![]() ![]() LRGB data was done with Gain: 76 and Offset: 30 while Ha data used Gain: 139 and Offset: 50. These star-forming regions are created due to hydrogen in the arms being compressed by tidal forces from nearby companion galaxies. The galaxy core is composed of older yellowish stars while the bluish tint in the spiral arms are young stars formed in the pink star-forming regions throughout the arms. Imaged through Teleskop Service ONTC 10″ f/4 Newtonian with Tele Vue Paracorr Type 2 coma corrector and ZWO ASI1600MM Pro mono camera. The Pinwheel Galaxy (M101) by AstroBin user Luca Marinelli. Of course, shortly after a real imaging telescope was next and the rest, as they say, is history. That didn’t deter me, I bought an equatorial mount and started pointing my camera lenses to the sky. Immediately I decided to try and connect my DSLR to it. The moment I put my eye on the wobbly eyepiece I was hooked. I looked around and bought a Celestron NexStar 102SLT. Almost two years ago, for my oldest son’s fourth birthday, my wife and I decided that it would be fun to get a little telescope as a present for him. In graduate school, I had friends in the astrophysics and astronomy departments, but I never formally studied astronomy. I am a physicist and, professionally, I am a different kind of imager: I develop technologies for brain MRI at GE Research. Software: Main Sequence Generator Pro, StarNet++, PHD2 Guiding, PixInsight 1.8, & Photoshop CC. Filters used in this Hubble palette photo were Astrodon Narrowband 3nm series Ha (28×1200″), OIII (41×1200″), & SII (30×1200″) for a total integration time of 33.0 hours. But there is another famous object to see here: The faint blue arch to the right of the Tulip Nebula is the shock front of powerful jets from the black hole accretion disk in the Cygnus X-1 system. This emission nebula in the constellation Cygnus glows by ultraviolet light emitted by an association of young “O” and “B” type giant stars. Imaged through Teleskop Service ONTC 10″ f/4 Newtonian with Tele Vue Paracorr Type 2 coma corrector and Atik 383L+ Mono camera. The Tulip Nebula (Sh2-101) and Cygnus X-1 Bow Shock by AstroBin user Luca Marinelli. I have pursued nature and adventure photography ever since and some of my images have been published. 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 been interested in photography since a very young age. Software: Main Sequence Generator Pro, PHD2 Guiding, PixInsight 1.8, & Photoshop CC. 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. 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. The narrowband filters used for imaging reveal various layers of material within the heart of the Rosette. The Rosette Nebula (NGC 2244): Animals on Parade by AstroBin user Luca Marinelli. ![]()
