The North America & Pelican Nebulas

My final image from Oregon Star Party. I had quite a bit of difficulty just getting this image to upload to the blog, and tried many different strategies all of which broke WordPress. The difficulty arises because of the high resolution and large file size; the final image is 4713×3144 pixels and over 21MB, and…


The Elephant’s Trunk Nebula

Number 2 in my set of images captured at this year’s Oregon Star Party. This is part of the emission nebula known as IC1396 in the constellation Cepheus, featuring a formation known as the Elephant’s Trunk Nebula. This large cloud of mostly hydrogen is about 2,400 light years away from us, and although much too…


Inner Workings of the Milky Way

              Number 3 in my set of images from Oregon Star Party. This one includes emission nebula NGC6820 surrounding open cluster NGC6823 (see annotated low-res version), again in the direction of the core of the Milky Way from our viewpoint.¬†Also visible are many dark clouds of dust, in addition…


Dust Clouds in the Milky Way

              Image number 4 captured under the incredibly dark skies at Oregon Star Party last week. This image features several clouds of interstellar dust that appear as reflection and absorption nebulae, centered on the reflection nebula van den Bergh 126, and surrounded by several absorption nebulae that appear in…


Gamma Cygni Nebula from Oregon Star Party 2015

Still reprocessing old data using PixInsight, now that I have a better idea of the process flow. This data was captured at Oregon Star Party last year, but my initial processing (using Maxim DL) was not particularly satisfactory. No doubt I will come back to this again at some point as I add additional steps…


Repost: Cepheus OB4 from Oregon Star Party 2014

Final (for now) process of images of star forming region Cepheus OB4 captured at Oregon Star Party. To the left of the image is diffuse nebula NGC7822, with the OB4 complex to the right. The bright star just below center right is BD+66 1679, a magnitude 5.7 K1 star which is the only naked eye…


Reprocessing: M45 from Oregon Star Party 2014

M45 captured at Oregon Star Party in 2014. This was somewhat opportunistic; I hadn’t imaged this object in a long time, and hadn’t planned to this time around, but after opening the door of my trailer at 2am and seeing it in a perfect position in the sky to image, decided it would be worthwhile….
