I recently found a smoking deal on a telescope I have been considering for a while, so I jumped on it an I’m now the proud owner of a nearly new Astro-Tech 8”, f/8 Richey-Cretien telescope. It took a little work to get the collimation (alignment of the mirrors) right, but I’m now very pleased with the results. As a test I decided to re-shoot the Bubble Nebula to compare results. This new telescope has a much longer focal length (1625mm vs 563mm with the other scope) which gives me a much smaller field a view to go after smaller objects like distant galaxies. So far, I’m pleased with the results…I hope you are too!
