How to Use a Red-dot Finder Scope for Astronomy

Posted by Ryan DeLange on

If you’re having a hard time getting anything to show up in your telescope’s eyepiece, then you probably just need to learn to align and use your red-dot finder scope. Most new astronomers go through this frustration. Don’t worry, this guide will give you the know-how, and with a little practice, you’ll get the hang of it. First off, let’s take a look at the instrument. A red dot finder scope has no magnification power. It simply transposes a tiny red dot onto the image you see when you look through the finder scope. Many red dot finders come with...

How to Choose a Telescope for a Child

Apart from the romantic aspects of owning a telescope (the mysteries of the universe and our place in it), there are practical benefits for children too: increased scientific curiosity, hands-on experience with the principles of physics, a sense of reward for patience, study, and action. What a great gift that a child can experience - all without leaving the backyard! This guide will help you choose the right telescope for a child. Let’s explore what type of telescope is the best gift for your situation. You might first want to read this in-depth article about the types of telescopes. Telescope...

Nice Apo and a Real Value

I bought this scope for an industrial client whose needs are industrial, not astronomical, and this Explore Scientific ED127 is intended to be a beam expander in various Interferometric testing setups. For this, optical quality must be high and the carbon fiber tube is a plus for thermal stability. My purchase of the Explore Scientific ED127 F7.5 APO Triplet through Telescope Space was straightforward and pleasant. Ryan made sure everything was smooth.
Upon receipt I tested the scope by looking at a power pole 700 feet away, one that I have used for many such tests. The star test from the insulator glints was good – the focus snap was crisp, the in-focus diffraction blur was round with a faint first ring. I did not look at the through focus balance with a narrow passband filter as it was obvious there was no SA3. Color correction is very good as you would expect with the glasses used. There is no color in focus, and only a hint of subtle color fringing in the just out of focus edges of details. Extended details on the pole were rendered as well as, or better than, with any similar scope I have used on this target – this includes TMB, Astrophysics, and Takahashi scopes.
The build quality of the carbon parts is gorgeous. The metal parts are good quality anodized machined. I would prefer machined tube rings as the cast ones supplied are a little chintzy compared to the rest of the scope. The rack and pinion focuser works well, but the feel is not as good as some stock friction focusers I’ve used. Considering the extra high weight capacity of the focuser the feel may be the price paid. Overall I think the mechanical appearance and function is in line with the price.
I would certainly consider the Explore Scientific ED APO FCD100 triplet scopes for my personal use. My transaction with Telescope Space was great and I will do business with them again.

Review on Firstlight AR 102mm f9.8 on EXOS NANO EQ3

A great package for the price! The mount is steady! The Optics excel, in that the resolution and contrast are everything to be expected in a quality refractor! H.B. Appleton, Hi.

The staff at Telescope Space were very supportive and helpful as well!

Explore Scientific Mak Cas 152 with EXOS2GT MOUNT

I did considerable shopping around and finally decided to buy my 152 Mak from Telescope Space. Ryan was very helpful with all my questions concerning Explore Scientific and my specific purchase. After a short period using my scope and mount, the mount seemed to have more play than it should have. Ryan had the Explore Scientific owner call me directly, where he immediately offered to exchange my mount. He also had the factory ship out the new mount while I was still using my original unit. Excellent service and sales support from both Ryan at Telescope Space and Explore Scientific. I will buy again from Telescope Space!

Very clear, I am impressed for $38
