2007 Oct - Nov - R. Stankiewicz - Comet 17P_Holmes-labelled

Speaking of Comet Holmes and  visual reminder of things passed.

These images were taken from my front yard with a little Canon Digital Rebel XTi camera and
Sigma 70-300mm lense @ 215mm, tracking on top (piggy-back) of my ETX telescope.

Settings were ISO 1600; f/5; 30 sec. exp.

Now this was a naked eye comet!

Just wanted to share my best image of this early a.m. (3:00) of Comet 46/P closest approach
in 70 years and today set history as this comet joined the ranks of only 9 other comets to come
this close to Earth (today's was about 11 million km). The clouds were a challenge today, but 
patience paid off.

It is naked eye now, but still need half decent skies.

2020-Apr 12 - B. Hardy - Comet 2019 Y4 Atlas Demise

It looks like C/2019 Y4 (Atlas) is indeed fragmenting and dimming in the process.  I have included two 
images of the comet taken 6 days apart (April 5 & April 11).  Both images are 7 second exposures with all 
setting the same.  The most recent image is clearly of a lower magnitude with a much extended nucleus 
than the earlier image.  In addition, the April 11th image was taken without the Moon interfering, while the 
earlier, brighter image, was taken with an 87% illuminated Moon high in the sky.  On a positive note, the 
extension of the tail seems much longer in last night's shot.

Anything can happen, but it appears that the nucleus of C/2019 Y4 (Atlas) is breaking up and unlikely to 
brighten further.  The likelihood of it surviving its encounter with the Sun at 0.3 AU (45 million km) in late May 
is unlikely.  Very disheartening.

Comet C/2017 T2 PanSTARRS

In keeping with the social distancing philosophy I have set up in the end of my driveway. It only has a really clear view 
to the north so normally that would not be very encouraging but with comets C/2019 Y4 and C/2017 T2 cosying up to 
Polaris I was very well placed. These two photos were single exposures (30secs. & 15secs.) taken at the prime focus 
of the LX90 using the Sony a6000 with an f/6.3 focal reducer, FOV approx. 64'x42', then cropped to about 30'x30'. 
The stars are down to Mag. 16 or maybe a bit more, my star chart only goes to 16.5.

2020-Apr 6 - B. Hardy - Comet 2019 Y4 Atlas image annotated

Despite the Moon at mag. -11.8 and 94% illumination,I spent some time on comet C/2019 Y4 (Atlas).  The 
comet has brightened since last I looked, now at magnitude 7.5  It is located in the constellation 
Camelopardalis and is circumpolar.  Located 1.03 A.U. (153.9 million km) from Earth with a 110,000 km 
coma and obvious tail.  It is a fast mover at 1.61 arcseconds/minute.  

I have included two images.  The first image is annotated with the magnitude of an interesting grouping of 
stars. Both images are 7 second exposures of 40 stacked images, representing 2 minutes 40 seconds 
total integration.  Zoom in and notice the dim star close to the nucleus within the tail.  Compare the location 
of this star with the next image to see the motion over a span of just 12 minutes.  Orbital dynamics in action!

 Further brightening should continue as it approaches the Sun.  Perihelion (closest approach to the Sun) 
occurs on May 30th.  Predictions place it at 0 magnitude at its brightest.  It has a long way to go to reach 
that brilliance, but what a sight it will be if it does.  I am looking forward to when the Moon gets out of the 
way in a week or so,

2020-Apr 8 - M. McCarthy - Comet C_2019_Y4 Motion

This is an animated Gif of the comet C/2019 Y4 on March 27 2020 from the North end of Peterborough 
(1km from Walmart and Canadian Tire) . Camera is a Mallincam Extreme and Idas D2 filter. Scope is a 
C14 on a G11 mount. No offset tracking of the comet just sidereal rate.  Its 200 x 30 sec images  made into 
a gif using GIMP.  Local time was from 9:53pm to 11:37pm. It was nice and clear temps approaching 2C 
and humidity 93%.

Comet C2019 Y4 ATLAS

I was finally able to capture comet C 2019 Y4 Atlas last night.  The comet is high in the 
constellation Ursa Major right now.  The following data is from SkyTools4 Visual Professional 
Edition, the software I am using to control my TMB 175mm f8 telescope.  At the time 
of my image comet C 2019 Y4 Atlas was 1.1 AU from Earth (1 AU = 150 million km) and 
is moving very quickly at 1.76 arc seconds per minute.  It was magnitude 8.2 with a coma 
diameter of 2.3 arc minutes.  The actual coma diameter is 110,000 km and shows a 
subtle tail of gas and dust.  It will reach perihelion (closest approach to the Sun) on May 30th. 
Our best view of this comet comes on April 24th and is predicted to reach 0 magnitude.  
That will be very impressive if this comes to pass, although it is no slouch right now.  The 
comet is brightening quickly, but it is also moving lower in the sky.  Catch it while you can!

The attached image has an exposure of 12 seconds and is a stack of 30 frames performed 
within the capture software.  The camera is a MallinCam SkyRaider DS10cTEC.  This 
image is a screen capture with no post processing.

C/2017 T2 Panstarrs

A few nights ago I tried to grab some images of some of these comets up in the northern sky and I managed to grab 
C/2017 T2 Panstarrs in Cassiopeia. My image is not near as impressive as your or Brett's of Y4 Atlas, but I snagged 
mine with a Canon D6 (DSLR) camera and a Canon 200mm lense from my front driveway. I have to admit I couldn't 
see the comet (mag. 8.5), but I framed my viewfinder in the area the comet was to be that night and I got it. The 
attached cropped version of my image is what I got.

Brian McGaffney
Taken  from the Nutwood observatory of Comet Garradd as it
neared star cluster M71 To show detail of the comet and M71 
without the movement blur of the comet, the camera was set up to
take quick LRGB images and re position the comet backwards against
the digital frame board. Best viewing is done when saving image to
desktop, then use resident viewer.

Comet Catalina

50mm shot at f/2.8 and about ISO 1250 for 20
seconds.


Ever since January 1st the Comet Catalina has been scooting 
up the side of the constellation Bootes and will be heading 
for the handle of the Big Dipper in a few weeks. It boarding 
on naked eye vis, but an easy find with binos. In my 20X80's 
it just popped. It shows up as a good sized fuzz ball, but the
tails are not distinct. The 200mm close-up shot shows it best, 
as to what you can expect. The dust tail down to the lower 
right is hinted at with averted vision, but don't hold out much 
hope for the upward pointed ion tail.

Image of Comet ISON taken 
October 12th 2013 here at the Nutwood 
Observatory. There have been quite a 
few morning that were clear over the 
last week, but fog in the higher altitudes 
here made taking close up images of the 
comet not possible. However, this morning 
at 4:30 AM it was less misty and we were 
able to take the image. 

When taken this comet was at Magnitude 10 
and moving very fast. Images were taken with 
a 14 inch Astrograph, guided and with an 
Apogee 16 M CCD camera.

Total aqusition was about 20 minutes, however, 
processing time was another story.
