The Leo Triplet is a popular trio of galaxies in the constellation of Leo, popular with amateur and professional astronomers alike. They are visible in the late winter and spring in the Northern Hemisphere. Consisting of M65, M66 and NGC 3628, the galaxies are about 35 million light years away. NGC 3628 was never given the distinction of as Messier number for some reason, even though it is as bright as the other two members. The image was taken with my Samyang 135mm DLSR lens coupled with Moravian G2-8300 cooled CCD camera with Astrodon RGB filters. It consists of seventy minutes (5 minute exposures binned 1×1) in each of the red, green and blue filters to give a total integration time of three hours and thirty minutes. The triplet was about 45 degrees above the horizon when the exposures were captured. IT was then processed with Pixinsight and Photoshop. The…

In order to get the best from your observing and imaging sessions, your reflecting telescope needs to be properly collimated. In other words, the optical axis of the telescope must be optimised to reflect the light optimally. Newtonian and Ritchey- Chretien design scopes do not deliver a crisp and sharp image unless they are properly collimated. A laser collimator is a device that can aid in getting the telescope properly collimated. I want to emphasise that I am not in any way paid in money or kind to write these words. I do this for the love of it and to help others and I have no connection whatsoever to the maker of these collimators. Sadly, Howie Glatter himself passed away in 2016. He was a very kind man and was incredibly friendly, knowledgable and approachable. There was almost nothing he didn’t know regarding the subject of collimation of telescopes! …
