don4l, 

  In ASTAP version 0.9.211 is the font for HyperLeda annotation fixed at 8. I hope you like it. Feedback is welcome.

kirkster501,

  Yes and each has galaxy has typical 100.000 million stars.

At first, the labels were far too large, and overlapped each other.  However, if I zoom in before annotating, it uses a smaller font.  I mention this in case other people have the same issue.

 

 

 

Yes you remind me , I have put that in the hint and manual.  The font is depending on the zoom factor.  Maybe it is better for HyperLeda annotation to make fontsize always small.

I did the same for M13. Here a part of the image:

This image was made two days ago when the M5 global cluster was near the meridian. The second image shows by annotation how many galaxies are hidden within the image. Most galaxies are recognisable. It is quite astounding how much is visible. Unfortunately I can post only compressed JPEG images, but the full resolution link is already  better. Annotation by the latest version of the ASTAP program using the HyperLeda database.

Once your started programming in a language/integrated development environment (IDE) it is very difficult to switch and you could be locked to Windows or an other operating system or facing fading compiler support.  I assume most start coding in an environment they like or are used to and don't consider multi platform support until much later.

The development of NINA goes very fast and programmers seems to be permanent online for support so this promises a great future. (for Windows users only )

For the ASI1600, in most cases  you better stick to unity gain=139, offset 21.  Especially if you imaging deepsky and want to use the full 12 bit range. All other settings give less range. Your light , flats and darks should be made with the same settings.

I would suggest to start with installing Linux in a virtual machine.  I use the free VMware workstation player for that. Install it under Win10, and download a Linux ISO and install it in the player. Then if you install the included VMware tools you can also copy and paste between Windows and Linux. The virtual machine itself  you can copy to the computer in your obervatory and run it there again under Win10 or what you have or give to a friend.

By this you can try different Linux flavors and just delete copy or keep as as many as you wish or run even in parallel. (typical disksize  required 10 gbytes, 6 gbytes minimum)  A computer with 4 gbyte ram or even 2 gbytes will work fine with Win10 and a virtual machine.

For Windows users maybe, a Linux flavor with LXDE  like Lubuntu as interface will be actractive and easier to use.

You could also download and try  "Astronomy Linux ", an Ubuntu with already many astronomy programs installed

The Linux in the virtual machine will be able to control your telescope and have access to internet.  It is  easier to install and experiment then dual boot and removal is easy if you don't like it.

This is an interesting development.  I think in the introduction or documentation you should describe a little more about the pre-conditions and installation.  As far I understand you need either:

1) A Linux system with a local astrometry.net installed.

2) Win10 64 bit Creators edition, Linux sub system installed. E.g. you could use my guideline as a start:

http://www.hnsky.org/linux_subsyst.htm

3) Windows system with Cygwin version of Astrometry.net v0.38  ??

Programs should be able to execute astrometry.net locally but this will help for the programs which only have a web interface to astrometry.net.

Here is what I got so far:

Stellarium
Cartes du Ciel
Iris
PixInsight
Virtual Moon Atlas

 

Good the read that there is interest in Linux. I just release the first Linux version of the Hallo Northern sky planetarium program. See thread

Linux is also new for me. It is compiled for AMD64 and the executable in this latest version is called "hnsky". Just unzip the files somewhere at your home drive. In future, I will compile more versions then just AMD64. If your are in need for a 32 bit version, send me an email or respond to above thread and I will include it.

Any feedback is most welcome.
