M8 (Lagoon Nebula)100 viewsCaptured during a cloud lull at main objectives n/o 8/11/2006. Shot through narrow slit between house and trees. M8 was at 15 degrees alt over garage and neighborhood houses. I wanted more exposures, but the third in the sequence showed the nebula going behind trees.
Primary: LXD-55 mount, Nikon 200mm f/4 lens, Astronomik Halpha filter, SX MX716 camera, Astroart 3.0.
Guiding: T80, Vesta, GuideDog (ASCOM).
Image Processing: Astroart, Paint.Net:Resize, DDP, bloat reduction, unsharp, curve adjustment, resize.

IC5070 (Pelican Nebula)77 views8x120s; guided by GuideDog w/Vesta webcam through LX-200 10" f/10 + 6.3FR; captured, stacked, processed with AstroArt 3.0; post-processing with PaintShop Pro 8.0
This was my first use of the 135mm/Ha combo on the LX-200. I planned on 60m of exposure but was cut short by clouds.

NGC7000 (North America Nebula) Mosaic (2005-09-26)327 viewsThis mosaic consists of 4 images each with 15 subframes exposed for 2 minutes. The location was Julie Lane Observatory.
The optics consists of a Nikon 135mm SLR lens attached (using a Mogg Nikon/M42 adapter) to a Starlight Xpress MX716. The filter used as an Astronomik Ha filter. The optics were mounted on an LX-200. Guiding was managed by GuideDog. Image acquisition was done by Cartes du Ciel. Image capture was by AstroArt. Postprocessing was done by AstroArt, PaintShop Pro and AutoStitch.
All telescope and camera control for acquisition, capture and guiding was operated remotely via a wireless LAN.

Veil Nebula (NGC6992/5) -- East Portion191 viewsCaptured at Julie Lane Observatory North with 15-day old moon glaring down. 20 (out of 20!) 4-minute exposures captured in AstroArt; postpocessed in Astroart; final touches in Paint.Net. Autoguided with Stellarvue SV80L, Mogg focal reducer, modified Philips webcam and GuideDog (via ASCOM).
This is the first use of the Nikon 200mm f/4 lens purchased in 2005 and it was quite impressive: I used the lens at f/4 and achieved very tight focus.

Images were captured, calibrated, stacked and processed with AstroArt 3.0. Postprocessing was with Paint.Net. GuideDog, a Tasco 80mm f/5 scope and a modified webcam handled the autoguiding.
Tracking and guiding were erratic this night.
