Just took this image of C/2014 E2 Jacques and just east of the comet is the 15th mag planetary nebula PLN 85+4.1.

@ John--nice pic!  There are some drawings in the Sketching forum that compare very well.

 

@ Tammy--with visual observers upthread and elsewhere on the Web reporting magnitudes of 6.8-7.2 and visible in small binoculars and finderscopes, it might be your transparency that limited your view.  8x30's might be a little too small.   Also, the comet's coma was getting broader--I read one report of 18'--so maybe the surface brightness is dropping.  I haven't had the opportunity to observe it myself since the morning of the 27th and the comet is supposed to fade but by reports it seems to be hanging on.

 

BTW, the comet will be passing right by mu Cep (Herschel's Garnet Star) tonight at zero hundred hours UT 31 August.  Photo op? 

 

Last night (Sept. 5th 2014) around 20:40 PDT, I tried with a little larger binoculars (44x95, instead of 8x30).

 

I found Deneb, about 5 degree higher., I was able to spot it in 10 seconds even though sky wasn't dark yet.

I sat on star chair, looking at the same view for half an hour until marine layers rolled in.  It was fun :)

I took this image very early this morning.   Still a fairly prominent green fuzz ball but the tail has all but disappeared from what I can see

in a histogram stretched stack of L = 10 X 60 seconds.  It has been fun following this comet as it races by clouds of Ha providing some

very interesting photo opportunities.

For those of your looking for C/2014 E2 Jacques in Stellarium here's an old faq post to add it (they used ISON as an example)

 

http://astropaz.weeb...stellarium.html

 

 

I'm going to use comet C/2012 S1 ISON as the example comet here as that is the one that is garnering the most attention right now.

1. Press F2 to open the "configuration" window. Under the
"Plugins" tab in the "Configuration" window, select "Solar System Editor". Under "options" at the bottom
of the tab, click the "Configure" button. A
window for "Solar System; objects" will open. Under the "Solar System tab" of
the "Solar System objects" window, click the "Import orbital elements in MPC
format" button at the bottom
of the tab. An "import data" window will open.

2.Under the "lists" tab of the "Import data" window,
Select the "type" as "comets"; select the
"source" as "download a list of objects from the internet"; under "or select
from the list" click on "Select bookmark" and select "MPC's list of observable
comets," and then click the button
"get orbital elements."
A list of objects found
will load. Scroll down and check the box next to
C/2012 S1 ISON , then click the "Add; objects". C/2012 S1 ISON will then be added
to your solar system. Close the Solar System
editor and Configuration
window.

3.
If you want to see where ISON will be in the
sky, you'll need to update your location and
time.

4.
Find ISON. Press F3 to open the "Find object"
window. Type in "C/2012 S1 ISON " and you should only see one choice "C/2012 S1 ISON " below the search box. Click the magnifying glass at the right of the
search box to lock in onISON. It will
automatically give you a view of the sky where
ISON is located.

So there you go, that should enable you to locate any comet you wish in Stellarium.
I hope this is of help to somebody.

Comet Jacques in Cygnus - from 09/03/2014.

 

C80ED f/7.5, Canon 400D

 

From 37 subs. 2 stacks were made, one aligned on the stars, the second

aligned on the comet head. The trailed comet was removed from the star stack,

the star trails removed from the comet stack, then the 2 were combined

with layers and a mask. Click for full-size.

Rich, PJ, and EJN--nice pics, especially with all those extra goodies.   :)

 

Rich, what is that in the inner core in your image?  The pn is just left of and partly behind the outer coma, correct?  I see something orange in the lower right of the core and a blue something just outside the core also lower right.

Yes that's the PN just to the left of the coma. The orange and blue items are problems with the image. I think because of movement of the comet but I'm not sure.
