This week’s guest blog post is by Luca Marinelli. He images the sky with a Teleskop Service ONTC 10″ Carbon Tube f/4 Newtonian equipped with our Tele Vue Paracorr Type 2 coma corrector.
I have been interested in photography since a very young age. I remember learning to take pictures with my father’s Russian-made Zenit-E 35mm fully-manual SLR (you had to remember to close the iris by hand before shooting to set the desired aperture!) when I was in elementary school. I have pursued nature and adventure photography ever since and some of my images have been published.
The annual Stellafane convention, organized by the Springfield Telescope Makers, took place August 1 –4 around their clubhouse on Breezy Hill in Springfield, Vermont. This year, Al brought the Apollo 11mm eyepiece and the TNV/PVS-14 Night Vision monocular to the field. He got great comments on both. Presented here is Al’s Stellafane in pictures.
“Most exciting and encouraging throughout my life has been my annual pilgrimage to Stellafane, where in 1958 my 8-inch received 3rd prize in mechanical excellence. Years later, I rebuilt the scope into a 12-inch f/5.3 and received 1st prize for Newtonians at the 1972 Stellafane.” – Al Nagler. From “Star People – Real People in Astronomy.” Amateur Astronomy #6
We posted some Instagram sketches of the July 2019 Total Solar Eclipse from Chile last month made by Pekka Rautajoki — who traveled all the way from his native Finland to be there. We found a trove of blog-worthy images, he posted on Instagram, made with Tele Vue eyepieces and Tele Vue-85 APO refractor. They encompass a broad range of objects from the northern and southern hemispheres. So, it was only inevitable that we invited him to write a guest blog post based on his exquisite work!
Over the years, we’ve seen conversational topics in online amateur circles that repeatedly crop up concerning the definition of apochromatic refractor, triplet vs. doublet design, and how glass designation might define performance. We expect these questions to continue to appear as new amateurs discover the hobby. So bookmark this blog post because here you’ll find notes on Tele Vue’s philosophy and build practices concerning our telescope line of 100% APO refractors.
