Equipment

LX200ACF 16" and SBIG ST-8XME. To get focal lenght down a Lepus 0.62x reducer was used.

Description

The Bubble Nebula is shown in so called 'natural colors' using narrow band filters. RAW data used for making the picture, LUM=26*1min.+5*2min. Ha=18*5min.+4*2min. OIII=18*5min. SII=5*5min. Small mix of old color data added to the shown L,80Ha20SII,100OIII,85oIII15Ha picture. CCDStack2 and Adobe Photoshop programs used and all the subs were calibrated before stack with dark, flat, Darkflat and bias frames.

Equipment

Barndoor Mount with unmodded 50D and 50mm 1.8 (@f/4). I also used an Astronomik CLS clip filter to try and bring out the North American Nebula more. Over the course of two nights: 80-90x(30s,1min,2min,4min and one 8min) 30 darks 20-25 flats 20-25 dark flats about 30 bias Stacked in DSS and processed in photoshop.

Description

This is the Cygnus area of Milky Way, an area I've been practicing on most of the summer. I'm amazed at how rich this area is on a clear night! This image is the result of many nights of practice, both in learning the process of imaging and how to handle in post work.

The source data was taken with a Takahashi FS-102 and a SXV-H9 CCD camera using Baader NB Filters. Ha 16*1200 Binned 1X1 [OIII] 12*1200 Binned 1X1 [SII] 10*1200 Binned 1X1

Description

I put this montage together to demonstrate the various ways narrowand data can be processed, by assigning to diferent color channels, to accentuate the chemical compositions of the emissions. Clockwize from the top: 1. Ha[OIII] Bicolor 2. RGB = Ha[SII][OIII] 3. HST ( RGB=[SII]Ha[OIII] ) 4. CHFT ( RGB = Ha[OIII][SII] )

Description

This image shows IC 5146, also known as the Cocoon Nebula. It is both a reflection and an emission nebula about 3300 light years away in the constellation of Cygnus. A reflection nebula reflects the light of nearby stars, while an emission nebula is formed when light from nearby stars ionizes the gas and makes the nebula glow. This nebula does a little of both. The IC 5146 actually refers to the star cluster at the center of the nebula while Sh2-125 is the actual nebula. The nebula is about 15 light years in diameter. You can also see the dark nebula Barnard 163 which surrounds the nebula and forms a dark trailing cloud extending to the west of the nebula (to the right in the picture.
