Key Takeaways The Askar SQA55 uses high-quality optics to produce astrophotography images that are sharp, flat, and well-corrected. It features an innovative design with a variable aperture, similar to a camera lens with a manual focus ring. The small aperture (55mm) and short focal length (264mm) mean it is unsuitable for planetary imaging or photographing... […]

My own Hubble View! These galaxies lie between 10 to 50 million light years away. How many galaxies do you see? A pretty tricky part of the sky to image, really. You're utilizing almost your entire field of view with an 80mm scope, so dealing with all that comes with wide-field. This is the best […]

It lies around 23 million light years away and it is interacting with a smaller galaxy (yellow~ish bulge to the left). Three supernova (star explosions) have been detected in this galaxy […]
