Finally getting somewhere with mosaics on my TAL/PST conversion.  Seeing was dreadful, and as you can see not a lot going on (how I miss 2013)

The breakthrough was flats, finally managing to do them properly such that I could see as soon as AS!2 popped out the stacks that I was looking good for a knit.  It's a bit patchy still but for a good effort for me I think.  32 panes of 200 out of 500 stacked, stitched in Photoshop using Photo Merge

Hi Notty,

Well done, thats come really well. How many panels did you do, what camera did you use, what software did you use for the mosaic - was it EQMosaic? How did you stitch them together? Sorry for all the questions

I keep threatening to do a mosaic but alas yet to do / attempt.

Really good mosaic! Nothing wrong with that at all.

[Notty]

Thanks for the feedback guys.  

Michael, I had a read of your excellent tutorial thank you very much for posting it.  Can I ask you about the "Lucy-Richardson Devonvolution" filter... is this a Photoshop feature as I can't find it as an add on.  Maybe there is an equivlant, but all I use is Levels Curves and Unsharp Mask at the moment.

Ian, my camera is a PGR Chameleon and I used Photo Merge in Photoshop and there were about 32(!) panels as previously I'd found out too late that I had areas with not enough coverage for the stitching software to resolve.  As an aside I shot the first images in the Chameleon's highest resolution 1296x964 but I also shot another 38(!) on the lower setting of 640x480 to see the difference.  I also ran these through Autostitch to see how it dealt with them and it stitched them fine.  Not much processing done past the initial pre mosiac sharpening just a superimposition of the disk onto one behind it with the levels turned to catch the proms, such as they were that day.

It's a more even mosaic I think, but the lower resolution really shows.

Great mosaic Notty , well done.

[sooot]

nice work, 32 panes I think you've done a great job, just pull up the sharpening tool in ps and blend in them patchy bits you say are there

[David Smith]

Nice disks Notty.
