Equipment Used: - TeleVue NP-127 (660mm, F5.2) - TAK NJP Mount (unguided) - Meade DSI-Pro, TV 2x PowerMate Exposures: - L 23x85 seconds - R 21x60 seconds - G 24x60 Seconds - B 33x60 seconds Processing Software Used: - CCDStack - Registar - Photoshop Description of Processing Technique: CCDStack: - Used CCDStack (trial) to register and combine separate L, R, G, B frames - used Poisson/sum data rejection and combination approaches Registar: - Channel alignment Photoshop: - Separate noise reduction in each channel - RGB combine - LRGB framing - Curves, levels, and selective color layers - Gentle sharpening via High Pass, Unsharp (Lodriguss), and NIK Sharpener Pro - Gentle noise reduction in NeatImage Additional Comments: - very difficult night, had to shoot through high clouds - dark - moon was nearing new phase - very thin image - needs a lot more subs, with longer exposure times - final processing was hard to judge, too contrasty on new computer, so I adjusted for old computer - so this may look over-highlighted to you.

Equipment & exposure: - NP-127 - TAK NJP Mount - Unguided - Meade DSI-Pro (Luminance), DSI (Color) - Televue 0.8 Focal reducer Luminance with the DSI-Pro: - 63x2.8 second exposures - 79x5 second exposures - 68x15 second exposures - 63x30 second exposures - 51x1 minute exposures The color information was taken with a Meade DSI-C: - 70x15 seconds subs combined with 61x42 second subs. I used the layering technique outlined in Lodriguss' book, "Photoshop for Astrophotographers" to keep as much of the core details as I could.

Mirror lock enabled. Scope: Unguided Meade LXD-75 SN-8 f/4. Baader MPCC Coma Corrector. Exposure: 1 x 30secs, ISO 1600, Noise Reduction On. Field: 45 arcMins wide (approx.) Cropped to 1600x1200 then reduced to 800x600. Location: Canberra, Australia 29May06 (1200-1300hrs) UTC Processing: Histogram, crop, reduce and unsharp mask in Imageready. The home-made wire-mesh diffraction focuser that I use for selecting focus was placed on the front of the scope for this shot. This yielded the strong diffraction spike on the brightest nearby star.
