M35

Post by NDB » Mon Jan 13, 2014 9:38 pm

Thats' my first basic deep-sky image with ASI120MM. I followed the tips from mitovka and I screwed a vintage 135mm pentacon photolens (M42 thread), with a manual filter wheel. Due to the poor quality of this optics, the iris was closed to 1:5.6 and I used the green image as luminance, the colors comes from classic RGB images. 50x4,5s for each color. The "luminance" is 180 x 20 seconds. The darks are automatically subtracted with FireCapture (brilliant software!).
Unfortunately I don't have any light pollution rejection filter, and the main signal comes from the city lights...
I'm sure this camera can provide far better images.
Nicolas.

Thanks, Astro47.
FireCapture is slightly hard to understand, especially the parameters associated to the "filter" selection and to the "profiles". But it's quick, perfectly suited to the ASI120MM performances and possibilities, and I LOVE the real-time dark subtraction. In adition, it can stack frames on the run to see dim objects. Time-lapse became very easy, too.
And the file names compliant with WinJupOs is a brilliant idea (for planets of course).
It lacks some functions like QGVideo (from QHYCCD): a strong contrast enhancement to help focusing on planets/moon (FC's "gamma" is not as good), and real-time colorization for H-Alpha imaging with audience. But one can manage these lacks.
It has been told that FC 1) requires JAVA and 2) is slow. That's 1) doubtable (perhaps a hidden run-time?), and 2) false. If you stop the resident softwares, of course.
In a few words, FC requires several nights of practice. But it deserves it.
Nicolas.

Thanks Nicholas for the info on Fire Capture, sounds a bit complicated to me but I'm sure it isn't too bad once you start playing with it. I have used the basic soft ware that comes with the ASI034MC which I have got, but Sharpcap is much better. I am now using this with Registax and a bit of Photoshop. Will try Fire Capture in the future once I get a bit more proficient.
