GT AUDIO WORKS

Thanks Bryan, Displaying in 256 ? You lost me. Yes I cleaned the sensor first thing..other than a few spots went away..no improvement. Greg

Thanks James, I shot the first one with a 28mm at about 5 seconds at f2.8 ISO 2500. This processing was deliberate to bring out the flaw.... But now that I look at the frame in the camera monitor the color banding is apparent unprocessed as well..guess I didnt notice it in the dark last night. So my exposure is too short. So how far can I stretch the shutter time before star trails appear..And how far can I go with boosting the ISO ? Greg

Hello All, I have just recently gotten back into photography after a long hiatus...my last decent camera was film...so its been awhile. Got myself a used Sony A7 and a few vintage Olympus Zuiko prime lenses so all the AF stuff is rendered inoperable which is OK by me. All has been going well with daytime shooting, so I decided to give comet Neowise a shot. I am having an aberration show up on all my shots with different lenses when I process the image. I took this shot of some stars and I purposely boosted the brightness and color to accentuate the issue. The other shot of the comet you can see the same issue I am pretty much flying by the seat of my pants with this digital stuff. Any expertise would be appreciated. Any ideas ?
