Name: Jacques-Andre REGNIER Date: 07/07/04 Object: M57 Details: Telescope: Celestron NexStar 5i at f/10 Camera: Philips Webcam Vesta Pro with long exposure modification and BW 1/4" CCD Sensor. Exposure: 229 exposures of 15 seconds each for the luminance channel; 3 x 20 exposures of 20 seconds each for the RGB channels Site location: My backyard located at Etréchy (France) Any other pertinent information: IR-blocking Sirius Optics NIR1 and R, G and B color filters from the Scopetronix filter set I won from the SCT-User 2003 Imaging Contest ;-)) Processing: Frame capture done with Astrosnap; Selection, dark subtraction, registration and stacking, Richardson-Lucy and wavelet processing with Iris; Color compositing (LRGB) and final enhancements (RGB balance, curves, levels and color saturation adjustment, unsharp masking) with Photoshop. Name: Brent Maynard Date: 04/28/05 Object: M5 Details: Telescope: C8-SCT @f5 Camera: Philips Vesta Pro 690 SC1.5 Exposure: 60-15 second exposures Site location: Hurricane, WV Any Other Pertinent Information: CG5 mount, homemade focal reducer. Processing: K3CCDtools used for long-exposure capture, Registax3 used for stacking, Paint Shop Pro 7 used for Histogram stretch and color channel tweaking. Name: Steve Bodin Date: 04/30/05 Object: Ghost of Jupiter Details: Telescope: Meade 16 inch SCT at f/10 Camera: DX8263SL video camera Exposure: 2 second frame integration; stack of 96 images for about 4 minutes of total time recorded to videotape. Site location: Mattawa, WA Any Other Pertinent Information: Poor seeing and poor transparency conditions. Processing: Stacked with Registax3 and dark frame subtracted, enhanced saturation and contrast in Picture Window 2.0 Additional Thoughts: I have seen the long exposure CCD images and while they show the faint details better, this shot looks more like the eyepiece view but with more saturated color.
