Feb 4, 2013: second attempt at H-alpha

[michael.h.f.wilkinson]

Apart from an attempt at white light, I had a go at H-alpha with the ASI130MM and the Lunt LS35THa. Conditions were not ideal, but I managed to snap some frames, and I found time to stack them this evening. Not perfect, but quite nice for imperfect conditions and a beginner at the helm. 480 frames stacked with AS!2, wavelets in Registax, gradient removed with ImageJ, and curves and combination of prominence and surface image in Registax. Still struggling with some camera artefacts

Thanks, I am still working on better ways of combining the prominence images with the surface detail image.

Hi Michael. those look great - what is AS!2 though? I tried googling it but couldn't find anything

AS!2 = AutoStakkert! 2

great start

did you captured the hole disc with a single frame of the camera on the lunt or you used some reducer or mosaic?

Number 1 is my fave

Nice work Michael. I like the wispy proms and the surface detail is looking good.

Outstanding work. Thank you for sharing your art work

Thanks! The ASI130MM has a 1/2" video-size chip (same as the QHY5) so the entire disk fits on the chip in one go (the little LS35 has only 400mm focal length).

Cheers! It has the advantage of being a single shot, rather than being a composite. I have to work on my technique

Thanks for all the comments. I am now considering how to mod the LS35 into something bigger.
