Further east still, the lion’s tail is marked by second magnitude Denebola (Beta (β) Leonis). Follow the direction the tail is pointing to a region of sky known as the Realm of Galaxies. Sitting just to the north of another large asterism, known as the Bowl of Virgo, the realm is...
as such, form part of the Hubble sequence. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge.
That is all true. The point here is that unless your subexposures are limited by the read noise* you will get the same end result without the reducer by exposing just as long (total exposure time) and then downscaling the image in post to match. Using a reducer is a way of ma...

Yes, the 7x50SP is also known as the 7x50 Prostar, and has the red line on the front objectives. Mine, new, came with hard plastic eye guards which I detached and then replaced with the soft rubber eye guards similar for instance to the ones on many other individual focus binoculars...

My first two date back to either the late 1960's or early 70's; and I don't recall which is the older observation. My records from that point in time no longer exist. 1) I had taken a long (as in 5 miles or so) walk on a nice summer day and decided to take a rest in a...
4. The LX90 is known for good pointing accuracy. It has not been established that your issue is not something simple, like asking it to perform at a level of accuracy that is beyond it. For example, looking for M51 in a 10 mm eyepiece--you might be very much in the neighborhood, ...
