Tele Vue-NP101is: Imaging the Skies Over Southwest Florida

Rosette Nebula and NGC 2244 Cluster (Narrowband) by SmugMug user Linwood Ferguson. All rights reserved. Used by permission. Imaging details: the Tele Vue-NP101is APO (Nagler-Petzval) refractor (101mm, f/5.4), riding on an iOptron CEM70G mount, imaged with a ZWO ASI6200MM Pro camera, with ZWO Filter Wheel and Chroma 5nm narrowband filters. All subframes were 300s using these filters: Hα x 47, SII x 37, OIII x 31. (The OIII had a pretty strong gradient from the moon). Stacked and processed using PixInsight in roughly the Hubble Pallet with green shifted into blue and gold (star color shifted off magenta a bit). Finished off in Photoshop Lightroom Classic 10.0 (Windows).

The lead-off image of this post is certainly an eye-grabber! It is one of the most unique interpretations of the Rosette Nebula (NGC-2237 or Caldwell 49)  in Hubble Palette filters we’ve seen. Most striking, the usual Hubble Palette aquamarine color surrounding the central cluster is cobalt blue! The typical outer ring of yellows and burnt ochre now has a deep-orange hue. This color manipulation was done while maintaining the filamentary wisps and dark protostar Bok Globules in the nebula, along with a jet-black sky background.  The resulting dimensional quality of this image draws the viewer from the ruddy edges of the nebula into the blue-colored center and then out the “back” aperture of the structure.

In the middle of the Covid pandemic, stuck at home, I decided to resurrect an interest in astronomy, and in particular astrophotography.

This image is from a great collection of Tele Vue NP101is images posted by Linwood Ferguson on SmugMug. At the top of this SmugMug page is stated the motivation for his astro imaging: “In the middle of the Covid pandemic, stuck at home, I decided to resurrect an interest in astronomy, and in particular astrophotography”. In this blog, we present a gallery of Linwood’s NP101is images.

Virtual NEAF 2021: Your Questions Answered!

Due to the continuing COVID-19 crises, the Northeast Astronomy Forum (NEAF) — “the World’s Largest Astronomy & Space Expo” — will be a “virtual,” online-only affair for the second year in a row. However, that is not all bad: it allows people from around the world —  who might normally not travel to New York — to experience this special show. It’ll be FREE too!

Last time in this blog we asked for your Tele Vue product questions which would be answered on videos and played at the virtual NEAF on April 10th. The response was tremendous! Though time and slots were limited, we were able to produce seven videos for the show. Each video provides a “front-row” seat to the answer from David and Al Nagler. Below you can view a 1-minute “sneak peek” video of what to expect.
