<\/p>\nDespite the high thin clouds, I managed to get some failry decent sequences out of my setup. Last night was the first light for my William Optics Zenith Star 66 SD and the counterweight system…oh man, I wasnt disappointed \ud83d\ude42<\/p>\n
First up, yet another M57, and the first one I`ve captured with some nebulosity round the edges. (Almost cerainly due to my installation of Bob’s Knobs and collimating it to within an inch of its life!)<\/p>\n
OTA: NexStar 8 GPS @ f\/10
\nGuiding: PHD + WO66 + DSI (yes, was subpixel guiding at FL 388mm @ f\/5.9 without too many hiccups)
\nCamera: Canon 350D (unmodded)
\nSequence: 10 x 240 seconds @ ISO800 (+ 5 darks, no bias or flats)
\nStacked: Deep Sky Stacker
\nPost Process: PSCS2 + Noels Astronomy Tools
\n(Note:This is cropped but not reduced from RAW image size)<\/p>\n
<\/p>\n
Next M31, and I`ve been waiting for this one to peek its head over the roof\/gutter for a few weeks now. For thisone, I reversed the imaging\/guiding train, so the WO66 was imaging and the NS8GPS was guiding.<\/p>\n
OTA: William Optics ZenithStar 66
