MOON VENUS CONJUNCTION

Location:  Front yard, Little Lepreau, NB, Canada

Date Time:  December 28, 2019 1900-1910hrs

Weather:  Clear, cool -2C, no wind, partly cloudy.

Equipment:  Canon Rebel T3 with 75-300mm lens, tripod.  Images processed with PhotoShop.

Attendance:  David McCashion

Objective:  To view and image a close conjunction of a thin, young crescent Moon and Venus, after getting a call from someone who said the Moon was looking amazing.

Report:
  • Heard from someone that there was an amazing Moon in the sky and that I should take a look.  Went out in the front yard and a very thin, red, crescent Moon was low in the west with a very bright Venus over it.

CHRISTMAS COMET AND A FADING STAR

Location:  Front porch, Little Lepreau, NB, Canada

Date Time:  December 26, 2019 1830-2200hrs

Weather:  No wind, to slight breeze, bitter cold, -12.5C, 64% humidity, mostly clear to clear, no dew.

Equipment:  Canon Rebel t3 connected to telescope at prime focus and with an 18-55mm lens.  Images stacked with DeepSkyStacker and processed with PhotoShop.

Attendance:  David McCashion

Objective:  To image Comet C/2017 T2 Panstarrs and to view and image Orions alpha star, Betelgeuse as it has been reported to be diminishing in brightness since October of this year.

Report:
  • Aligned telescope on four stars, Altair low in the west, Fomalhaut low in the south south west, Aldebaran low in the East, and Capella high in the north east.
  • Also aligned scope on Venus, which was low in the south west at about 1835hrs.  While setting up to image Venus, clouds covered that part of the sky.
  • Located and imaged Comet C/2017 T2 for two hours.  Comet is still too faint to see without the aid of a medium sized telescope.  Images showed significant movement of the comet, north eastward, towards the w of Cassiopeia. Comet's placement in the sky is about halfway up in the north east, in northern Perseus, after first dark.  As the evening goes on, it quickly moves high overhead, making it difficult to image.
15x120 second, ISO 1600, f/6.25, cropped. Total of 35 minutes of processed imaging. Shows comet moving north over two hours of imaging.
  • Imaged the comet from about 7-9pm.  At 715pm a satellite crossed through the image field of view.

This is the only comet image that hasn't been cropped.
  • Wanted to show how the comet moved over two hours in a different way.  Tried making a video of the 15x 120 second images, but it didn't turn out well.
  •  Processed these three images that were taken at 7pm, 8pm and 9pm, also to show how far it moved over the 2 hour period.  Notice how it moves away from the star it almost covers at 7pm.

  • There has been much chatter on the internet, by amateur and professional astronomers and even the main stream media, about the dimming of Orion's alpha star, Betelgeuse.  It is noticeable to the unaided eye, and it was reported, officially, in October of this year.
  • In Robert Burnham, Jr.'s Burnham's Celestial Handbook, he describes Betelgeuse's variability like this, "The main period appears to be about 5.7 years, but there are shorter superimposed periods which vary between 150 and 300 days.  When at maximum the star sometimes rises to  magnitude 0.4 when it appears not greatly inferior to Rigel;  in 1839 and again in 1852 it was thought by some observers to be nearly the equal of Capella.  Observations by the AAVSO indicate that Betelgeuse probably reached magnitude 0.2 in 1933 and again in 1942."  From this and other observations regarding Betelgeuse, it's magnitude is a confusing subject.
  • Took two twenty second images of Orion.  The second image of Orion was purposely out of focus to show how bright Betelgeuse is compared to the other stars in it's constellation.
Betelgeuse's magnitude has dimmed from a normal of about 0.4 to 1.12.  The lowest measurement of magnitude 1.12 was taken by scientists on December 7, 2019 and is the lowest it's been in 25 years of continuous observing.

Out of focus to more easily view the magnitude difference of Orion's brighter stars.  Sirius in the lower left is in another constellation and is the brightest star that can be seen from New Brunswick, Canada.
  • Many satellites were seen, with one imaged, and one shooting star, passing under the field of view of camera, as imaging.  It was a slow mover coming from the direction of Polaris heading toward Orion.

