My final image of the Horsehead Nebula (IC434, B33) for the year. I was hoping to add another couple of hours worth of subs, but it was not to be as the last set of images were taken after the camera had been removed and reinstalled. I’ve never been able to get the camera to […]
The following image is composed of 24×600 second subs, Ha filtered, taken on March 9th and 10th. It has much less noise than the previous image. It will be interesting to see what happens with another couple of evenings worth of subs added. Horsehead Nebula (B33, IC434) – Ha filtered Part of the noise in […]
Of course, this is the Horsehead nebula (B33, IC434) in the constellation of Orion. It was imaged over two evenings, after several days of frustration with flaky mount and camera connections. I was hoping to capture more data this evening to help decrease the noise, but it turned out to be unexpectedly cloudy, so the […]
Another view of the 02/20/08 lunar eclipse. The same source images as were used as before, but they were composited differently. Although the color is wrong, I think that the image works much better than the one that I put up yesterday.
Once again the dragons have attempted to eat the moon—once again they have been driven away… I only managed to capture a small portion of the eclipse, but here is a composite of the images showing the moon exiting the earth’s shadow.
The following is an Ha image of the heart of IC1805. Guided, 97×300 seconds, ZS 80 ED II, DSI Pro II with Razorback cooler, Ha filter. For a wonderful image of much more of this nebula see this image on Wolfgang Promper’s CCD Images site. The shorter sub-exposures have improved the star shapes significantly. At […]
I’ve posted my first image to a website (Cloudy Nights) where more than a couple of people will see it. IC1396/Vdb142 in Ha For a really excellent picture of this section of IC1396, follow this link to the one on the Panther Observatory site.
Another attempt at the western portion of the Veil Nebula (NGC6960) using narrow band filters. The orientation of the camera is better than it was for the previous Veil images, so more of the nebula is visible. Some tracking problems remain, mostly in the Ha channel. The usual equipment and about 2 hours worth of […]
One would think that a laptop screen would be the ideal light source for taking flats. One would be wrong. The flats taken using a laptop screen fall off horribly in the corners, making a so-so image look really awful. It turns out the flats produced using the laptop screen as a light source are […]
The following images are of the western portion of the Veil Nebula (NGC6960), also known as the Witch’s Broom, and were taken this last Friday and Saturday night. No flats were used, as the CCD or the filter fogged over before I had a chance to take them on Friday night, and operator error resulted […]
