Reprocess and some more images from last night

[michael.h.f.wilkinson]

Here is a collection of images from last night. All are stacks of 750 frames out of 1500. Stacked in AS!2, using 1.5x drizzle, sharpened with LR-deconvolution in Astra Image 4.0 (sigma =3.5, 50 iterations), followed by unsharp masking (radius 20, strength 20). Registax was used for RGB align only, and AI 4.0 was used again for saturation boost. Final processing in Gimp with another round of unsharp masking (radius 100, strength 2), colour balance tweaks, and slight down-scaling to 640x640 (down from 720x720). I chose one image from each of the sessions.

Seeing was quite choppy at the beginning, but got much better later, and I think the latter images are among the best I have ever made. I also very much like the more natural look I get with LR-deconvolution compared to wavelets. As can be seen, the last image was after the meridian flip (which I had postponed as much as possible), which means the image is not perfectly aligned with the rest.

#3 for me, great images Michael.

[Starlight 1]

3 very good like the quality and the marks maid by ( was it a satellites got put in) ?

[SnakeyJ]

Excellent results Michael, particularly the last three. How long does your LR deconvolution take as a process and to estimate the PSF?

Nice images Michael.  I may try your AI4 settings on my images.  I like the wavelets in AI4 but always use Registax out of habit!

Looks like conditions improved with the later images. Would be interesting to see the same data with wavelets Vs deconv.

Your perseverance is paying off well. I like the last 2. Very much. Reminds me of the views i once had on a perfect night with a 14"

Sent from my iPhone so excuse the typos!

Top draw Neil! I can't make my mind up if it's the second or third for me, - sometimes less is more! Well done indeed, - very natural!

Excellent work. Something between 3 and 4 would be ideal.

Thanks everybody for the kind words.

Thanks for  the suggestion, I just checked it out here:

Hi Michael all the images have a yellow red colour cast. to me on here. If you go on to registax 6 and click colour balance. All becomes pure and white again. ridding the colour casts. This will work for all the images. And I know colour is subjective but I think, the colour weight is more even using the registax balance.

Nice shots.

Thanks, Neil, I see that my laptop screen has a blue bias, and on my other screens there is also a colour cast. I will check it out.

Nice work Michael, I also use the technique Neil mentioned to reduce the yellowish color from the image.

Very nice collection of images, the 3rd and 4th are particularly good.
