NGC 2024 – Flame Nebula

28 August 2021

Emission nebula in the constellation Orion. It’s around 1,500 ly away from Earth. The shape looks like a fired flame or a torch with an angular diameter of about 0.5 °, visible in the sky near the star Alnitak. The Flame Nebula has a reddish hue in visible light, which is due to the glow of hydrogen atoms at the ends of the giant Orion Molecular Cloud about 1,500 light-years from Earth. Ionized hydrogen atoms glow, during the recombination process (recombination of electrons and atomic nuclei).

NGC 2023 – Emission and Reflection Nebula

23 August 2021

The diameter is 4 light years. It surrounds the young massive star HD 37903 of spectral type B2 Ve. The energy of this star illuminates the nebula of molecular hydrogen, which emits near-infrared wavelengths and relatively high surface brightness. New stars are forming in the material from which the NGC 2023 nebula was formed. The gas waves surrounding the star are 5,000 times denser than the interstellar medium. The shock waves stimulate the gas to glow, creating unpredictable forms observed in the nebula.

SynScan GOTO v4 controller – trouble with buttons

At some point while using the controller, I noticed that the ESC button wasn’t always working. I lived with it, but after a while, the left Ra button also started acting up and wouldn’t always connect. A red flag went up in my head – something needed to be done. It’s worth noting that the problems appeared right after the warranty period ended… coincidence?

EQDIRect - self made - in use

EQDIRect for NEQ / EQ mounts

The GOTO controller is extremely convenient and practical to use, when you want to look at interesting night sky objects, with your own eye through the eyepiece mounted in the telescope’s focuser. The ability to quickly select an object using the GOTO controller, is invaluable.
