The Kowa TSN 1

This is a scope I have been after for many years now. It was a very popular spotting scope with twitchers and birders during the late 1980’s and through the 90's.  

A very well built and quality product. The TSN 2 was the straight version, and came in two colours the green as bove and a pale beige grey. The fluorite lensed TSN 3 / 4 would follow later.

Here being used by a Selsey birder the TSN 2 straight version 

This is from the Kowa Optics History 

Released in 1984

(TSN-1, TSN-2) ReleasedThe motivation behind the development of the TSN (telescope new) scopes was "to create spotting scopes that had the world's best viewing characteristics".
These scopes utilized all the knowledge that had been gathered from years of innovative design and development. The results were the TSN 1 and 2 models which included objective lenses that were larger than the 50mm and 60mm objective diameters of the TS line.
The new products were named TSN (TeleScope New) and were the first of a new category of spotting scopes. Future models inheriting the TSN name were only those with lens aperture diameters of 82mm and 66mm that had not previously been released.

Again from Selsey the chap 2nd in from the left using a TSN 1.

Dipped again! But still some little gems - Year List 2025 - (#30).

Tuesday 18th November 2025. Shatterford Bottom - New Forest - SU 343050 .   A day spent searching for the elusive  Great Grey Shike  that didn't turn up, even with about another 20 birders looking for it too. But not all was lost, I managed to pick up another 3 species for the year list. Crossbill  -  (small flocks of male & female seen feeding on Larch cones, these were a joy to watch) .  Dartford Warbler  (4)   (one seen and the others heard).  Reed Bunting  (2)  females seen near to the large pond.  Other very notable birds were :   Kestrel   (seen in flight then hovering over the heath).   Stonechat - Great spotted Woodpecker - Green Woodpecker - Fieldfare   (1st for this winter).   Mistle Thrush - Water Rail  - (heard near the pond) . Donald Watson sketch of a Great Grey Shike. My last trip to Beaulieu Road Station or Shatterford Bottom was 28 years ago  13th June 1997. These were m...

Shaftesbury Jolly between 17th - 21st July 2023

Recent Shaftesbury walks over the past week on the Breach Common and Castle Hill trying out my new/old roof binoculars Carl Zeiss Jena Notarem 8x32b MC. As you can see I was lucky to get a pair in very good condition. The serial number  6428067 - dates them at 1985. The case was very clean too. The binoculars laid down. Adverts from the 1980's  They   seem very good indeed, are good size and particularly clear, I will probably alternate using them with my Carl Zeiss Jenoptems 8x30W.  The usual birds were seen. Bullfinches always a pleasure to see, (The bullfinches actually have been showing theirselves very well, the lovely male with a pinky-red breast down near the farmhouse at the top of a copper beech tree, and especially today) -  (20th July 2023).   Red Kite, two in one morning, the Buzzard hanging over the valley between the common and Duncliffe Woods. Other singing birds as usual Blackcap, Chiffchaff, Song Thrush, a Treecreeper was seen as well and C...
