Mars 16th from tassie-reprocessed

[davidpretorius]

Hi, did an asi and handpicked 200 out of 300 from that night.

Am very happy with the blue in astra image.

Bottom left is the registax output, then each of the colours after splitting have had a 3x1.3 LR deconvolutioin and a 3x2 ME

the 1st combine is the lr's with no colour adjusting, the secong combine is the me's with colour adjusting.

What made me start was looking at Rumples from the 12th and the face was very simliar 4 days later

Hi DP, I'm a bit shaky on the whole deconvolution thing - LR and ME etc - it's an aspect of imaging that's still just words and letters to me. What does it mean/do, how do you do it and in what program? :confuse3:

cheers,

Nice job! Hand picking frames is worth it....I'd hate to do that in a 3000 framer though! (Iv'e hand picked 1500 & that was enough!)

not sure on the maths side of things, Bird or Rumples will be the guru there, but it helps bring out more detail a bit like wavelets

Astra image you can download a evaluation version from my webserver http://precons.com/iis/downloads/ai25max.zip or the net?

You get your final image out of registax and then split the colours into rgb, or you may have them separate already.

in astra image, you then try different settings for ME and LR deconvolution (3 and 1.3) are popular choices.

you then recombine your images, align them and colour adjust and you have your final image apart from any unsharp masking etc

i cover some of the astr image here

Now out to do some mars!!!

Thanks DP!:) Hadn't viewed your instructional stuff before - impressive and generously informative, you may well be responsible for starting up a Dob-Toucam revolution of planetary imaging;)


cheers,

Thanks for kind comments, but this style of imaging started for me, by following in Iceman's footsteps. He has since got a tracking platform & I will follow with getting tracking as well.

Last night in point.


Temperature difference between mirror & ambient .3 degrees = Excellent
Collimation = still great
Seeing with an eyepiece = average say 5/10
Guide scope aligned
At the end of the day, mars was moving around so much, it was not worth the 1 hour spent to try and focus and align to the viewer.

Tracking will quicken this job up!

So nothing to work with unfortunately

Very disheartening - but thems the breaks!

So out came the eyepieces and I had a loveley 1 hr scan of the heavens with all my usual suspects for this time of the year
