Subject: Early morning ETX-70 observation report. Sent: Friday, October 3, 2003 10:38:06 From: electra188@comcast.net (electra188@comcast.net) I had such a fine session with my scope this morning, I thought I'd better share it. I woke up early (0400 CDST) and set the ETX-70 on the front lawn. The sky was clear with the seeing fairly steady. The light pollution was typical for a suburb of Nashville at 4 in the morning. The temp was 40 Fahrenheit with calm wind. I leveled the scope but didnt bother with the alignment; I wasnt quite awake yet. I slewed over to Saturn and was astonished at the clarity with which I could see the gas giant. I was using a 9.7mm super plossl with a 2x Barlow and an Orion V Block filter. I could discern three of Saturns moons. Titan was visible with direct vision, with Rhea and Iapetus visible with averted vision. I wasnt sure about Iapetus, which is around 11th magnitude (This being near the limit of the ETX-70 at 11.5 magnitude). But confirmed it with software when compared to my sketch. The view of Saturn was fantastic. Then I slewed over to beta Monoceros. I had never been able to split this triple star with my ETX-70 before tonight. I started with the 9.7mm and Barlow with the V Block filter. It split into two components. Then I tried a 6.4mm and Barlow with the V Block filter and was able to split it into three discernible components. Then I spent a little time on M44 the "beehive" with a 12.4mm super plossl. Then off to the "seven sisters" M45 beautiful as usual. But M42 the "Orion nebula" was the belle of the ball tonight. I used a 6.4mm super plossl with an Orion Skyglow filter. M42 just dominated the eyepiece with M43 glowing right along side. It was the best view of M42 I have ever had, in any scope. Then I thought I would try the "Horsehead". So I dropped the 26mm eyepiece with Skyglow filter into the scope. Then slewed over to "Alnitak" and started to look. No "Horsehead" but I could discern the darker area of B-33 as compared to the adjacent sky. No detail though. Im just going to have to find a darker site if Im going to see this jewel with the ETX-70. Not bad for an hour and fifteen minutes of observation this morning. The ETX-70 is a fine little scope and I thoroughly enjoy using mine, with or without the Autostar. Thanks Mike for all of your efforts which make this just a great site and resourse for all ETX owners. Sincerely, Tim Haller...electra188
