From my series 'tiny deep-sky objects shot with the Samyang 135mm f/2' comes the newest entry M52 and NGC7635, better known as the Bubble Nebula! These two objects were part of my Cepheus mosaic. I performed a separate stack, using 2x drizzle, to prepare a view on those two. I never thought I would be able to resolve the bubble, but it worked! :)
