To all my loyal readers, do you find it frustrating when you visit here and found no new article? You can subscribe the RSS feed and use your RSS reader to keep it up.
Anyway, I’ve decided to post a minimum of every 2 days. I’ll start to write the article from 9.00PM. You shall expect it after 10.00PM 
Oh yeah, kudos to the author of Imager Manager and WP lightbox for the cool visual view of any images clicked in AstronomyNotes.net Why not you try to click on any image (thumbnail) to try the feature? It is really cool, I must say.
By the way, stay tune for tonight astrophotography session! Seems like the cloud is clearing but I can’t ensure it.
The Southern Delta Aquarid meteor shower peaks on July 28th. Go outside before dawn on Friday morning, look south, and you could see a meteor every five minutes or so.
No one knows where these meteors come from. They could be remains of a long-dead comet or debris from an asteroid-asteroid collision. Curious fact: There is a debris stream nearly parallel to this one. Earth will pass through it on August 8th, producing the Northern Delta Aquarid meteor shower. It’s a mystery, too.
I haven’t seen a meteor this year. I’ve missed 3 meteor shower events, I hope I have the luck to take a look on it again.
On the bright lunar morning, the sky is always dark due to the absent of atmosphere which is as black as midnight. Isn’t it an astronomer’s paradise? No. Not a single star was visible. The glaring, sunlit ground ruined the man’s night vision. Only Earth itself is bright enough to be seen, luminous blue and white, hanging overhead.
Based on this conclusion, we know that a dark sky is not enough. A dark environment is needed too. However, we can’t really find a dark site in urban areas due to the high growing light pollution.
Yesterday night was cloudy, I could only see Rigel Kentarius , i.e. only a little part of southern sky is clear. I’ll try again tonight. Jupiter will be my target again for the astrophotography session.
By the way, I am going to implement a translator to benefit my chinese readers.
As I promised, I took this photo together with my precious Meade 8″ LX90. So far, it is still performing like the new made. I am just worrying about the above average humidity of my room which will cause damage to the primary mirror of my telescope.
I was standing on the best position for stargazing as the tree helps to block the stupid road light and holding my road warrior, Dell Inspiron 640M. I am sure that you know where is the LX90. 
By the way, sorry about that I didn’t have a comb before I took this photo.

Below is the summary of the press release from NASA.
The Space Shuttle Discovery and its crew are home after a 13-day, 5.3 million-mile journey in space. The mission, STS-121, succeeded in testing shuttle safety improvements, repairing a rail car on the International Space Station and producing never-before-seen, high-resolution images of the shuttle during and after its July 4th launch. This mission has elapsed 12 days 18 hours 37 minutes and 54 seconds.
I have figured out a new format for every photo-op articles, let’s take a look of it!
Telescope: Meade 8″ LX90 w/UHTC
Imager: Meade Lunar Planetary Imager
Software: Meade Autostar Suite
Filter applied: None
I am quite satisfied the result of this image. It’s the least stacked photo with the most gorgeous details. I intended to turn on the screen by touching the touchpad but I forgot that the cursor was on the stop button. It could be better.
Discovery is planned to be landed on Kennedy Space Center. However, the leaking may affect the plan.
The NASA engineers are seriously monitoring the leak in the pipeline of an auxiliary power unit that controls hydraulic steering and braking maneuvers. It’s now leaking at a rate of 6 drops per hour. It’s either harmless nitrogen or flammable hydrazine fuel. Nevertheless, the current rate is still 100,000 times slower than what would cause a fire.
I am so happy to announced that my blog is currently ranked page rank 4 as known as pr4! 
This is really an encouragement to me. I am sure to write more informative contents in the future.
