CanonEOSII 6D 'stock-new 2017 model from B+HPhoto' using an OrionSkyGlow 2in. filter thru two TeleVue 2XPowerMates for 4800mmF/L thru a 152mm A+M Refractor(OfficinaStellare) on an Astro-Physics 1200GTO '2010' Mount for two 'one-shotColor' images ... one was 667secISO4000 and the second was 518secISO4000 and they were Sum stacked in MaximDLPro V6.16 and then processed in "ImagesPLus" . The OrionSkyGlow filter causes a 'green' tint and trying to get the 'blue' to show is needed . These images were taken before the morning light .x I tried figuring out the Orion Polarizing 2in. filter and it always has the secondary artifacts when looking thru it at a coil lightbulb …. even a Baader UV-IR filter with a Lumicon MinusViolet filter attached to it has the secondary artifact of the light in the view … so only one filter can be used to image long exposures with artifact free images .x When I 'open' a Canon image from the camera in Canon Digital Photo Professional and 'double-tap' to get the large size to work on it and the 'Tool Palette' to the left side … a small 'icon' is active on the right lower corner for about 1 minute and when it stops the image becomes smoother and more normal .. so it takes some time ; this also might be happening in the DSLRs when an exposure finishes and it might take 1 or 2 minutes to process before the next exposure is started .??. x
