Did you have any filters in front of the lens? With or without a filter, I'd suspect some kind of streaking on the lens/filter surface, or sleeks, which are microscopic scratches (usually on coated surfaces) created when you clean them with too much pressure or not using a fluid. I've seen flare li...

Apologies for the late response. I wanted to do the experiment Chris suggested Try taking a test image with the same equipment using a bright, near point source- the Sun again, or something like a halogen light if you're indoors. and did today the same image (same position of the Sun, same camera, l...

Thank you owlice, You’re right about the air traffic: there is a lot of it, as you can see from this photo (another halo :D ), taken on May 4th: http://www.emilivanov.com/Other_Images/2012_05_04_Solar_halo_b.jpg The Sun was approximately at the same point of the Sky. But on this photo there aren't t...

Hello everybody, I’m not sure where to post this topic. If the moderators find that this is not the appropriate place, please, move it. About one hour ago I took this picture of (strange?) 22° Solar halo: http://www.emilivanov.com/Other_Images/2012_05_23_Solar_halo_b.jpg Does somebody have an idea w...

Last night at about 22:30 I was just heading to bed when it began to thunder. I went upstairs to shut the window and saw a great lightnings. I quickly grabbed the camera and did not even had time to put it on the tripod, so I put it right on the window's ledge and started shooting. Here are two imag...

Emnil Ivanov, you are one of my great favorites. I love how you show that there is a "gray bubble" inside the "spaghetti filaments of redness". The structure of this nebula is faintly, faintly reminiscent of the Crab Nebula, where there is also a blue-gray nebula "kept in p...

Greetings, Emil

Emil Ivanov, that's a great-looking Jellyfish Nebula. You have brought out excellent structure in it, and I can discern a large red "S" in its twisting shape. Add the bluish area to the "S", and the nebula takes on a "yin-yang" shape. With the colors you have brought o...

Wonderful !!! I wish I was there :D . In the beginning ISS is overfliyng the US Pacific coast (at 0:16 LA just under the clouds), then Gulf of California, Mexico, Panama (0:31), then Equador and Peru (Titicaca see at 0:47, just before the siurise). Afterwards I can recognize at 0:49 the southeastern...

Sh2-170 ( Rosette Nebula ) :) http://www.emilivanov.com Copyright: Emil Ivanov Often called the small rosette due to its resemblance to the original, this small Sharpless object is five times smaller in size and much less bright than the Rosette Nebula. Therefore it is not a common imaging target. ...
