I was perusing this thread, but it's been somewhat crippled with the deletion of all the images during the regular database pruning...

Yeah John, too bad, eh? I think Fordy is compiling a final report out of this to go into the KB, might want to ask him if he has the pics.

Unfortunately not, mate - Hopefully rob can retrieve them from a backup - Then I'll compile the article.
I also want to do my LP fuilter comparison and focal reducer shootout as knowledgebase articles too, but may need to get those images beore I start :-\

Oh yeah, the LP filter shootout was great! :cool:
Definitely bring those back if you can, I may actually dig mine up if you want them. Heck, I'll even do a ccdinspector on them!

OK let's add an image to this thread...
No chromatic aberation in this one as it's mono
but there isn't any anyway
SV4 at prime with SXV-H9 and CLS filter (which blobs the stars a bit more than without - I forgot to take it out for these shots :roll:). The image is at 50% full scale with 100% inserts.
I am still having problems with 'sag' in the image train as you can see towards the right hand side - I hate push fittings!
