I purchased a GSO 6" f/4 Newtonian "Astrograph" late last year and eventually found that stars on one corner were egg shaped while taking images. I narrowed it down to improper centering of secondary mirror from the factory and resulting tilt.
Long story short, after numerous iterations, I used the Advanced Newtonian collimation technique by Astro Shed guy and ended up with the below pic of the optics. Does it look ok or do I need to do more? I will be checking with a Howie this weekend too.
GSO 0.20 m
Sky-Watcher NEQ-5 Pro SynScan mount
ASI 120MC + IR/UV Cut filter
GSO barlow lens 5x (APO)
ZWO IR/UV Cut filter
f: 5000 mm
The newton in action! 😀

This is a de-rotated image from the three videos used to make up my Jupiter rotation animation from earlier.
The three stacked images from the videos were measured and derotated in WinJupos and stacked. This new de-rotated image had additional wavelets done in RS6 and final processing including a sharpened base layer and a top layer at 80% fill with a Gaussian blur attached.
The original videos were 1000 frames; recorded in EZPlanetary, centred and cropped in PIPP, stacked in Autostakkert2, wavelets in RS6 and final processing in PS CS4 Extended.
Equipment: C9.25, CGEM, RA 2.5x telextender, Zwo ADC, Neodymium filter, QHY5LIIc
First time imaging since April of last year!
Managed to grab three 1000 frame videos between it being dark enough for me to see Jupiter and it going behind the row of 40 foot Sycamore, Oak and Beech trees that back onto our garden.
Scope: Celestron C9.25; Mount: CGEM; Camera: QHY5LIIc; Lens: Explore Scientific x3 Telextender; Capture Software: EZPlanetary
3 x 1000 frame videos, centred and cropped in PIPP, stacked & RGB aligned in Autostakkert 2 with wavelets done in Registax 6; post processing and turning into a GIF. in PS CS4
Seeing was very poor with some very high thin cloud. I think my focus was also off and as I haven't used my scope in anger for well over a year the collimation is probably way off. But hey-ho, at least I've finally managed to enter something into one of these competitions instead of living vicariously through others efforts! 🤪
