Smith Mountain State Park, Virginia

Another exposure of Barnard's Star, just to check
if I could notice any small movements.

I compared it with my picture from May.

I think I see a variable star

RA 18h 05m 25.8s
DEC +05:13:15

J2000: 271.3575 5.22083333


Also, I think I may have gotten some movement out of
Barnard's Star. It might not be movement, but if it is,
then it's a very small amount of it.

A second exposure confirms that my recent
finding was not a camera error, but a variable star.

ISO 6400 1s f/5.6
50 light / 10 dark
Bortle 8

All of my pictures of this star. You should be
able to see the star changing in brightness.

closer.gif:
In case the first one is too small, this
compares two shots, showing that the star
clearly dimmed in the later one.

I scoured tons of star catalogs, and I could only find one
source documenting this star:
http://astro.corlan.net/stars/OPH/SV-OPH.html

It's right beside Barnard's star, a common target.
Surely this star should be more popular...

While taking a picture of Barnard's Star, I noticed this.
These were taken 50 days apart, and the star is not there in the
newer picture.

ISO 6400 1s f/5.7
50 light frames, 20 dark frames
Stacked in DSS

Explanations sorted by likelihood:
- crud on camera sensor
- processing glitch
- Variable star, or dust
- It just disappeared or something
- Aliens???

Barnard's Star

> Barnard's Star is a red dwarf about six light-years away from Earth in the constellation of Ophiuchus.
It is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system,
and the closest star in the northern celestial hemisphere. Its stellar mass is about 14% of the Sun's.
Despite its proximity, the star has a dim apparent magnitude of +9.5 and is invisible to the unaided eye;
it is much brighter in the infrared than in visible light.

Canon 1300D
ISO 6400
1s
f/5.6
50 Light frames
20 Dark frames
Stacked in deep sky stacker

I didn't use a star tracker, only constellations and public data.
This was very difficult in a Bortle 8 city with a target near the horizon.

The "Christmas Star"
Saturn and Jupiter align. This happens once every ~20 years, but
this happens to be the closest since the 1700s.

The GIF was made from 8 frames, ISO 6400 4s f/5.6, manually
stacked with GIMP

The JPG is just a compressed image from my camera, edited slightly
with GIMP

ISO 3200 f10 1/800s Manually tracked, 300mm Canon DSLR
I took ~40 pictures of the ISS, removed the bad ones, and ended up with ~30.
I manually aligned them in GIMP, and exported to GIF.

The Ring Nebula is tiny. A real telescope would be needed in order to get
details. But you can see, it is a blue thing, with a hole in it.

Very good visibility. I was near a big lake, and in one picture you should be able to see
the Milky Way reflection in the background. From the pictures I took that night, I am making
a map of the milky way.
