NGC 4038 / NGC 4039 - The Antennea Galaxies

These two spiral galaxies, drawn together by gravity, started to interact a few hundred million years ago. The Antennae Galaxies are the nearest and youngest examples of a pair of colliding galaxies.

It has been a while since I posted an update on the Comet app download stats. So, here are the latest stats on the Comet iPhone app. So far a total of 548 downloads and still a 5 star rating.

USA: 285
France: 37
UK: 35
Australia: 28
Canada: 27
Italy: 20
Spain: 15
Germany: 13
Belgium: 8
Mexico: 8
Others: 72

The current version is 1.1.2 which added a couple of improvements to the filtering of the comet list. It also added a "Night Mode" for visual observing to help preserve night vision. I have so many ideas for this app and I hope to implement them soon. I just need to find time to work on it between my day job and family time.

Here are the latest stats on the Comet iPhone app. So far a total of 323 downloads and a 5 star rating.

USA: 166
UK: 25
Australia: 22
France: 17
Canada: 15
Italy: 15
Spain: 9
Germany: 6
Belgium: 5
Ireland: 3
Others: 40

Version 1.1.1 has just been uploaded to Apple. It will resolve the issue of the RA lower limit being greater than the RA Upper Limit. Hopefully that will be approved soon and be ready for update.

Here are the latest stats on the Comet iPhone app. So far a total of 231 downloads.

USA: 108
UK: 22
Australia: 18
France: 14
Canada: 12
Italy: 10

Before i shut down for the night, I also took a quick shot of the Veil Nebula. This is a single 5 minute exposure.

Thursday I uploaded an update to the Comet iPhone app to Apple. We are simply waiting on them to approve and release it to the iTunes store at this point. In this new version are features that were requested (and honestly needed). 

The new features include:

• The ability to sort the comets by Name, RA, Declination, and more.
• Sort in Ascending or Descending order
• Filter the list based on upper and lower RA limits, upper and lower Declination limits, and a magnitude limit.
• The ability to manually enter GPS coordinates rather than use the coordinates the iPhone determines.
• All of these settings are saved between sessions. Set your limits, sorting, and GPS coordinates once and they will remain each time you enter the app.

Hopefully Apple will approve this update shortly and everyone can enjoy these new features. 

Again, if you think the app is in need of other features or have any other suggestions at all, please drop me an email. I will do my best to make sure that valuable additions to the program make it in there.

If you have downloaded the app and find it useful, please take a moment in iTunes to rate the app.
