The Moon and Jupiter

The moon and Jupiter on the morning of January 28, 2016 from the Seymour High School parking lot. The image is a composite of two images. A long exposure (3 s) to get Jupiter, its moon Ganymede, and some stars and a short (1/500 s) exposure to get detail on the Moon. The images were then combined in Photoshop.

M35 and M36 the other night! (1-7-16)

Two more Messier objects off the list. M35 and M36 are both open clusters located near each other. The shots are OK but not great. Unfortunately, the autoguider was not guiding properly so I only took ~15 minute exposures. Because the images show star streaks when magnified, I used very little cropping. I have not had this problem before, the only thing I can think of is that the polar alignment was off or my alignment was so far off the guider could not overcome it.

M35 is located in Gemini approximately 2800 light-years (ly) from Earth and 22 ly across. Located in the lower right side of this image is NGC 2158 which is another open cluster similar to M35 but appears much fainter as it is 5-times more distant. M36 is located in Auriga approximately 4100 ly from Earth and 14 ly across. Also located in the lower right side of this image is a small nebula which I have not able to identify.

Finding the right Periodic Table

One of the challenges of teaching chemistry is finding the right periodic table to use.  There are a plethora of different periodic tables out there, but they have way too much information on them for beginning chemistry students to use or even understand.  Some of them are worse than trying to find which way to go after exiting off the George Washington Bridge - there are too many billboards!  On the other hand, you can get simple tables but they don't have enough information to be useful.  Since the International Union of Pure and Applied Chemistry (IUPAC), chemistry's version of  the IOC, just gave their blessing to the last four elements discovered, or more appropriately, produced in a particle accelerator within the past decade, I figured it was a good time to update the periodic table I made several years ago.  I was unable to find one that worked for what I was teaching so I used Word to make my own Periodic Table (GOOD THING I LIKE REALLY TEDIOUS JOBS).

The updated Periodic Table includes: 1) recognizing the elements 113, 115, 117, and 118 are real; 2) names for element 114, now Flerovium (Fl), and element 116, now Livermorium (Lv); and updating the atomic masses to one or two decimal places (although not as accurate, it is much simpler).

NOTE: Because you wanted to know what they are named after...
Flerovium is named after Flerov Laboratory of Nuclear Reactions, Russia, where the element was discovered in 1998.

Livermorium is named after the Lawrence Livermore National Laboratory, USA, where the element was discovered in 2000.

Braved the Cold to Image Comet Catalina

Braved the cold to image this Comet (Comet Catalina C/2013 US10). It is a 20 km diameter piece of rock and ice originating from the Oort Cloud that has been traveling towards sun for approximately 1 million years. It is now moving away from the sun and will probably never return (telescopes.com). The green color comes from cyanogen (CN: a poisonous gas) and diatomic carbon (C2). I love astronomy and astrophotography but I can't stand being out when it is below 40 degrees and breezy. At 4:00 am on Jan 2nd in Monroe CT, it was 26 degrees with a wind chill factor of 19 degrees. I have never imaged a comet before and probably won't again unless it comes when it's warmer out. There are few different methods for doing this: 1) single frame, 2) autoguiding on a background star, 3) autoguiding on the comet, 4) autoguiding on a background star and single point stacking on the comet. For a good summary of these methods visit Astrokev.com, Karlsson's Homepage, Soggy Astronomer, Bernhard Hubl Astrophotography.

Method three (3) is the best and I tried to do this but had a couple of issues. I have always used PHD autoguiding program but figured since PHD2 had a comet setting, I would try it. Unfortunately, the program never calibrated, so I wasted a half hour getting frustrated with that (in the cold). I connected it to PHD and had no problems. The problem was that the autoguider could not see the comet so I could not lock onto it. My guide scope (Orion ST80) is connected to the imaging scope with mounting rings so there is no moving it around, it has some pluses and minuses - this being a minus. I do have guide rings and if I had more time and it was warmer out might have changed it out. Oh well, I was relegated to the second best method, that being method four (4).

Note: It is possible to merge the best comet image from method four with the background stars from method two using photoshop. I tried this but I was unable to do this do to my lack experience with photoshop. Image 2 was using Deep Sky Stacker's Comet stacking function with star background calibration. Image 3 was using Deep Sky Stacker's Comet stacking function without the star background calibration. Image 4 was Deep Sky Stacker's Comet stacking function with additional unguided comet sub exposures.

M103 vs. The Double Cluster

Got another Messier Object on my quest of imaging all 110 objects (Messier Objects with an ED) with my Orion ED80. In addition stopped by the Double Cluster for a peak. M103 is located very close to Ruchbah, one of the five bright stars in the constellation Cassiopeia.

As a side note, I recently purchased the QHY-5L-II-M autoguider/planetary camera for autoguiding. So far I love this autoguider, it focuses really well on objects and quickly calibrates using PHD, even when moving on to different objects. See my recent post on the Autoguider at http://kurt-zeppetello.blogspot.com/2015/11/new-images-for-messier-quest.html.

Comet Catalina (C/2013 US10)

This was my first attempt to get an image of the comet C/2013 US10 (Catalina).  The images are from my work parking lot (Seymour High School) in southern Connecticut.  I don't consider these images to be that good, as I was hoping for better.  However, when I first looked at them I did not think I got anything, Southern CT isn't known for dark sky's and this comet isn't living up to early expectations.  It was only when I playing around with Photoshop and Picasa3 that I was able to resolve the comet.  I plan on getting respectable images with my telescope when it passes within 1 degree of Arcturus on January 1st or January 16 when it is close to the handle of the Big Dipper.

The comet became visible to viewers in the Northern Hemisphere in mid-November and is now heading away from the sun on its way back to the Oort Cloud from which its hence.  According to Kelly Beatty (Sky and Telescope) it will be closest to Earth on January 12 at a distance of 0.72 astronomical units (108 million km).

Toyota RAV4 Side Mirror Wiring

I replaced my passenger side mirror on my 2009 Toyota RAV4 with the Kool-Vue replacement model (power, heated, turn signal).  There are some very good tutorials on how to do this.  I used one on YouTube by Mike Wilza: link.  He gives a quick and easy to follow demonstration on what to do.  However, my problem arose when the new wiring clip did not match the original clip.  After doing some research particularly on RAV4World.com, I discovered there were two RAV4 manufacturing plants, one in Japan and the other in Canada.  The mirror I was sent was the one from Japan while my RAV4 was from Canada. 

So rather than send it back as some suggested, I replaced the clip on the new mirror so it would work. Fortunately others have done this, unfortunately not with the heated model so I had to guess.  The following are the wiring connections I used:

Toyota:               Kool-Vue
green:                  red
blue:                    brown
yellow:                purple
white:                  white
pink:                   pink
black:                  black
black (white dot): black (writing)

It works well, however, one of the connections is reversed. When I want the mirror to point away from me, it points towards me and visa versa. The up-down works normal as does the turn signal.

I like this tiny anomaly so I am not taking anything apart again...

Attached is a photo of the wiring of the new mirror to the original clip.
