The President’s Corner
Happy New Year! As we begin another
trip around the Sun we’re doing so in the
company of El Nino. This means increased
wet weather and clouds. I think it’s going to
be a “more cloudy than usual” winter for us
here in the desert but hopefully most of us
can take advantage of what clear nights we
do get and enjoy some observing time. This
interesting chart shows the overall scope of
the warming in the Pacific.

We have two new officers elected this
year, Kevin Kozel and Steve Dodder. Kevin
moved to the Secretary position from
Properties Director and Steve took his place
in care of the club’s common equipment.
Thank you both for stepping up to help SAC.
To kick off this year’s speakers, I invite
you to come to the meeting on the 22 nd at
GCU and listen to Phil Massey from Lowell
Observatory talk about, “Steller evolution in
local galaxy groups.” Also, on January 23 rd,
the Vatican Observatory Foundation will host
a local lecture on “Water in the Universe.”
See the announcement section for details.
Let’s all hope we have a great 2016
under the stars.

Hopefully, things will have dried out by
the time our annual Messier Marathon rolls
around in March. That’s just one of the
events I hope club members can attend this
year. Speaking of events, you should know
that next year, SAC will turn 40 years old. I
do not think it would be too early to begin
thinking about what type of celebration the
club would like to have to commemorate this
occasion. Don’t be afraid to bring forth your
ideas.

Schedule of Events 2016
Hi Folks,
SAC General Meetings
I hope you like the new look of the header on
page one of the newsletter. As you know, another
year of Saguaro Skies, another header, this year
featuring a star atlas version of Scorpius setting in
the west, as portrayed in the SAC logo.
Best Of the NGC features this month, NGC
2024, The Flame or Tank Track Nebula in Orion.
Several imagers sent in images, thanks!
SUCH-A-DEAL has four ads, need a telescope? I
know several folks who are selling some.
Bits & Pisces has photos of the SAC Holiday
Party taken by Susan Trask. Also, see SAC History
from the past.
SAC Imaging has a story about imaging M33 by
SAC imager David Dillmore. He describes how
adding flat files to the image really cleans them up.
On the second page, Tom Polakis goes on another
of his marathons in astronomy, this time imaging
47 comets in one night! One wonders about his
crazy activities sometimes. Hey, it's ok Tom!

Best Of The NGC:
NGC 2024, The Flame or Tank Track Nebula in Orion
By SAC Imagers, Observers & Sketchers, Compiled by Rick Rotramel
SAC Observer: Steve Coe
SAC Observer: Rick Rotramel
TV 102; Antennas, S=6 T=7, 14mm eyepiece
S+T=6, faint, pretty large, round and shows the dark
"Tank Tracks" feature that cut this nebula almost in
half. All of this easier to see if the bright star Zeta ORI
is moved out of the field of view.
6" f8; Antennas, S+T=7, 14mm, pretty bright, very
large, irregular figure, dark lane easy, averted vision
makes it much easier.
10" f5.1; Flatiron, S+T=6, 22mm Panoptic, with
low power and no filter, but the UHC does help. Much
better contrast with 8.8mm EP, you can get Zeta out of
the FOV. The UHC does NOT help at higher power. The
branches of the dark lanes are seen at higher power
and averted vision makes a real difference, it helps the
light/dark contrast.
13" f5.6; Sentinel, S=6, T=8, 135X with a UHC
filter helps the contrast a lot and so does getting Zeta
out of the field. Because of the large, parallel dark
lanes, Arizona astronomers have taken to calling NGC
2024 the "Tank Track" Nebula.
16" f4.5; Antennas, S=7, T=7, 14mm eyepiece
pretty bright, large, irregular figure, it is easy to see
once Zeta ORI is moved out of the field of view. There
are 6 stars involved and the dark "Tank Tracks" feature
is easy with direct vision. Averted vision makes it
larger.
17.5" f4.5; Sentinel, S+T=7, 200X, Bright, large,
irregular emission nebula near Zeta Ori. It is easy in
any telescope I have ever used under dark skies, the
17.5 incher brings out much detail in the region at
200X. There are thin dark branches that wind out from
the two main dark lanes through the nebula. The UHC
filter helps the contrast somewhat, but moving the
bright star out of the field helps more.
16" f4.4 Newtonian; Pretty Large, pretty Bright,
dark lanes traverse this nebula. Pretty!

