Re: Widefield MW Dust in Scutum

Full of stars! A 6-hour total exposure test sounds a little insane :) And the data processing procedure is quite sophisticated. If it does not involve paid software, I hope can learn from you. Given 533 is a small-size 1-in sensor, what actually caused the obvious aberrations only in the upper part...

Widefield MW Dust in Scutum

I decided to visit a star-dense area to test my new Samyang 85mm lens. If I'm not wrong, I used f/3.6 for 6 hours on this image because at faster focal ratios the stars were of very poor quality. Overall I am quite happy with the star shape and colour, I used a ZWO UV/IR cut filter to help subdue bl...

I think roughly 3 hours per panel on each filter, horizons aren't good enough to image it for many hours each night

Both were shot in Singapore :)

Milky Way Core Nebulae mosaics: M20 & M8, M16 & M17

M20 and M8 - 2x1 panels, full broadband RGB (no filter) M16 and M17 - 2x1 panels, HaRGB (l-extreme filter used, and its red channel was extracted to use as Ha for enhancement of RGB image) All shot with ASI533MC Pro and WO GT71 scope. Some stars are elongated because I was running unguided exposures...

Beautiful image. SHO on such dynamic targets never fails to impress

Re: Flare at bottom left corner of M51 Whirlpool Galaxy

M51 Whirlpool Galaxy

Attempted M51 with my 6" Newtonian, it is not very well-suited for imaging due to its 1.25" focuser that does not support coma correctors. However, I am still pleased with its performance. Low integration time for broadband data, about 2 hours. L-extreme was used to isolate Ha regions and ...

Carina Nebula in HaRGB

Shot from my bedroom window over January-March, data is not great and the stars are abysmal, ranging from haloes, aberrations and backfocus/tilt issues.

WTB: Skywatcher Star Adventurer 2i Pro Pack

Looking for a Star Adventurer 2i Pro Pack, would be great if a good tripod is included. McGill sells it for $709 and other overseas websites also around this price, so I am hoping to spend a little less. Thanks
