In this instance the subtle lens flare on the bottom left adds a subtle summer vibe. This was taken with a lens hood attached and just a touch of light hitting the front of the lens. Without one the excessive light on the lens would have ruined the shot – see next image. This image...
The utility model relates to a device to carry out times rotation and separation for an imaging beam in an optical axial plane which is vertical to the imaging beam, and the utitity model is positioned on a 135 camera lens. The device carrying out more times separation and exposure for a...
Further, it has been demonstrated that the proteomic profiles of EVs from the same source are dependent on their isolation method [2]. The field of EVs has led to much understanding in the area of cell–cell communication and cancer metastasis, and their use in the clinical setting as ...

The only time ive had any rings in post processing using my D5600 has been when I've been under a lot of light pollution. I'm certain it was internal reflections and scatter from the lens hood #239 Colonist Sputnik Posts:30 Joined:20 Jul 2018 ...
Something along the lines of a setting that boosts the shadows to try to retain detail in the dark regions of an image? Hope this helps. Hi Scott, Thanks for taking a look at these. I'm sure there wasn't anything changed, it's just not that complicated: a 180mm lens on the camer...
in seeing a series of ISO 200 flats taken with that lens at a series of different exposure levels starting with the back-of-camera histogram peak halfway across and then becoming successively more under-exposed. The pattern of concentric rings will then help confirm what is going on. ...
lens hood on the SpaceCat screws on so I know that there is no light leaking in at the base either. Here's an imgur album with some examples of the issue in Siril:https://imgur.com/a/WZBi51l. The example images are 30s exposures taken with no filters. A full compliment of fla...
on than just an overloaded mount. Long exposures still had some trailing too, even with guiding under .5 rms so figured it must be some differential flexture and came up with the easiest solution for now, carved a plastic block with radius of lens and secured to the plate. Around the ...
