Continued 2x2 panel inserts using the Trius 814 and H694 camera.
The North America and Pelican Nebulas - Narrow Band Hubble Palette 2-Panel Mosaic

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest
star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. It is sometimes
incorrectly called the "North American Nebula".  

The Pelican Nebula (also known as IC 5070 and IC 5067) is an H II region associated with the North America Nebula in the constellation Cygnus. The
gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is divided from its more prominent
neighbor, the North America Nebula, by a molecular cloud filled with dark dust.

Imaged with the following equipment:
- Tak FSQ-106 reduced with a Trius 814 mono camera - two frame 'detail' insertion mosaic
- EF200 Canon lens with a SXVR-H694 camera - two frame wide field mosaic.

The below image is two camera, two panel mosaic presented in a modified Hubble Palette.  It consists of a wider field image totalling 9 hours in two panels using the EF200 Canon lens
and the SXVR-H694 CCD.  Inserted into that is the detail from a narrower field of view Ha imaged over 6 hours using a Tak FSQ-106 with a reducer and a SX-Trius 814 camera.  Total
hours of data total 14.  Simultaneously captured through the two imaging trains mounted on a Losmandy G-11.  
5 hours of a 2x2 panel Ha capture done with the
Trius 814 were inserted as luminance into the
larger field 2x2 panel done with the H694 and
Canon lens.

Trius 814 Camera.
As you can see from the zooms to the right, the
Herbig Haro object 555 clearly shows gas jets at
the tip of the column.  The SX-Trius 814 camera
provide a great resolution.  

With its' Sony ICX814 SuperHAD ExView chip a
pixel size of 3.69x3.69 micrometers.   Combined
with the Takahashi FSQ-EDXiii refractor and a
.73x reducer (resultant focal length of 385mm),
this results in a very optimal size of 1.97"/pixel.
NGC 281 - The Pacman Nebula - Narrow Band Filters - Modified Hubble Palette

NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes the open cluster IC 1590, the multiple
star HD 5005, and several Bok globules. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game
character.  All of the peaks of the columns you see in this image point at the open cluster of stars in the center whose solar wind blows back the gas
and dust.  It is at the apex of these columns that new stars are formed.

Imaged with the following equipment:
- Tak FSQ-106 reduced focal length to f3.6 with a Trius 814 mono camera
- Capture: Nebulosity, PhD - 14 hours - 20 minute exposures
- Processing: PixInsight, PS4
