Binoviewer Review

26th Oct, 2007

Binoviewers and caseLast week I was lucky enough to be able to borrow some binoviewers for a weeks use, from James at ScopesNSkies. I was very dubious that a pair of binoviewers could really give me a better view or increased viewing pleasure.

The binoviewers are just like a pair of binoculars that can be attached to the telescope. The main advantage of buying and using a binoviewer is that you can keep both eyes open whilst viewing and it seems as if we are more used to using binoculars than we are at viewing with just one eye.

Binoviewers from behindThe major disadvantage of the binoviewers is that you will have to buy two of every eyepiece, so increasing your costs.

On the other hand I can also see that the binoviewers are a brilliant idea if you have group observing sessions, such as when you want to have your family around to have a night observing with them, as I know the viewing will be greatly enhanced by the binoviewers as I am sure most people have used binoculars before and are used to using them.

BinoviewersThe eyepieces are held in place by a really nice half turn fixing, and the binoviewers are really well made and also quite heavy, I did find that the heavy weight was sometimes a problem when trying to secure the binoviewers into the diagonal when I wanted a really nice angular viewing angle.

The binoviewers took a while to get used to, as I was under the impression that you could put an eyepiece in and use it to get focus then take out the eyepiece and put it with your other matching eyepiece into the binoviewer and keep focus, but you can’t as the focus point has then changed.

Binoviewers with eyepieces insertedAfter a while of getting used to them I was amazed at how much extra you could see, or you thought you were seeing! Your field of view is very large when using the binoviewer as you are now using two eyes. The binoviewers are also very comfortable to use with some nice eye relief provided by your eyepieces.

The thing I was most impressed with was that I actually felt that what I was seeing was actually kind of 3D instead of a flat field kind of view you get with a single eyepiece. You do actually become more immersed into what you are looking at as well.

Binoviewers attached to LX200The binoviewers cost around £120, so are not a cheap purchase, although they do come with a set of eyepieces included. I think they are a bit of an extravagance but something that you may find will give you pleasing and improved viewing sessions.

With a number of clear nights in a row last week I managed to stay out for a number of hours and actually get used to using the LX200. I also managed to let the LX200 take me on some of the tours I uploaded from the Meade website.

Whilst out I managed to get some photographs using prime focus as well as using my camera bracket on top of my LX200 to get some shots with my Canon 75-300mm lens.

This shot of the ring nebula is a bit blurry, as it needed a lot of exposure time as without it I just could not gather enough light.

I was quite amazed to find out that Meade still only allow you one way to connect your telescope to your PC, which is via an RS232 cable / 9 pin cable, the other end plugs into the RS232 slot on the LX200 base.

I would have thought by now that Meade may have added Firewire or USB to the LX200 range, but I must admit that RS232 is such a well known standard that it could be used for a while yet.

The only problem with serial connections on a PC is that some newer PC Desktops don’t have serial connections on their motherboards anymore, as I found out when I built my own new Core Duo PC earlier this year. Although most people probably don’t use a desktop PC with their Meade Telescopes unless they have PCs in their observatories, they would probably instead have a laptop. Another problem is that most newer laptops also don’t have serial connections, it seems now that the newer the laptop the less ports it actually has.

USB to RS232 Serial CableSo what can you do? Well you’ll probably need a USB to Serial cable or adaptor. I went for the cable and purchased it on eBay. Once I had received the cable from Hong Kong which cost me about £4 including delivery I had to install the drivers. I found that the accompanying mini CD would not actually be read by my laptop cd drive, so I hunted around the internet for drivers, and I tried absoultely loads, but none of them worked, in the end I put the mini CD in my desktop PC and it read the disc ok.

But because some people may not have more than one PC I shall place the driver I used on this page in case I or anyone else needs it in the future.

The CD that came with the adaptor contained many different adaptors, but luckily the code of the driver folder required is actually the name on the adaptor cable at the serial end on the plastic sleeve.

Setting up your PC and Meade Software

Then just connect the cable you purchased to the supplied Meade LX200 cable and adaptor.

