20th Jan - Ha (w GPCs)

[vineyard]

After suggestion by @Rusted in a different day's imaging thread about how he threads GPCs into the nose of his camera, I thought I'd experiment with that.  And used 1.25x & 2.6x.  The image on the screen is definitely bigger w both (w the 2.6x the whole disk no longer fits on the FOV).  Images are below - where I was able to take more or less the same composition w each of the GPCs I've noted that (hence pls forgive some repeat framings).  In some of the images I also tried different numbers of APs in AS!3 just to see whether there is a dramatic difference.

It's interesting - I think I'm quite surprised by how well the 2.6x GPC came out in ROI tbh, a better sense of dynamism?  I did also try some 2x2 binning but unfortunately the FC txt files didn't capture that (so either I made a mistake & didn't bin, or I should have written it down).

Those are some great images! 

When you change the GPC the image can get brighter or darker.
All depending on the degree of enlargement.

Thanks @Rusted - I like the GPC idea - thank you for the tip, will definitely use that more & more    And now that you mention it, yes the 2.6x GPC definitely seems to give brighter images - that probably also contributes to the more "active" nature they invoke.

A fine set of images there.

Thanks @Pete Preslandthat's v kind.  I am missing the sun - I really hope its clear tomorrow/Sat as was looking possible at some stage b/c I am going to go sit outside!
