Visual Astronomy Buyer Guide – Introduction

Most newcomers to Astronomy start with the quintessential telescope.  These telescopes are widely available and offer an easy entry into the hobby. Notes:   Keep your expectation real.  No telescope is going to provide a view akin to a Hubble image.  Making visual observations require some patience and appreciating nuance. What to Avoid:  If you want to view deep sky objects, avoid telescopes with an aperture smaller than 6″.  A telescope is a light collector – and more light means faint…

Where to Stargaze Around Raleigh and Beyond

Local Places (and beyond) to Skywatch at Night RAC’s home area includes Raleigh, Apex, Cary, Garner, Holly Springs, Fayetteville and surrounding communities. Looking for a good observing site can be challenging.  The Raleigh area is beautiful during the day – lots of trees, great public parks, and convenient shopping centers.   However, at night parks close and light pollution obscures the night sky. What do you want to Observe To find an appropriate spot to skywatch, what you plan to observe…

Guide Scope Pixel Scale

When setting up a guide scope, the main consideration is the comparison of the pixel scale of your imaging rig compared to your guiding rig. Pixel ScaleThe pixel scale is just 206 * (pixel size) / (focal length). Assuming your 30 mm guide scope is f/4 that would be a focal length of 120mm.  Using a common guide camera such as the ASI120MM which has a pixel size of 3.8u, the pixel scale is 206 * 3.8 / 130 =…

Recommended Dobsonian Telescopes

RAC receives a lot of questions about buying a telescope. The answer always depends on your goals in astronomy, but for many a dobsonian style telescope is the most cost effective option to own an amateur class telescope. Dobsonians are relatively inexpensive because their optical tube is the least complex and it is mounted on a very simple base. This makes them very rugged telescopes and very easy to set up and operate. And since Aperture is king when it…

Telescope Accessories

No telescope comes with all the accessories you need out of the box. Consider this list of accessories that many amateur astronomers buy over time. The exact accessory may depend on the telescope you buy. What not to Buy Generally you’ll get a 10mm and a 25mm plossl eyepiece that fits a 1.25″ focuser. Stick with those. They’re all you’re going to need for a while. Avoid buying color filters as they are virtually useless. Also avoid buying any 1.5x,…

Aperture is king

For visual astronomy (looking through the eyepiece at the telescope), aperture is the most important feature of a telescope. Telescopes are light concentrators, so a bigger aperture collects more light and dim objects are brighter. Magnification is not an important consideration for most first-time telescope buyers. For most newcomers to the hobby, it is recommended to start with at least 1200mm of focal length and at least a 6″ mirror. For every 2″ of aperture you add ~72% more light…

Tips for Photographing the Comet

By: David KellerFor those of you that want to try your luck at photographing comet NeoWise, and are not experienced astro-imagers, here are some suggestions:   Equipment:    Tripod:  You absolutely require a tripod or an equivalent way to hold the camera still, and that’s because to get a decent photograph, you will need an exposure in the range of 2-6 seconds.  If you’re using a smartphone, many inexpensive camera holders are available on Amazon.  If you’ve a DSLR (or…

Neowise from Jordan Lake Dam By: Joe Pedit

The clouds broke a bit before 5 AM this morning so I was able to grab a few shots of Comet Neowise from the Jordan Lake dam.  I will probably go back Friday morning.  It is possible to image the comet from the parking lot so I will be setting up my telescope there instead of carrying it 200 yards onto the dam.  The only issue may be fog from the tailrace, but flow is low so mist production is…
