IC1848 - The Soul Nebula. I am officially blown away by the detail in my first real SHO image. This is just 30 mins on each filter. I can't wait to see the results when I get several hours on it. ASI2600 MM, Esprit 100ED, Altair 3nm Ha, Sii and Oiii filters. #astronomy #astrophotography

The Soul Nebula in Ha. This is 30 mins in Ha from the only clear spell since my mono set up arrived. The signal is so much stronger than with my one shot colour camera. I guess 30 mins in mono is equivalent 120 mins with OSC Can't wait to get the Sii and Oiii. #astronomy #astrophotgraphy
