The California Nebula (NGC 1499) is an emission #nebulae in Perseus, glowing about 1,000 light-years from Earth and stretching nearly 100 light-years across. Its deep red light comes from ionized hydrogen, excited by the nearby hot star Xi Persei, which floods the nebula with ultraviolet radiation.

Team work in #astrophotography 🔭📷 gives nice results. Here is M33, a neighboring galaxy combining images from 3 setups. I'm always amazed with its bright blue stars that can be resolved from several million light years away.

I tracked this dramatic area in 'Orion's Belt' for nearly 8 hours to capture the light for this photo.

What's cool about #astrophotography 🔭📷 is that you can stack frames to create nice images, and also use those frames to do some aperture photometry (here with AIJ on the eclipsing binary V1337 CAS near IC1805 Heart Nebula AIJ). Ain't that cool people 🤓?

Solar #astrophotography 🔭📷 does have its perks...like getting your images taken in 10 minutes between two rainy episodes.
This is the Sun as it was late this afternoon in France, shot with my Lunt 60 and my ASI1600GT mono camera and dodging quite a few clouds and rainy spells.

This was shot on the EdgeHD 8 with Hyperstar for a total integration time of 7 hours in OSC and Mono. I used the mono Ha data to enhance the red and the luminance details.
