Subject: guest astrophotography: moon Sent: Wednesday, October 6, 2004 13:13:44 From: Dave Wallace (firstname.lastname@example.org) For your consideration, this shot of our only natural satellite. Taken at approximately 10:45 PM 10/4/04 EDT (0245 on 5 October, 2004 UT), which was only a few minutes after moonrise. Equipment: ETX-90 optical tube on photographic tripod with Canon EOS Digital Rebel 300D camera at prime focus (Meade variable eyepiece projection adapter with no eyepiece installed). Exposure: ISO 800 at 1/5 second with the telescope operating at approximately f/22 (an estimate based on the magnification obtained). Processing: color cast correction, contrast enhancement, flip, rotate, crop, unsharp mask and down-sampled by a factor of about 3 (Adobe Photoshop Elements).

Subject: Astrophotography with Canon A70 Sent: Thursday, August 5, 2004 16:00:24 From: Robert Edmondson (firstname.lastname@example.org) I was considering buying Meade's Autostar Suite and LPI package as an inexpensive entre into the world of astrophotography, but after reading through some of the reviews I began to see that there are many other options "outside the box." I am sure that the Meade product is fine for the money, but when I read about the successes other people have had with modified webcams and digital cameras, I thoguht I should at least try out my Canon A70 before I bought anything. Rather than wait to learn about the optimal ISO speeds and exposure settings for the different phases of the Moon, I just turned off the flash, set the camera to B/W, extended the 3X zoom, and got started. I did not expect much because I would be holding the camera rather than using a mount of some sort, but by happy coincidence the high eye-cup of my Vixen Lanthanum IV eyepieces fit snugly around the main camera lens, and the extended zoom was just the right depth inside to hold it steady about my ETX-70 - enough to image the moon when it was low on the horizon. I decided to buy the $60 adapter kit from ScopeTronix because I was very pleased with the results of my first night out. When you look at my picture keep in mind that I live on the SW side of Phoenix so I am viewing the moon low on the horizon across the entire city after a 108-degree afternoon. I used my 6mm Vixen Lanthanum eyepiece and a Moon filter. I am anxiously awaiting the arrival of my adapter, and learning how to use the AstroStack (www.astrostack.com) software I have read such good reviews about. - Robert
Subject: which camera? Sent: Friday, May 21, 2004 16:16:34 From: Ethan Smith (email@example.com) I've been logging into your site for months now. Great info! I own a Meade LXD55 6" refractor and a Canon EOS Rebel SLR that I have had for a while. Wanted to know your thoughts on using a digital Rebel versus a logitech quickcam pro4000. I know that the rebel costs $1000 or so and a webcam is around $100. I modified my quickcam express, but it has the cmos chip and not the ccd. I'd like to get into some serious digital photos, since I have used 35mm for about 10 years now. Not sure about a dedicated ccd for just astronomy. If I was to spend the $1000, I'd want to use the camera for other things as well. Thank you for your help and time. Ethan Smith VermontMike here: I've seen some really nice digital Rebel photos.
Subject: I have a picture for your website. Sent: Sunday, April 25, 2004 13:02:03 From: "harry east" (firstname.lastname@example.org) I took this picture on the 24/04/04 in the UK with an ETX 105EC and a Canon Powershot A300 digital camera. The image was taken through a 32 mm meade plossl eyepiece. Thanks Harry
