Jupiter 23/04/2017

Jupiter on the 23rd April, 2017. Io, Europe on the left and Callisto on the right of the planet. This as I continue to improve the collimation of the C11 Edge HD. Bob's Knobs are now in place, which help a lot! This is the result of a quick collimation after the installation of the knobs.

Thats very nice - and collimation of an SCT isnt something I'd want to tackle!

Also looking at the info I see you have AS!3 - I thought that was a typo but looking it up I see theres a new version. How did you find it compared to v2?

[rodrigol]

V3 seems to simplify things. I personally think that AS!2 and AS!3 are close but one thing is noise reduction seem to be better in V3, though I'm not the one to tell ;-)

Below are new processing efforts with AS!3 and PI(!), which I decided to purchase as the effort to go via RS was too much for me and in no way is this a criticism of that software (just me being impatient!). This took me <2 minutes to clear out of the raw using Atrouswavelettransform, which is similar to wavelets processing in RS, SCNR and Unsharpmask.

[Tommohawk]

OK thanks for that.

I guess the way for me to find out exactly how different it is would be to try it for myself - especially if it simplifies things.. I'm all for that!

[rodrigol]

Go for it. Don't forget to play with the noise reduction. It makes a huge difference and can help you avoid using another piece of software that may either reduce data quantity and quality or worse, introduce unwanted artifacts.

The other thing I forgot to mention is that I think positive progress is being made with collimation thanks to Bob's Knobs. Sorry for the free ad here but "Hurrah for BKs!"

 

[rodrigol]

Another example of PI processing. This time I did: 

ColorCalibration

ATrousWaveletTransform (lots of iterations here, to get best noise reduction)

UnSharpMask

ACDNR (best noise reduction here)

[Tommohawk]

Thats nice too, but image now maybe a bit small to see detail?

[rodrigol]

The above is the full resolution image from the asi290. The detail is still blurry if you zoom in too much because the collimatio  is still not perfect and there are processing artifact. On a desktop computer screen it looks okish. But you are right, its small.

Nice result! Quite a bit of detail coming through.

[Pete Presland]

Nice capture, its nice to see a wider view with the moons showing. A/S3 sounds interesting.
