Re: My astrophotography 2021

Mars on a steady path towards M44, and will make a ~3-day-long transit through the star cluster around June 23. Stargazers wish for clear skies! https://lh3.googleusercontent.com/pw/ACtC-3fUmoreNCv6hpVVnnRgf5_gWvQaAVKNYh2TE7U9lARfGEW5Hab4Bx1RkRMAE6aX90hH4Ce7xWA3XP4u39g0Z65WJ5pJRoWnNuWXF9JP0xFftwroFk...

Re: My astrophotography 2021

Venus steadily gains brightness. Now at -3.9. It easily creates its halo in the colorful evening cloud just after sunset. In Dec, it will brighten up to -4.7, which is even twice as bright as it is now. Too bright to have any good friend. Aha! https://lh3.googleusercontent.com/pw/ACtC-3e7SKAsEPXL3k5...

Re: My astrophotography 2021

2021-6-16 evening Moon travels in the Leo, and outshines the sickle. The thin clouds just did not go away. But perhaps they actually add to the otherwise dull background. The moon image is of course a superimposed one. The huge dynamic range of the super bright object would hardly show any details o...

Re: My astrophotography 2021

Finally, the exposures of 7P/ visiting the Helix were done this morning. But was struggling with image processing. The end result for now. https://lh3.googleusercontent.com/pw/ACtC-3fxQOADmsvkWwzt3V5FERnCTnAs5HE-wCg7pjdfD-pwUeXRax3JsuoXwksEnDEcsiEqDn3cSG_qfBEg0vbXzc-Am5fHz9m5lS_Nz8Z9G3lrDDyjiCyopEsM...

Re: My astrophotography 2021

2021-6-15 The faintest object I have ever taken a photo of. The asteroid Gonggong (共工). At magnitude 21.5, it turns out much more difficult than I expected, barely discernable from 4x5min-exposure with a 20' telescope at the Bortle 1 site. https://lh3.googleusercontent.com/pw/ACtC-3cnROI3-u1uplKg1yH...

Re: My astrophotography 2021

Another celestial event captured. (4) Vesta passes by Leo Triplet. (4) Vesta is the brightest asteroid, which happens to transit the field of Leo Triplet galaxy group around 2021-June-11. Difficulty to capture due to the low altitude after astronomical twilight ends -- the Spring stars are leaving t...

Around June-15, the comet 7P will pass by the Helix closely.

Re: My astrophotography 2021

So here you go the NGC7293. Phase 1 of an imaging project in which I choose a wide field to capture something about to happen. Thankfully to the high-res camera, the heavily cropped image of the nebula is not too bad in terms of details. https://lh3.googleusercontent.com/pw/ACtC-3eeUjovVN8dPR8NzN37h...
