"Imaging Sunlight - Using a Digital Spectroheliograph"

Post by Merlin66 » Fri Apr 29, 2016 11:22 pm

The "Imaging Sunlight - Using a Digital Spectroheliograph" book should be available next month.
Final cover.JPG
Final cover.JPG (136.61 KiB) Viewed 7251 times
This 290 page book covers everything from a historical review of solar observing, commercial filters available to the amateur, white light and narrowband solar imaging as well as extensive details on the construction and use of the SHG. Construction details and results from all the current SHG's from around the world are discussed, as well as the historical SHS.

I believe with the advent and application of fast frame cameras that the SHG will be able to replace the $$$$ commercial solar filters in the near future.

I acknowledge the help and assistance given by solar amateurs around the world in making this such a comprehensive book - especially Fred Veio who kept the dream alive.
(It is also dedicated - In memory of Walter Koch (Swisswalter) in acknowledgement of his contribution to amateur solar astronomy -"Only stardust in the wind")

I hope you find it interesting and informative.

OUTSTANDING!

Please allow me to advertise this book when it becomes available to our 70,000+ social media followers. I am overjoyed to read this.

Stephen,
Thanks for that!
I'll confirm when it's available - Springer says next month.....(it's been a looong wait, the final manuscript was submitted in Early Oct 2015)

Unfortunately there was one significant omission....the fantastic work of Walter J Semerau didn't make it to the final cut.
Semerau built various SHS and SHG's in the 1940 through the 1960's and his articles are mandatory reading:
Scientific American, April 1958
Sky&Telescope: (volume/page)
17/368
18/679
18/643
34/329
36/51

I'd be very interested to know what happened to him....
The last known address was in Zimmerman Blvd, Kenmore, NY.

Ken I look forward to it .I have seen a few friends and even family compile specialist books related to their hobbies/obsessions and know that it is a labour of love.Just pre-ordered it on Amazon so I won,t forget
Well done.

Sounds great; you must elated to see the fruits of your hard work.
I love the dedication to Walter whose contributions and humour are greatly missed.

great!! cant wait until I get it

Ken as far as W J Semerau
I have one of those original S&T 1959 articles
I was 5 at the time
so
Im in my 60's now
if you assume he was in his mid twenties at the time
he would be in his 80's by now

you may want to contact Buffalo amateur astronomers (NY)
he was a member and I believe a board member at least until 1980's
they may know
your a known name in the AA field

I know address stated in 59 article was sold in the 2000's
that's a matter of public record in NY state

Walter passed away in November, 1996. Quite the craftsman, anyone who builds a Lyot filter gets a tip of my hat.
Observing the Sun with complex optical systems since 1966, and still haven't burned, melted or damaged anything.
Not blind yet, either!
Light pollution? I only observe the Sun, magnitude -26.74. Pollute that!
