A canon EOS 1100D (un-modded) was used to take this image of the summer triangle, that includes the 3 bright stars Vega, Deneb and Altair in the constellations of Lyra, Cygnus and Aquila.
This image was taken in heavily light polluted skies. Equipment used – Canon EOS 1100D on a Skywatcher HEQ5 mount. Settings 30 seconds exposure at 3200 ISO. A single RAW file image was used. Camera was set at 18mm at f5.6
A light pollution filter was used. For this I used a Ostara 2 inch Moon / Skyglow filter . So how did I connect a telescope eyepiece filter to a DSLR camera lens ? . I simply rested it on it
Processing was done using Canons Digital photo professional. Using the histogram to bring out more detail and fainter stars also increased the orange sky glow. To remove this, I simply decreased the red in DPP. This reduced colour from the stars, but made the image much better due to the reduced light pollution. There are still some remnants of this on the image as you can see though. But considering the heavy light pollution, I think you will agree it is a good image that also shows the milky way
At the weekend a customer visited the Northern Optics outlet at the Waters` Edge centre , Barton Upon Humber looking for a quality spotting scope for looking at ships and boats out at sea or mainland rivers.
After sampling a couple in his price range, he opted for the Celestron Ultima 80mm angled spotting scope. Even though it is not rubber armoured like the other brand he tried, he was instantly impressed with the bright image and the fact “It looked good”. Which proves that even though the ultima range are a few years old, they still perform great and look the part compared with many modern designs.
The Ultima 80/45 comes with a standard 20-60x zoom, but can be upgraded to fixed eyepieces in the 19x – 80x range. There is a 100x option, but I believe this is pushing the power to far

When you look through your astronomical telescope at the night sky, telescope filters will help you see more detail. Filters come in many varieties to enhance viewing from light reduction, light pollution filters to different colours and ones that only allow certain wavelengths through to the eye . Some are for visual and others for imaging (or both).
All filters screw in to the eyepiece and generally come in 1.25″ or 2″ sizes
The latest Opticron DBA VHD 8×42 and 10×42 binoculars offer high end ED glass with phase corrected BaK-4 prisms for outstanding clarity. The dual hinge body is lightweight at around 700g for great portability.
The long 17-22mm eye relief means they are ideal for spectacle wearers. Nitrogen gas filled for use in all conditions.
A field of 105m – 122m is not as wide as some. But what you do get is a flat field, that does let some wide angle binoculars down on edge of field quality
Perfect for birdwatching or general use
The Olivon PC 8×42 binoculars were the optics of choice at the Waters` Edge centre public outlet for a customer looking for a high quality set for general use.
After trying a few sets, they opted for the Olivon PC 10×42 binoculars. As always when a customer tries a number of sets, after we have give initial advice, we take a step back and let the buyer chose with no outside pressure. We do this for two reasons, (1-) No customer likes a sales man breathing down their neck,(2- ). What suits me, does not mean they suit the next person that comes along.
Back on to the binoculars, the customer immediately found compared to lesser priced binoculars, the phase coated prisms gave a edge on sharpness. Also they commented on the build quality. For this reason the Olivon PC 42mm binoculars are one of our best sellers

We had the first chance to give the new Helios Lightwing 8×32 binoculars a test this week. As always the first thing you see, or should I say feel is the build quality. Although they are compact in size, they feel very solid in construction. This gives you reassurance these are built to last.
The twist eye cups move smoothly out for users without spectacles on. The cups are a very sleek and attractive design, and not chunky like many others. The focus is also extremely smooth to use, similar to the Mistral series.
Considering these are not ED glass, the quality and brightness of the image is exceptional. Phase and Silver Di-Electric coated BaK-4 prisms give an amazing view with high contrast. In fact I found them as bright as the 8×42 version. The wide 137m @ 1000m field makes tracking moving targets a breeze.
So how to they compare to the lesser priced but still very good Helios Mistral 8×32 binoculars ?..I a word better in every way from build quality to field of view and optics. So in conclusion very fairly priced at £149 (price at time of this review)

The speaker at the North Lincs astro society meeting tonight was Charles Thody, who gave an excellent talk on photography using a DSLR camera on its own and through a telescope..This was a back to basics talk that was both a refresher session for some, and an introduction to astro imaging to the rest of the members who had not been present at Charles,s first talk on this subject.
The lecture was presented very well in an easy to understand way. And I,m sure it will encourage us all outside with our cameras at the next opportunity.
Around 22 members were there. Though there was an unexpected delay of milk due to there only being one cashier at the till causing the hold up (yes we believe you Sarah). This meant sadly a few of us had to survive on black coffee for a while. Sorry Sarah, only kidding, you do a great job and your efforts are appreciated

The Visionary 10×50 monocular was the natural step up for a customer who visited the Northern Optics weekend outlet, and already owned an Opticron 8×32 LER. They was looking for more magnification and clarity. The Visionary 10×50 ticked all the boxes, which included long eye relief, fully multi-coated optics and a large BaK-4 prism.
Another major plus point the customer was not expecting was the mini tripod included, that became a bespoke hand grip to keep things steady. Contact Northern Optics to check availability and the latest price

The Olivon PC 8×42 were the perfect choice for a customer visiting the Northern Optics weekend outlet at the Waters` edge centre at Barton Upon Humber.
He was looking for a high grade set in the £200 range as an upgrade for his current Pentax 10×25 binoculars. After trying a few sets of 8×42 and 10×42, the set they chose was the Olivon PC 8×42. All the binoculars felt similar and had were around the same weight, but in the customers opinion the Olivon PC 8×42 gave less of a colour cast that he found in the others.
From our point of view, this is not the first time a customer has placed the Olivon PC 42mm binoculars ahead of higher spec ED optics. This proves the point you should not judge all books by their cover, and there are some fantastic non ED binoculars that perform just as good as their low dispersion alternatives
