A big thanks to PhotoGav who posted some simple to follow instructions on how to use the stand-a-lone software earlier in his M27 thread.
I'll post again, but add that any file names must NOT include spaces. You can instead use a '_'.
If (as I do do), you embed your RGB files with a colour profile upon saving, that appears to be fine.
How to get the standalone Starnet version to work on the Mac
1. Download the latest version of Starnet for Mac OS from here:
2. Unzip the folder and place it on your Desktop
3. Save the image that you want to make starless as a 16 bit mono or RGB .tif file
*****DO NOT use spaces in file name, instead use _
4. Place the file in the Starnet folder on your desktop
5. Open Terminal and navigate to the Starnet folder, copy this command:
cd ~/Desktop/StarNet_MacOS - into Terminal and hitting Enter
6. Open in Text Editor either the file:
depending on whether you are working with a mono or RGB file and edit the filenames in there to be the filename of the file that you want to make starless
Save the txt file above in part 6, then....
7. Drag either 'run_mono_starnet.sh' or 'run_rgb_starnet.sh' onto the Terminal window and you should see the path of the the file appear
8. Make sure that Terminal is the uppermost window and hit enter - Program will run (this can take a while!)
9. When it's finished doing its magic, go to the Starnet folder, open up the _s version of your file and be amazed at the results!
I am (amazed), thanks again Gav for posting!
Some examples from playing around late this afternoon... the starless colour and mono images straight out of StarNet, no extra processing.
I still prefer my images with an embedded star field, but this should be great fun and be rather useful whilst processing...
The Ha data
I have guiding problem with the following guider setup: 9x50 finder + ZWO ASI 120mm mini + PHD2.
The imaging scope is a 6' newtonian + canon dslr on a HEQ5, driven by a laptop via diy EQDIR cable.
When the mount is set up and running correctly, polar aligned and all... I connect the guider camera
and mount with phd2. All nice and easy, I run a calibration, then it starts to guide. All seems ok.
Then I am starting to take pictures. The first seems OK, then the second have the star trails...
I check phd2 and there is a message: the camera (ASI) did not take a picture for "xy" seconds so it is disconnected.
Grrr.... I reconnect try to set up a longer period for "xy" in the settings as mentioned in the message.
And all the same again and again. Whatever I add for connection timeout for the camera, it just reaches that
and disconnect the camera.
PHD + philips toucam has worked for me flowlessly. I changed to PHD2 because I gave myself a birthday present,
the little ZWO camera. (and PHD did not recognize it)
Do you have any idea what can be the problem? I will contact PHD2 help also, but maybe somebody had already
the same problem and figured out how to overcome. I am almost sure I make some dumb mistake in the PHD2
software settings, however I tried to change only what was needed.
Ok, so this is a really annoying bug / problem that I have with my setup:
From time to time, in non regular intervals the image my guiding cam (ZWO ASI120) send seems to get flipped / mirrored or looks like it's from a completely different patch of sky.
When I'm paying attention to the guide images I can clearly see that the image seems to be flipped in some way.
It only happens for 1 frame PHD send a warning ( No star found / Star lost Mass changed) and after that everything is fine again. My gear is all connected to a single USB3 Hub which then runs via powered USB3 cable to my Pc.
I'm not binning and have the noise reduction off (though PHD might got hickups while processing) but it still happens. Sometimes there are minutes between two events sometimes it happens 5 times in a row.
It also seems like it's only happening during guiding, I haven't seen it happen during calibration yet...
I'm completely clueless what's happening or how to get rid of it, any help / idea is greatly appreciated.
