Celestron Lenspen cleaning accessory 93575

celestron_lenspen_northernoptics_93575

The Celestron Lenspen is without doubt my personal favourite lens cleaner. The simple to use accessory comes with a brush at one side for getting the dust off, and a fluid free pad at the other side for removing grease , finger marks etc. With a cap that doubles as a cleaner for the pad, it is a great all in one solution

Visionary HD 8×56 binoculars. Soft rubber eye cups VI331264

HD-856_northern_optics

A customer at the Northern Optics outlet was looking for a good quality set of binoculars for general use. After trying a few sets of twist eye cup types, they decided the solid cups did not feel comfortable against their eyes.

So they were introduced to the Visionary HD range with their soft fold down eye cups. Immediately they noticed the difference and improvement with how they felt when looking through them. Eye cups aside, the customer was impressed with the performance of the HD 8×56 in relatively low light conditions

This is one of many examples where you really need to try out a set first, to see if the optics and in this case the feel of them suit the individual buyer

North Lincs astro meeting Monday 5th September 2016

heritage 100

Hurrah !, after an eternal wait, the North Lincs astronomy society finally had a meeting with clear skies. This meant that thanks to Paul Cotton and his fantastic large Skywatcher flex-tube telescope we were given some amazing views of nebula , star clusters and a double star.

But before that we were given an excellent talk on scopes and how lenses and mirrors work , and the advantages / disadvantages of each design in his own easy to understand style.

Thank you as always to the wild life trust for the use of the venue and Sarah for the teas and refreshments. Around 20 members were in attendance

Visionary Nature Scout 20×50 monocular review VI332469

img_1075

The Visionary Nature Scout 20×50 is a limited edition bundle designed for long distance terrestrial use, plane and ship spotting.

So out the box you are greeted by a tidy and uncluttered monocular. Focus is done by turning the eyepiece. This design uses porro prism optics which like for like give better performance than roof prism. The spec is Bk7 prisms with fully coated optics. But they still give better than expected sharpness and contrast with an acceptable field of view. But by far the biggest plus point was the eye relief. I found that with the eye cup folded down, I was able to get full view with spectacles on. Also the fold down eye cups stay down when folded.

With the kit as standard the Visionary Nature scout 20×50 comes with lens caps, case, wrist strap and mini table top tripod. There may be an option of a hand grip depending on where you buy from

Maybe not recommended for bird watching. But for longer distance work, the Nature scout 20×50 monocular will not disappoint

does edge of field quality matter with binoculars

  1. Often in reviews we see comments about edge of field quality. This includes myself. So how important is sharpness on the outer view ?. With an example looking at a bird in the center of the view, the most important factor is the sweet spot in the center where the target is. Intact the out of focus area around the bird may make it stand out more. However if you like looking at the whole picture including the surroundings , then a set with what we call a flat field will be suitable

visiony M40 magnifier 331905

 

The visionary M40 magnifier comes in a handy pouch for safe keeping. Also has a soft neck strap. As for the magnifier itself the power is not quoted, but I would guess at 3x

I would reommend for close up work such as looking at jewellery rather than larger objects such as reading large sections of text. The design of this mag glass means it needs to be held close to the eye. I find the subject needs to be around 3 inches from the eye for best result’s
