Top 10 Telescope Filters for Better Observing

Color FiltersMost of the time, we want an uninterrupted light path and perfectly clear optics for viewing the night time sky.  It may surprise you to learn that putting something in the path to decrease the light actually improves the view, but it’s true.  Below are descriptions of the top filters that can improve your observing.  Bonus description of a few more to make it a Baker's Dozen, describing nearly every type of filter used most often by amateur astronomers. 

Astronomy Tips, Do's and Don'ts for Beginners

Many people just starting out with astronomy could use a few tips to shorten the learning curve and reduce the challenges of a new hobby.  Skills increase faster with a few basics in your toolkit.  Here’s a handful to get you started.

Taking Good Observation Notes

Beautiful M51, the Whirlpool GalaxyMaking observational notes is key to remembering what you have observed.  Looking back at my early logs, I saw a clear pattern.  Everything was "beautiful", "brilliant" or "striking".  I needed a thesaurus when I went observing to keep myself from being repetitive.  I noticed I could not tell you much about any of the objects I observed.  My descriptions were too vague and tedious...

I decided to learn how to describe what I was seeing more clearly.  By taking notes that were based primarily on objective parameters, I've become a better observer.  I notice the details that previously were lost in the awe.  Since learning the skills of taking better astronomy notes, I can tell you why and how those objects are "beautiful", "brilliant" and "striking".  This document can help you improve your observation logs and take your skills to the next level.

Find Objects by Star Hopping

Globular Cluster M14 (NGC 6402) in the constellation Ophiuchus It's not hard to find the Orion Nebula or the Pleiades with your binoculars because they are bright enough to see without magnification.  Look straight at them without help, then put your binoculars in front of your eyes.  With just a little practice, the object will appear in the binocular view the same as naked-eye, only bigger.

On the other hand, finding objects too dim to see naked-eye is challenging to most new observers.  How do you find something that is too dim to see without magnification?  The easy answer is to point at the bright star right next to it and hope you can see the dim object too.  But what if it is not right next to a bright star?

The trick is "Star Hopping".  This article will teach you how to hop from bright naked-eye objects right to the dim objects you're wanting to find.  We'll use a technique practiced by experienced amateur astronomers for generations.
