The image was produced using Photoshop by manually stacking 30 photos. (DeepSkyStacker somehow failed to stack the photos automatically after several tries)
This was my major target and effort for Calstar 2012. Taken over a series of 3 nights from September 13-16. My first evening under the stars had the camera rotated in the wrong position, so I couldn't use the subs very well. Because the camera position varied from evening to evening, this became an exercise in making a mosaic as well.
Because of the mosaic layout, amp glow from the camera was a big problem. My previous efforts to use DSS and PI to calibrate and stack were not able to sufficiently remove the glow. In the end, I loaded up Maxim, pointed it at darks that were in the temperature range of the lights and let it do a full calibration. The stacking of the resulting 59 fit files were done in DSS 3.3.3 beta 47 as a Sigma Clip. Processing was done in PI where I cropped, DBE, masked stretch, NR, and then a small MT to tighten up the stars. Brought the images into LR3 for touches to fix the blue halos in the bright stars (artifacts from calibration) and some final lines from the mosaic.
Final stack of 59 lights of 10 minutes at 400 ISO. Calibrated in Maxim with 63 darks, 27 flats, and 55 bias. Shot with the full-spectrum Pentax K10D camera with the cooler attached giving temps ranging from 19-21C. Telescope was a Stellarvue SV4 guided with Maxim using Orion SSAG on SV70ED. All used on a Losmandy G-11.

bottom-right ... RA: 04 08 52.468 Dec: +36 43 53.97
Lessons learned: Maxim does a good job with non-linear amp glow areas. I'll be going back to some of my problematic subs to recalibrate. I'll have to see what I can do to fix the blue rings in the bright stars as calibration doesn't seem to control these well.

This is M16 in Serpens also known as Eagle nebula. I collected the images on two evenings. However, I had to discard many frames due to windy and partially cloudy condition, which caused guiding problems.
I am proud that this image was selected as the Astro-image of the week (week 36/2017) in the German astronomy portal, astronomie.de.
For those who can read German, you can find a comprehensive description of M16 and discussion on my picture here www.astronomie.de/aktuelles-und-neuigkeiten/astrofoto-der...

NGC 7380 - Wizard Nebula (Reprocessed) by Paul Hutchinson
Wikipedia: NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. ...
Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer.

Nikon D3100 - Telescopio Sky-Watcher Dobsonian 203mm/1200mm (8") - 100 lights, a ISO 6400/12.800 con DeepSkyStacker - Exposiciones de 1/2s a 1/4s.
La nebulosa de Orión, también conocida como Messier 42, M42, o NGC 1976, es una nebulosa difusa situada al sur del Cinturón de Orión.6 Es una de las nebulosas más brillantes que existen, y puede ser observada a simple vista sobre el cielo nocturno. Está situada a 1.270±76 años luz de la Tierra,2 y posee un diámetro aproximado de 24 años luz. Algunos documentos se refieren a ella como la Gran Nebulosa de Orión, y los textos más antiguos la denominan Ensis, palabra latina que significa "espada", nombre que también recibe la estrella Eta Orionis, que desde la Tierra se observa muy próxima a la nebulosa.7
La nebulosa de Orión es uno de los objetos astronómicos más fotografiados, examinados, e investigados.8 De ella se ha obtenido información determinante acerca de la formación de estrellas y planetas a partir de nubes de polvo y gas en colisión. Los astrónomos han observado en sus entrañas discos protoplanetarios, enanas marrones, fuertes turbulencias en el movimiento de partículas de gas y efectos fotoionizantes cerca de estrellas muy masivas próximas a la nebulosa.

This is a difficult object to image due to its limited visibility from this latitude (50 deg. North). NGC 253 is about 25 deg. South.
Canon EOS 40D, Celestron C8 telescope. 6 x 5, 6 x 4 & 15 x 2-minute exposures at ISO 1600, f6.3. Images registered and stacked with DeepSkyStacker software.
Here’s a single, calibrated light frame using the new ZWO ASI183mm. The exposure was 600sec long and unguided, hence the noise and the streaked stars.
Equipment used:
Canon 200mm f2.8 lens at f4, ZWO ASI183mm camera, AP900 mount, DeepSkyStacker, Photoshop levels, curves.
26x 30 second exposures (I shot 42 exposures but the rest were too poor to use due to vibrations in the telescope mount), shot between 10:26pm and 11:36pm, stacked with Deep Sky Stacker so that the comet, which moves noticeably by the minute, is held still while the stars are allowed to streak.
7.5 inch Maksutov Newtonian telescope F5.3, 1000mm. ISO6400 .. so there's lots of noise in the exposures. I currently have to use a 1.6x barlow lens in the telescope in order to use the camera, until I get the right adapter for this scope. With the barlow, and the camera's crop factor, I was really shooting at F13.5 / 2560mm, so the view is more narrow and dark that it would otherwise be. 13 minutes total exposure time.
This image really only shows the core of the comet, the glowing ball of gas and dust around the comet extends out past all the edges of this image, giving the stars a greenish tinge throughout.
The gaps in the star streaks are time periods between exposures, the bigger gaps are when I was trying to rid my telescope of dew
Comet 103P Hartley is a periodic comet that returns every 6.5 years. It might become visible by eye in October. On this night it had a magnitude of 7.6 and was in the constellation of Cassiopeia

Super cheap kit: Lumix GF7, Asahi SMC Takumar 200mm vintage lens, both from eBay, no tracker or anything, just manual re-pointing every few minutes, 200×1 second exposures stacked with DeepSkyStacker, then tweaked afterwards with RawTherapee (for those that care about such things)
This was taken before I tried to find the Comet Lulin. I took the original picture with 10mm focal length and crop this part out for stacking because the distortion made full-frame stacking with DSS (which does not have distortion correction function) impossible. The bright stars on the lower right are Hydra's head.

A re-processing of old data (omitting the 60 second exposures, which didn't add much). There's a bit more noise come through but there's a hell of a lot more detail showing and all in all I think I'm pretty pleased with the upgrade at such a low amount of time!

Quelques tentatives réussies de capturer la comète C/2012 S1 ISON. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine, bien qu'à l'opposé. Je tenterai de combiner les 17 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.
Some attemps of capturing Comet C/2012 S1 ISON. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, although it was far in the sky. I will try to stack the 17 good files I made in Deepskystacker or IRIS.

My second subject from Saturday night/Sunday morning. I could do with adding a lot more subs to reduce noise. Also the colour balance is too blue; I have tried to correct this, but there was little red in the subs (except noise) as the camera is unmodified for astrophotography.
