2021-6-24 Last evening's shooting took a toll such that I had no energy to get up in the wee hours to shoot the stars. Nevertheless, in the pre-dawn time I was excited by the clear skies and what it could mean to the sunrise vista. At around 6:20, the twilight was already a bit bright over the easte...

The tower, now my favorite structure for landscape astrophotography https://lh3.googleusercontent.com/pw/ACtC-3eAe7LRI84fjs8pxvNYBAVX-ANkVsRCBULLfNwqPvBWAEmv6wq5u3H9bwAyfj1B-WoEuMG5TMWNUGT1-glrhfTkXvhY_xkBXid5oV4h68XcYPbKA9BUDtOplSNRn3qJ6a6zrIk7HfoK5T8O_9UGXzRzvQ=w612-h919-no?authuser=0 https://lh3....

2021-6-23 lovely evening Mars now transits the M44 star cluster https://lh3.googleusercontent.com/pw/ACtC-3cEX1nhF6WTk7c0LNuAYgLXab-vWeIB6bWwiT9fRqwsT_5vi825A-narKNUaE7ICdja2FAYqdOu_WNzZ9qpIEdefYTowiIVAlSg52BGm6IgUUbMF_XnlojGIIbZ7bSfiu6z2C28FpBk8tZjv37mosm7Yw=w1377-h918-no?authuser=0 People enjoy th...

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...

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...

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...

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...

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...
