If you own a Celestron SkyProdigy 6″ SCT telescope, you can fit the Celestron #93781 9×50 erect image angled finderscope to the OTA (optical tube assembly)
The only additional items you need to purchase are longer screws to make it fit properly. The screw size is M4 x 12mm
The Celestron 9×50 illuminated finderscope is optically superb. Good enough to be a fantastic wide field scope on its own

For modern Sony Alpha DSLRs the correct t-ring is the Sony Alpha or Minolta Maxx. These simply attach between the camera body and the telescope / adapter / barlow lens with standard t-thread.
Note that with Sony alpha cameras you will need to use manual exposure
Sony Alpha and many other t-rings can be purchased from Northern Optics
The Visionary T-15 (15×50) monocular is designed for long distance terrestrial use, Plane spotting or ship spotting. Superb fully multi-coated optics with BaK-4 prisms give a very bright and clear image , despite the small exit pupil.
Tough rubber body and nitrogen waterproof for use in all conditions. The eye cup does not twist out with this version due to shorter eye relief. But on testing, I found I could get a full view with glass on.
Comes complete with a carry case and lens cover (main objective only)
The East Midlands Stargazers is a friendly forum for astronomers. Whether you are a beginner or seasoned pro , there will be a section for you. It is not just for astronomy. There are sections where you can discuss off topic subjects on anything you want.
Many on the forum are based in Lincolnshire, where most of them chose to buy from, and support their local telescope dealer Northern Optics
A star diagonal is not recommended for use on a Newtonian reflector telescope. This is simply because there may not be enough inward travel to get infinity focus. You may be able to get around this by using a low profile focuser, or moving the primary mirror up the OTA (optical tube assembly)

So what is the difference between the Ostara Moon & Skyglow filter and the similar priced Crystalview Moon filter ?
The Moon / Skyglow is more of a dual use filter. It cuts down on light reaching the eye, for more comfortable views of the Moon. On top of this, it also helps reduce sodium light (street lights) to aid deep space views. However this does mean you get a bluish tint.
On the other hand, the Ostara CrystalView Moon filter does not act like a light pollution filter . It is more a dedicated Moon filter. For the Lunar observer the advantage of this filter is that it gives a more neutral colour.
So that is the differences between the two filters. If looking for a dual use filter, go for the Moon / Skyglow. Or if you are a dedicated Lunar observer, go for the CrystalView. But there is no harm in having one of each.
Each one comes in its own padded , hard plastic case
Both filters can be purchased from Northern Optics
The Skywatcher extension tube fits direct on to an EQ5 or HEQ5 mount for use with refractor telescopes. The EQ5/HEQ5 extension tube extends the height of the EQ5 and HEQ5 mount so it is easier for observer to look into a long refractor. Installed between the tripod and the mount head, this heavy-duty metal tube adds about 16″ in height to the assembly while maintaining the stability of the mount.

The North Lincs astronomy society met at Ness End reserve near Barton Upon Humber on the 3rd January 2013.
The highlight of the night was a talk by Paul Cotton on astro photography. This was aimed at all members from beginners to advanced. Tips on how to set up your telescope, stack images and do some editing was very educating. As a result, we all went away feeling inspired, and had a go at astrophotography ourselves
Sadly, the night sky was not playing ball, so we could not practice our new skills that evening
Present, as always was Northern Optics of Lincolnshire. As always they had a selection of telescope accessories and binoculars for the members to purchase on the night. Northern Optics also donated the raffle prise of a Helios pair of binoculars
Thank you as always to Sarah for the refreshments and the Lincolnshire Wildlife trust for the use of the venue
