Paracorr Type-2: Imaging the Skies with Luca Marinelli

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.

The Rosette Nebula (NGC 2244): Animals on Parade by AstroBin user Luca Marinelli. All rights reserved. Imaged through Teleskop Service ONTC 10″ f/4 Newtonian with Tele Vue Paracorr Type 2 coma corrector and ZWO ASI1600MM Pro mono camera. The narrowband filters used for imaging reveal various layers of material within the heart of the Rosette. The resulting dimensional quality draws the viewer from the ruddy edges of the nebula into the aqua-colored center and then out the “back” aperture of the structure. Filters used in this Hubble SHO palette image were: Astrodon Narrowband 3nm: Ha (26×300″, 44×360″), OIII (74×360″), SII (4×300″, 54×360″) with Gain: 139, Offset: 50 for a total integration time of: 19.7 hours. Software: Main Sequence Generator Pro, PHD2 Guiding, PixInsight 1.8, & Photoshop CC.

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.

You may know that Tele Vue’s Paracorr Type-2 accessory is the color-free cure for coma (star elongation) in fast Newtonians. But did you know that Paracorr™ users can enjoy their coma corrected Dob/Newts with two eyes using Bino Vue? Continue reading “Technote: Using Bino Vue with Paracorr”