The Serial connection defaulted to COM Port 5, although the Meade software only really gives you the choices of COM1 - COM4, so I changed the COM port of the cable on the PC in properties of the cable to COM1 for ease of use.

Make sure that your PC COM port is set to the same as the Meade software Com port in order to get the telescope to talk to the PC.

The first thing I did once I got the PC drivers installed was to update the Autostar software to 4.2g and to upload the latest autostar tours, comets, asteroids and satellites. All of which were easy to install via the Meade control panel on the PC.

I finished off by updating my Autostar Update (AUS) Client Application Software to Version 4.6 on my PC, but you don’t need a usb to serial cable to do this.

Moon Observers GuideAs you would expect the Moon Observer’s Guide (ISBN 0540084190) is a book all about our moon and a what a complete book it is. I think it must contain everything you ever need to know about the moon.

Moon Observers Guide contains chapters on lunar geology, the moon in space, lunar observer’s equipment, moon watching, recording your observations, eclipses and occultations, and the space-age moon.

The Moon Observers Guide contains a useful chapter which discusses the various type of telescopes you can use to view the moon and their advantages and disadvantages.

Throughout The Moon Observer’s Guide are some nice colour and black and white images and drawings of the moon.

A large section of the book follows the moon cycle through 28 days with each day containing a page about the part of the moon that is on show together with an image of that new section on show naming each section of the moon. This is just like having a moon map but split into days which is really good.

There are also chapters on how to record your observations using conventional photography, and digital photography including using camcorders, web cams and digital cameras. Finally there is a nice chapter describing occultations and lunar eclipses.

Overall this Philips title is really good and can be purchased on its own or within the Moonwatch pack which also includes a moon map and moon poster.

Philip’s Moon Observers Guide is available from Amazon

Daytime Moon

4th Oct, 2007

Whilst out in the garden at lunchtime I was amazed to see the moon at around 2pm in the western sky today, not something I get to see often, so I had to go and get my tripod, remote and 300mm lens out and here is what I took.

Philips Complete Guide To StargazingThe Complete Guide to Stargazing (0540089370) is an amazing astronomy book from Philips, which is more like an encyclopedia of astronomy, it’s certainly a coffee table kind of book which you could leave out and see lots of friends pick up and flick through.

The Complete Guide to Stargazing is a very large full colour astronomy book which contains hundreds of images both from NASA and from amateur astronomers alike.

The book was first published in 2006, but this review is based on the reprinted 2007 edition.

The Complete Guide to Stargazing contains eight chapters with a very large a-z of astronomy at the rear. The first chapter entitled ‘The night sky’ introduces you to the basics of the sky including details on wavelengths, distances of galaxies, about stars and how we view them.

The second chapter entitled ‘Getting Started’ introduces you to the night’s sky and how it moves, as well as the sun’s movement, scale of the sky and star brightness.

The third chapter is about equipment for observing, and discusses using binoculars for astronomy as well as teaching you about the various types of telescopes, mounts and how to get to know and use your telescope.

The fourth chapter is about our moon, and contains some great photos in it of the moon and the lunar landings. There are also useful moon maps included.

The fifth chapter is about the solar system and includes information on how to view the sun through a telescope via projection or by using solar filters. Many full colour images of each planet in turn are shown throughout the chapter including images from a distance and terrain images where available, and it’s nice to see amateur images making it into the book, some also detail what type of telescope took the image.

Chapter six covers stars and deep sky objects, again this chapter includes some brilliant images and tips on how to draw objects and photograph them.

Chapter seven is a very useful chapter covering the sky month by month with sky maps and images as well as full descriptions about each item.

The final chapter contains sky maps, and they have been laid out very well, as the left hand side of the page is a map page indicating the constellations and stars, whilst the right hand side of the page is a matching image of the real sky. This makes it really easy to learn the night sky.

Overall The Complete Guide to Stargazing is an amazing book with amazing images, a book which I’m sure most astronomers would love to have, and I can imagine this book being a great gift for anyone interested in astronomy at any age.

The Complete Guide to Stargazing is available at Amazon now.