Spaceflight Trivia Answer
Huygens
Mission type
Lander
Launch date:
15-Oct-1997 08:43 UT (From Earth)
Operator:
ESA/ASI
Launch date
December 25, 2004 (From Cassini)
Launch vehicle
Cassini orbiter
Mission end:
Huygens Probe - 14 January 2005
Cassini Orbiter
Launch vehicle:
Titan-IVB/Centaur
Mission phase:
Huygens - Mission completed 14 January 2005
Cassini - Solstice Mission (ongoing)
Orbit:
To reach Saturn, Cassini-Huygens used a series of gravity-assist
manoeuvres, with swing-bys from Venus (2x), Earth and Jupiter. On 1 July 2004 the
spacecraft entered into orbit around Saturn after being captured by the planet's
gravity.
Achievements:
The Huygens probe has successfully landed on Saturn's
largest moon Titan. At around 11:30 UTC 14 January 2005 the probe touched down
on the surface of this distant world. This event makes it the only landing to take
place in the outer Solar System and the furthest from Earth.

Imaging M33, by David Dillmore
Attached are two photographs of
M33, the Triangulum Galaxy. The
photos are in-fact the same
photograph, one is processed
without Flat Files (Version A) and
with Flat Files (Version B). The
comparison shows the effect of
adding Flat Files to processing. I
cropped Version A but not B.
The photographs were taken
November 11, 2015 on and about
10:30 pm using my Celestron 8inch Newtonian with the AVX
mount. My camera was a Nikon
D3300 DSLR. I used a 2" diameter
Multi-Purpose Coma Corrector and
a Sky Glow filter. I made my own
adaptor to fit the 2" filters on my
camera to the telescope
(Celestron`s camera attachment
does not provide for 2" diameter
filters).
I used 2 alignment stars and 2
calibration stars (forgot which
ones). The telescope was
unguided. The ISO was 12800, I
shot 30 exposures but could use
only 22 exposures, each 20
seconds for a total exposure
time of 7 minutes 20 seconds.
There were 12 bias frames of
1/4000 second, 12 dark frames
at ISO 12800 for 20 seconds
each, and revision B received 12
Flat Frames ISO 12800 for 6
seconds each.
I complained to Steve Dodder
about the vignetting and
background glow I was getting,
he recommended adding the
flats files and to make them by
simply pointing the telescope
straight up in the late afternoon
on a cloudless day and start
shooting. The flat files worked.
My next step is to incorporate a
guide scope and camera. I want
to reduce my ISO to reduce
graininess and increase
exposure time.
The pictures were processed
using Deep Sky Stacker and
Corel Paint Shop Pro.
Respectfully,
David Dillmore

Saguaro Astronomy Club
Saguaro Astronomy Club (SAC), Phoenix,
Arizona, was formed in 1977 to promote
fellowship and the exchange of scientific
information among its members-amateur
astronomers. SAC meets monthly for both
general meetings and star parties, and
regularly conducts and supports public
programs on astronomy. Membership is
open to anyone with these interests.
Saguaro Skies is posted as a pdf file
monthly on the SAC website,
www.saguaroastro.org/content/SACNEWS/newsindex.htm
for browsing or downloading for SAC
members and friends of SAC. A email
announcement of the monthly newsletter
release is included with membership.
Parking: Turn into the campus from Camelback Road at
33rd Ave. and drive straight and stop at the guard
station. Tell the guard you are attending the astronomy
club meeting. Then, turn left past the guard and park.
Direct all membership inquiries to the
SAC Treasurer by using the membership
form found in this newsletter. For editorial
and SUCH-A-DEAL advertising inquiries,
