M46 M47 and NGC2438

Open star clusters M46 (NGC2437) with Planetary Nebula NGC2438 and M47 (NGC2422/2478) are located in constellation Puppis.

Setting : ASI2600MC with TLAPO80/480 f/6; ZWO Guidescope 30/120 and ASI224MC

Lights : 2x90s 5x300s

Software: N.I.N.A, Stellarium, PHD2, APP, CS4

Orion M42 - OIII and ASI2600MC

Past weekend I took the time to optimize my PHD2 guiding skills. The build-in "Guiding Assistance" was used and the camera exposure time was increased from 1s to 2s. The guide pulses in EQMOD are increased from 0.5 to 0.9.

I made sure the 2" flattener was set at exactly 105mm till the + 17mm ASI2600MC chip. 

Setting scope : ASI2600MC and TLAPO80/480 f/6

Guiding : ZWO Guiding scope 30/120 and ASI224MC

Globe at Night - Saving Private Orion

Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. Past weekend I submitted my backyard data (ID #95057) after observing constellation Orion with a max magnitude of 5.5.

Asteroid (16) Psyche

Last thursday (March 3) asteroid (or better planetoid) Psyche was in opposition. Psyche is a giant iron-nickel metal-rich M-Type asteroid, about three times farther away from the Sun than is the Earth. Its average diameter is about 226 km.

Psyche might be the partial core of a shattered planetesimal – a small world the size of a city or small country that is the first building block of a planet. If it is, asteroid Psyche can offer a close look at the interior of terrestrial planets like Earth that is normally hidden beneath layers of mantle and crust. Therefor NASA is planning for a mission, NASA's Psyche Mission which is foreseen to be launched with a Falcon Heavy rocket from Launch Complex 39A at Cape Canaveral Air Force Station in Florida. Milestones:

2022 – Launch of Psyche spacecraft from Kennedy Space Center, Florida

2023 – Mars Flyby of Psyche spacecraft

2026 – Psyche spacecraft arrives in asteroid’s orbit

2026-2027 – Psyche spacecraft orbits the Psyche asteroid

Psyche is currently visible in constellation Leo and about magnitude 10.4. I was able to take some pictures on both march 4 and 5. Psyche could be observed near galaxy NGC 3462. Below is a gif picture with a time interval of 50 minutes.
