First light for the Autumn season 2020

 


First light for the season is always a big thing for me personally. I have had really bad troubles to have a imaging telescope. Lots of promises but nothing  happens so i'm out of real tools. I do have a kind of working imaging platform built around an old Tokina AT-x 300mm f2.8 camera lens, here is some info about this toolset, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html

I have an imaging plan but for the first light I selected something more "easy" to test my system after a six months pause due to nightless nights up here near to polar circle. A supernova remnant Veil Nebula in constellation cygnus is a beautiful and large target with some really dim parts and background nebulae.
I have shot the Veil nebula many times during the years with a different optical configurations and it's always shows something new and different, what a fascinating target!


Veil Nebula
Please, click for a large image, it's worth it

Image is in natural colors combined from the narrowband channels. H-alpha = Red, O-III = Green and O-III + 20% H-alpha = Blue.

A full resolution closeup, the camera lens draws beautifully when well collimated and focused.
lots of stars there, star colors are combined from narrowband channels H-alpha and O-III.

The starless version of Veil Nebula makes easier to see very faint details in nebulae otherwise buried under the dense starfield of the Milky Way.

INFO

Veil Nebula locates in a constellation Cygnus at distance of about 2400 ly. It's a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field. I have shot this target so many times over the years and i never get tired to it, ther is always something new to find in it, Here is a collection my photos from this fascinating target, https://astroanarchy.blogspot.com/search?q=Veil+nebula

Grayscale Wonders part IV

All the photos, I have published, are taken with a grayscale astronomical camera. Each color channel is shot separately and then combined to RGB color image. Since I'm doing only narrowband imaging due the extensive light pollution color channels are are emission line images. Most of the time I'm capturing three emission lines hydrogen, sulfur and oxygen. (H-alpha, S-II and O-III)

Usually most of the details are in hydrogen alpha emission line. Gray scale images can be really beautiful and many times I personally like them best. I will publish now some of my images from this winter season as a grayscale compositions. This is a part IV of Grayscale Wonders, part one, two and three can be seen here: Part one, https://astroanarchy.blogspot.com/2020/04/greyscale-wonders.html
Part two, https://astroanarchy.blogspot.com/2020/04/grayscale-wonders-part-ii.html
Part three, https://astroanarchy.blogspot.com/2020/04/grayscale-wonders-part-iii.html

All my photos from the Winter season 2020 in visual colors

I have published this image poster in mapped colors at April 15. 2020
It can be seen here, https://astroanarchy.blogspot.com/2020/04/all-my-photos-from-winter-season-2020.html We have lost the astronomical darkness for about six months, up here 65 North.
Next time I'm going to be able to do the deep sky imaging will be at mid September 2020.

This time I'm publishing the same image set in visual colors.  Colors are combined from narrowband channels emission from an ionized hydrogen, sulfur and oxygen (H-alpha, S-II and O-III) are combined by following method;
Hydrogen and sulfur are both in red channel, oxygen has split between green and blue channel.

I was able to have my imaging system up and running very late, at first week of January 2020. I build my imaging system around an old Tokina AT-x 300mm f2.8 camera lens by mating the Apogee Alta U16 camera with it. Not an easy task due to very large CCD in Apogee camera and lack of back focus distance in Tokina lens.
I even used an angle grinder to shorten up the lens!
Some info and images about my imaging tools can be seen here, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html

I made a poster format presentation about all of my new photos from the Winter season 2020.
There are some very rare images from this imaging season. Photo 2 in poster might be the first three band image of this nebula pair. Photo 12 might be the first color image ever showing this area in sky. Boths targets are dim to extreme and lots of exposure time was needed even though I was using very fast optical configuration  (Under sampled optics, ~6 arcseconds/pixel)


Winter season 2020
A very large image, 3300 x 4800 pixels and 17 MB

All of the photos in this poster has been taken with the Tokina AT-x 300mm f2.8 camera lanes, Apogee Alta U16 astronomical camera and the Astrodon narrowband filter set. (5nm H-alpha, 3nm S-II and 3nm O-III) All photos have been shot from my down town observatory. Location is very light polluted, the sky quality is  Bortle scale eight!
