The Dark Shark Nebula: A Glimpse into Cosmic Depths with the Askar 91F
This week, we're diving deep into the cosmos with a truly spectacular image captured by our fellow space enthusiast: the Dark Shark Nebula, also known catalog-wise as LDN 1235.
This breathtaking vista is the result of approximately two weeks of dedicated work with the Askar 91F telescope. What's even more remarkable is that this particular image is the product of just 82 minutes of data acquisition, taken from a Bortle 3 location – a testament to the power and efficiency of modern astrophotography equipment.
