Scope: Megrez II  f/4.2, Location: Laguna Mountains, CA   27 August 2005  Camera: Artemis285

Exposure: 10 x 180 sec Luminance exposures with IR block, 6 x 90 sec (2x2 bin) RGB exposures.

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart.  Channels were co-registered in Astroart. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Selective sharpening with layer mask was applied to galaxy dust lanes. Brighter star sizes were managed with a curves compression applied with mask.  SGBNR was used to smooth  background noise on the final result. Final Image size is approximately 1392x1040.

North is up in this image. The image was guided for all exposures. M33 is a prominent member of the local galaxy group including our milky way and M31 Andromeda galaxy. M33 contains a large nebulous region called NGC604 as well as numerous distinct NGC and IC objects. The second image on this page (see below) is a closer in view and rotated left. The image below shows NGC604 in a little better resolution  This image replaces an earlier image that can be seen in the Archives here.  Horizontal FOV is 93'

Image center is approximately - Equatorial 2000: RA: 01h 33m 52s Dec: +3039'29"

Scope: C8  f/3.2 and Megrez II f/6.25, Location: Laguna Mountains, CA   4 September 2005  Camera: Artemis285

Exposure: 13 x 120 sec (C8) and 6 x 240 sec (Megrez) Luminance exposures with IR block, 6 x 72 sec (2x2 bin) RGB exposures (Megrez).

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart.  Channels were co-registered in Astroart. The C8 stack was  the main image for the luminance construction. The Megrez exposures were used to correct the distortion in the edge stars from the larger CCD and the Meade FR.  Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Selective sharpening with layer mask was applied to galaxy dust lanes.  Color balancing and final touches were done in Photoshop. SGBNR was used to smooth background noise on the final result. Final Image size is approximately 1392x1040.

North is to the left in this mirrored image. The image was guided for all exposures.  Horizontal FOV is 42'
