Saturn 9th-10th March 2007

Hi All,

Seeing looked good to me, later when I was about the pack up I noticed I could see the Crux from my backyard and the polar triangle easily. I am guessing the seeing was goo from this.

Well a fun night with the LX90, left the dew shield of and I did not note any dew . I think perhaps I was misinterpretation the reflections of the red light torch as dew or mist previously.

I think I saw a satelite tiny dot moving fast in the FOV, while aligning trying to Align on Alderban (about 9pm) using 25mm EP.

As to Saturn, spend a lot of time trying to focus it just right and unfortunately it seems I am still not having much luck. I used Qfocus focusing tool on Saturn until I got a Imax value averaging the highest value it would goto. Anyway I think my focus is still off I will let you guys be the judge.

Tried to use the 5x barlow but I really had to push gain, gamma and brightness to get an image on the screen. I found it quiet difficult to focus at this magnification due to image shift. The Image would move so much that I had to realign and sync every time to start capturing. I had to use PPM to center the images as Registax could not align correctly on any features, given the very low brightness and large amounts of noise.

I think in need to get a 1.25" 2x and possibly a 3x barlow. Also need to do something about my focusing issues. Image shift is an issue at higher magnifications. Is there a quickfix to the meade focuser? That I could use for fine adjustments without causing shift.

All captures were done at 5fps.


Regards
