Had not seen a lot about this bright well placed Comet on the forum . 

 

Had observed last week from home with 13" and from a better location tonight /this am with 20"scope.

easy to star hop to , bright diffuse - broad coma -non stellar

 

Moved rapidly among the backdrop of stars over the night /am.  could not get any impression of the tail direction.

FWIW, here's an image I took in unfiltered light on Sept 15th. This is cropped to approx 9x9', 12" f/5 (at f/4) Newtonian, ASI1600MM, ~40 mins of 10 second exposures. Huge gamma to show the vague tail and nucleus. And (EDIT) in false colour!! Shows tail better.

 

North up. I think. If not then south up, but I think its north.

Just picked it up, got it last night, too. 20x80's and 4.5" 36x, 60x near andromeda galaxy. Got it about 1:05 after sundown , so not terribly dim but requires AV later, even. Green lp.

Perihelion is tomorrow.

Caught 64/P in the 13" on the 1st of Nov late night from home in this bortle 3ish zone.  

 

Need a little power, even though the evening was very transparent. 7mm at around was needed to absolutely confirm at  However better presentation in the 12mm for 125X   Non stellar, but this was for whatever reason tough to find that night. 

 

may have been the field stars behind the comet.  There were 3 Comets I observed that night/am including 38/P and 21/P later in the wee hours.

 

Ive mixed them up ?  Was very tired . In my notes 38/P was improving from last observation  so I think correct. Spent about 6.5 hours observing (total) that night and next AM

 

  I believe I am in similar skies as above post #3

Yeah 64p was in front of a little cluster of stars Thursday night /Friday morning so I went back out to confirm last night. I thought the nebulosity might be in with the stars.

 

There's no object there , though, I don't think, but yeah, made it a little harder. Last night wasn't too  bad though. 

 

That star field gave me fits too!! Weird.  I haven't been out much, though, lately. That much elevation is hard with a dob, too, maybe that was it?

naw Mike ,yes  it was the star field - not the elevation IMO .  Waiting helped confirm the object.

I think that came out wrong I meant me lolon the altitude.  I'm not an astrophotographer really, but you might be able to see it. Had to resize, but you might see the little green dot. Upper center

Sorry couldnt resist playing with your image! Flattened the background ('lines to equal values' in FITSWORK) and applied some photoshop curves to brighten it up. The full res must be a really nice shot I think, got potential!

Galaxy-Mike's image...and Happylimpet's enhancement thereof...are quite useful in giving me some idea of what to look for through my binoculars the next clear night that comes my way (hopefully tonight).

So, thanks to them both! smile.gif

I observed the periodic comet 64P/Swift-Gehrels this morning using the 17" f/15 classical Cassegrain at the Naylor Observatory.  The comet was quite faint, given the observatory's orange-zone skies.  I used magnifications of 116, 162, 185, 216, 259, and 324x, with the best view being at 259x.

Not long ago I observed Comet 64P once again with the 17" classical Cassegrain at the Naylor Observatory.  The transparency was a bit better than on Saturday night/Sunday morning.  I used magnifications of 116, 162, 185, 216, and 259x, with the best view being at 216x.  The comet was faint and diffuse.

I managed to observe 64P this evening around 7.30 GMT in a 4" rich field refractor, it's quite faint though. It was a ghostly glow at 50x and also visible at 33x . Sky Safari has it's location spot on for those wanting a view.

Here is a photo of 64P from a few nights ago. 3 frames x 30 sec ISO1600.

I caught 64P with my 10" Dob on the evening of November 8th during an outreach star party. I was busy with brighter objects and the comet was close to a field star, so I didn't do a sketch. I decided to track it down again on the morning of November 18th after moonset and before the comet got too low. Once again, there was a bright field star involved in the coma, but since I had other objects to observe and the comet was headed toward local lights I decided to do a sketch. It kind of looked impressive, the 11th-magnitude star masquerading as a nucleus at the head of a parabolic coma. The coma was diffuse and fan-shaped with a slightly brighter condensation that slowly moved past the star as I was viewing it. An Orion UltraBlock filter improved the view.

This one quite bright and up in dobs hole early on.  Good finder stars nearby.

Best at 125X in the 13".

 

A slight haze. Wanted to stay up for 38/P as well but too sleepy.
