Here's the WEATHER UPDATE for tonight's Sidewalk Astronomy at Riverview High.

It's a frustrating forecast to say the least. 🤔

I've checked half a dozen sources and there is no consensus. Some are predicting scattered showers ending by the time we're ready to set up; others are calling for rain potentially all evening... and still others are showing clearing skies after about 7 PM.

So for the moment, Sidewalk Astronomy is still a "go," but be aware that there's a possibility that we might have weather issues during the evening that could bring an abrupt end to the observing.

Used eyepiece case (purchased from Orion)


Pickup only in Ellenton, Florida—will *not* ship or deliver (unless it’s to an LGDSO event that we’ll both be at)

Case measures 18” x 13” x 6” (O.D.)

Note that the “pick-and-pluck” foam is already picked and plucked.


Drop me a line at, or call me at 941-518-8695 if interested.

I have been bantering with this seller about a day or so now. While his pictures don't show it, he does have the Computer Intelliscope Hand control. He is about 40 miles north of us just east of Brandon. This is a big scope with the OTA alone at 50lbs.
So its either a jewel or junk but at ($650 minus your best negotiating skills) I think it might be a good buy, especially if you flash cash. Over $1000 new, plus it appears he has a custom case. And eyepieces too.

I do not know this person.  I like to see and try things I buy and this gives you a chance if your looking for a big dob. Look at the mirrors for cracks and missing coatings. And make sure the computer "push to" component works.

Interesting that the placement of the barlow can add 3x if placed before the diagonal. Ya learn something new every day.

Here's a couple more short videos that you might find interesting and helpful:

The first describes the benefits of various types of visual filters:

The second talks about the purpose of a Barlow Lens:

Clear Skies!!!
In my many years of working with those new to telescopes, 2 things come up time and time again.

1. How powerful is it (aka magnification)? Often, in fact most times, "less is more".

2. The finderscope. It can be your best friend if aligned or your worst enemy if not aligned.

I found a couple of short but very helpful videos for those of you out there who have struggled with this:

Magnification -

Finderscope -

Hope this helps!!!
