The famous Horse Head (Barnard 33) and Flame Nebula (NGC 2024), in the region surrounding Alnitak, the bottom/left star in the Constellation Orion's belt. LRGB composite (luminance weight limited), Red, Green, Blue, and a pinch of H-Alpha. Roughly 3 hours of combined exposure. Stacked and processed in MaximDL. Image by M. Polansky with JJMO equipment. — Horse Head and Flame Nebulae

Same specs as the other Horse Head image, but with improved processing techniques to reduce the brightness of Alnitak, with better contrast and detail in the Flame and Horse Head Regions. Stacked in MaximDL, processed with layer masks for a High Dynamic Range effect in Photoshop. — Horse Head and Flame v2

Same raw images as the other M27 Revisited image, processed a different way. Luminance image was deconvolved using CCDSharp, H-Alpha and OIII were combined as RGB in MaximDL (HA red, OIII as blue and green). Luminance was applied in Photoshop, along with inverse masking to reduce noise, and unsharp filters to increase clarity. — M27 - Dumbbell Nebula Revisited v2

RGB Composite, using Red, Green, Blue and Luminance filters primarily on the Takahashi FSQ-106. Luminance frames of the core taken on the 16" Meade were composited in for added detail. Roughly an hour and a half of combined exposure time, under less than ideal conditions (moon, fog, clouds, or some combination over the course of 5 nights).

A wide field view of the major components of the Veil Nebula- a supernova remnant in Cygnus. Visible are the Western Veil (Witch's Broom), the Eastern Veil (Caldwell 33), and Pickering's Triangle. Taken with an astro-modified Canon EOS 6D DSLR on the Takahashi FSQ-106 over two nights in mid October 2015. The true color view is made up of 80 minutes each of H-Alpha and Oxygen III, with 4 minute sub-frames at ISO 12800. Also included is 10 minutes of Luminance- all visible light (10x1 minute at ISO 12800) to enhance coloring in background stars. Stacked and processed in PixInsight, with final touches in Photoshop. — Complete Veil Nebula

This 4 image mosaic of the largest and only naked eye visible galaxy in the sky was taken over 6 nights in late fall 2014 (October - November). It was shot through the Takahashi FSQ-106ED with the SBIG ST-10XME camera with each of the 4 sections comprised of roughly 45 minutes of Luminance, 20 minutes of the colors Red, Green, and Blue, using 2 minute 30 second exposures binned 1x1 for each filter. Processing done in MaximDL, PixInsight, and Photoshop. — M31 - Andromeda Galaxy

The best of both worlds- this images combines the wide field optical quality of the Takahashi FSQ-106 with the light gathering power of the 16" Meade. Cropped from the full size image, the base images are the same as the previous M33 image, with 16" images of the core aligned and seamlessly blended. Processing done in MaximDL and Photoshop, done by M. Polansky. — M33 - Triangulum Galaxy Revision 2
