At last, at the end of this week , we had fair weather up here in Sweden. So I took the opportunity to catch some avi´s with my new DBK 21AU04.AS colour camera. At first I managed to capture 3 avi´s before the clouds came rolling in... the seeing was really bad, sometimes everything blurred up into a gray ball.. About an hour later, the clouds had passed and it was clear again! This time I shot about 15 avi´s with different camera settings. The seeing was a little bit better than before, but still hardly mediocre. The scopes I used was my Vixen ED100SF and my friend Magnus´s Orion Optics 8" f/6, 1/6 PTV reflector. For magnification I used an Intes 2,4X Barlow lens. With the Vixen refractor, I used an ir/uv blocking filter. No filters was used with the reflector. The first thing I found out, was that I need more power to "fill out" the chip. And with the DBK camera, (on Saturn), I will have to use at least an 8" scope to resolve Saturn "properly"... I had to set the gain setting at maximum to even see it on the screen, with the Vixen 100... We had our gear set up on Magnus´s balcony, so his CG5 GT mount was used this night. He also was in charge of the hand control to track the planet, while I was busy operating the camera and focusing. As this is my first effort to capture Saturn, I can´t be too dissapointed with the final results... I will be most grateful for your opinions and thoughts, how I can improve the results! -A more powerful Barlow lens, eyepiece projection, a bigger scope? -All suggestions are welcome! I also have an Orion Optics 8" f/6 1/4 ptv. reflector, and an Orion Optics OMC 140 mak, that I am going to try as soon as the weather allows. This picture is shot with the Orion Optics 8" f/6, 1/6 PTV reflector. Kind regards/Roger!

As you see, a 2,4X Barlow wont enlarge the image enough... I am afraid that if I use higher magnification, the image will be too faint, when using the Vixen 100... Perhaps eyepiece projection is the right way to go? Post Extras:       solshaker Carpal Tunnel Reged: 06/06/06 Re: My first Saturn...

Until I have got me a new, more powerful Barlow, I´ll either use my OMC 140, because of its focal lenght (2000 mm), or my Orion Optics 8" f/6, with eyepiece projection, to enlarge the image on the sensor. /Roger!

Your 8 inch has the same focal length as my telescope and I think I get a good image scale with a 3x barlow. Add a 5x if you need more Post Extras:       Trever Post Laureate Reged: 08/18/03 Loc: North Alabama Re: My first Saturn...

It really depends on the seeing conditions, camera settings and optics used. You are on the right track though! Looks great!. Post Extras:       Pages: 1
