Light Pollution Filters

This Link appears to be, the only place where the Ice Lipo filter is tested & discussed.
I use it myself.

Some notes from back in 2011:
First visual observing session - 3/10/11 Using Barska 15x70 binocs on low-cost tripod.
Observed Globular star clusters M13 and M92. The Hercules Cluster was pretty easy (of course). M92 was very faint, however.

Old film photo - Corona Borealis

Recently found an old film AP pic I took. I'm afraid I don't have a lot of info on this one.
I can tell you it was taken years ago, using Kodak ISO 200 Slide Film, and scanned with an Epson scanner. It may have been taken with a Pentacon Six, Medium Format camera, but again, I'm not sure. I had to significantly reduce it, just to upload it. Orig. size was over 96MB!
Just a random shot of the area near the constellation Corona Borealis (seen on the left-hand-side of the pic).

Tried Film Astrophotography again...

I tried tripod-mounted film Astrophotography again...Yes, a bit of Déjà vu here. I basically only ended up exposing ~1 roll of film per camera. And, for some cameras; I didn't even get to shoot any film - That's how fast I changed my mind, and started listing them on e-bay. I hope to post some of the results soon...
I believe I've only got about a handful of "viable" prints to show for it -For the whole ordeal, and all the inconvenience, etc.

Well, this was my 2nd (low-budget) film camera collection, when it was at about it's "peak"
Just before everything was sold (on e-bay):

I did have a Petri 1.9 in pristine condition (not pictured) - And, I didn't get a chance to even shoot one roll of film through it.


Insanity: doing the same thing over and over again and expecting different results.

Some "Quick & Dirty" Book reviews

It's been quite a few years since I sold all my Astronomy books. There were some good ones in my collection. I've always especially loved books by Philip Harrington
(http://www.philharrington.net/). In fact, I still have (and read) the 1st Edition of his Star Ware.

Well, I've been reading a lot lately... Since I've become very interested in Visual Astronomy again, I've bought several books. And, I thought I'd list them here, and give my quick impressions of each.

Visual Astronomy in the Suburbs: A Guide to Spectacular Viewing (Patrick Moore's Practical Astronomy Series)[Paperback]: Excellent, highly recommended. I love this one. I also like the fact that the subject of Image Intensifiers. The subject is new to me, and really interesting. Even though I have owned and used a Meade CCD camera before.

Binocular Astronomy (Patrick Moore's Practical Astronomy Series) [Paperback]Stephen Tonkin (Author):
Awesome, just as good (maybe better) than the book above! Just great - A wealth of information.

Real Astronomy with Small Telescopes: Step-by-Step Activities for Discovery (Patrick Moore's Practical Astronomy Series) [Paperback]
Michael Gainer (Author):
Not a bad book, but not fantastic either. Honestly, I was a bit disappointed with this one.
While reading this book, I get the feeling of actually being discouraged from attempting any visual observing. The Author seems to dwell on the negative side of observing from light-polluted areas.

The Urban Astronomer's Guide: A Walking Tour of the Cosmos for City Sky Watchers (Patrick Moore's Practical Astronomy Series) [Paperback]Rod Mollise(Author):

I loved this book! I actually haven't finished reading it all yet. But, I can highly recommend it. It is the exact opposite of the book reviewed above ^ This book is simply excellent! I give it an A+

Well, that's it for now. More book reviews will follow, at some point in the future...

One of several old Barn Door Trackers...

Here are some old pics I came across, of one of the Barn Door Trackers I had.
I tried to get it to work...but literally blew out transistors on the circuit board because the camera was too heavy. I went through two Stepper Motor controller boards, before I gave up and sold it.
