hopefully.

Well done OBM. Looks nice & bright with the 300mm. Would like to give it a go with my piggy-back 300mm kit lens next morning or so. What is the best time to see it you recken?

Hi Vincent, Your best bet would be around 4 am when it will be high enough to see it easily, you'll need a dark site to see it naked eye!
The comet is fading in mag so get out while you can!

Cheers!

Here are my morning images of Boattini so far.

First one from the 29th. I only got 5 exposures before the morning twilight turned the images blue. I slept through the alarm and started late No flats ICNR darks.

Second two from this morning, 1st July. First one is 11 exposures but unfortunately I forgot to change the settings from small jpeg to RAW No flats, ICNR darks. The third is 6 exposures in RAW. Flats + ICNR darks.

All exposures are 1 minute.

I can see a hint of tail (extending to about the 1:30'oclock position) but my laptop shows things brightly so you may not see them.

Tomorrow morning i'll try and get everything working correctly and take many more exposures and try to get the tail to show more.