COMET C/2017 T2 PANSTARRS

Location:  Front Porch, Little Lepreau, NB, Canada

Date Time:  December 20, 2019 1800-2130hrs

Weather:  Cool, at time breezy, winds dying off after 2100hrs, -5C.  Partly cloudy until clouds covered sky at 1900hrs till about 2100hrs.

Equipment:  Canon Rebel T3 attached to 80mm ED/APO at prime focus.  Eyepieces:  12mm, 19mm and 32mm.  Images processed on Photoshop.

Attendance:  David McCashion

Objective:  To image and view comet C/2017 Panstarrs T2 in Perseus.

Report:
  • Sky darkened by 1800hrs, aligned scope on 4 stars and Venus.
  • Located the comet approximately halfway between Capella and Perseus's brightest star, Mirfak(Arabian for elbow).  Took ten images of about 80 seconds each, totaling approx. 14 minutes of exposure time to create a stacked image.  Also took one single shot, highly exposed to show more of the comet.  Comet was too faint to see through any of my eyepieces when I searched visually.
  • The stacked image shows a 14 minute path of the comet nucleus in relation to the background stars.  This comet is a slow mover compared with other comets I've imagined.  Actually, it's the slowest.
Stacked image shows a movement of the comet nucleus over 14 minutes.  10x80second, ISO 800.  Not cropped.

Single shot, over-exposed to better show the nucleus, coma and tail.  ISO 1600, 1x80 second.  Not cropped.


  • Seen several satellites, but no shooting stars.

COMET SEARCH

Location:  Front porch, Little Lepreau, NB, Canada

Date Time:  December 18, 2019 1700-midnight.

Weather:  Very cool, no wind, -8C to -10C, no dew, mostly cloudy, with an approximately 30 minutes of clear sky from 2200 to 2230hrs , to mostly cloudy.

Attendance:  David McCashion

Equipment:  Canadian telescopes 80ED/APO on a tracking mount with Canon Rebel t3 attached at prime focus.  Images processed with Photoshop.

Objective:  To search for comet C/2017 T2 Panstarrs which was reported to be in the constellation Perseus by heavens-above.com.

Report:
  • Sky clouded over shortly after dark, around 1700hrs, and didn't clear until around 2200hrs.  
  • Aligned scope on four stars, and then began a search in the area to the north of  Perseus brightest stars, where the comet was thought to be.  At this time, around 2220hrs, Perseus was almost straight up, slightly to the north, which made it exceedingly difficult to image.
  • Imaged five different field of views in the area, where I thought comet should be, but during the last two, clouds started to move in.  Last image, which turned out terribly, I think captured the comet, but not sure.  Was clouded out for till midnight, when I decided to pack it in.  Here is the image that I think has the comet in it.  In the upper right.


Possibly captured comet in upper right of image.  Single shot, 47 second, ISO 6400, imaged at 2234hrs, as clouds were moving in to cover sky.



  •  In the second image, captured open star cluster NGC  1528.  According to Burnham's Celestial Handbook, by Robert Burnham, Jr. this open cluster contains "about 80 stars mags 8...1 degree NNW from b1 Persei".
NGC 1528 next to b1 Persei taken at 2225hrs. Single shot, raw  ISO 6400, 66 second, and focal length of 50mm.


  •  No satellites, one bright shooting star, high, to the south west of Orion, heading NNE.

PURPLE SKY AFTER SUNSET

Location:  Front yard, from driveway, Little Lepreau, NB, Canada.

Date Time:  December 7, 2019 1645-1655hrs.

Weather:  Mostly clear, light breeze, -4C, sky seemed purplish around the western and eastern horizons.

Attendance:  David McCashion

Equipment:  Canon Rebel t3 on tripod with 18-55mm lens.  Image processed on PhotoShop.

Objective:  To capture the purplish hue to the twilight sky.

Report:

Noticed a purplish hue to the evening sky and made an attempt to image it. 

On Spaceweather.com recently seen images from other places around the world that show a  purplish twilight sky.  Apparently it's related to volcanic activity.

I'm not sure which volcano is responsible for the purple, but there is volcanic activity being reported in New Zealand. 

1/200 second, f/5.6, ISO 100, focal length 55mm.  Only processed to add text, besides that image is raw.
