Hi all
This is my first light image out of my new telescope, a 12" GSO newt on an EQ6. Used the 3x barlow instead of the 5x due to too much drift (no time to drift align!).
The larger image scale and light gathering of the 12" (over my old 10") is definitely noticeable! Unfortunately I overexposed the green channel at the STropZ, which had good transmission on that morning!
Seeing was quite good, and Jupiter was at 46° altitude during this capture. It was the best out of 7 avi's captured between 5:20am - 6:00am local time.
Some good detail is visible, including a red bar and white spots in the SSTB, and another red bar/spot in the SEB just past the meridian. There's also a few white spots on both the top and bottom borders of the NEB. There also appears to be a white spot at the bottom (north) edge of the GRS, and the usual darker patch inside the GRS.
Each channel was captured for approx 45 seconds, at 15fps (1/15s exposure). 330 frames of each channel were stacked in registax, mild wavelets, and LR deconvolution and recombine into RGB in AstraImage.
In Photoshop, gave high-pass filter for additional sharpening, adjusted the contrast/curves and final presentation.
Can't wait to use this 12" some more now!
Thanks for looking.
