Sharpless2 241 (aka LBN824), LBN823 above, LBN825 below. Reflection Nebula in Auriga Captured with TEC200ED @ f/9 with STL-11000M using Astrodon 5nm H-alpha filter Ha: 8x20m (1x1). March 17, 2013 (filling in some time -- need to revisit this one)
The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158. It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.
The Belt and Sword of Orion, taken from home, Feb 1, 2013. Taken as part of testing of a Hutech-modified Canon 6D camera. This is with the 135mm lens at f/2.8 and is a stack of 2 x 4 minute at ISO 800 and 2 x 2 minute at ISO 1600. Some light haze moving in.

The Belt of Orion, enmeshed in nebulosity, emission and reflection, including the famous Horsehead Nebula at left below Zeta Orionis, aka Alnitak, and with NGC 2024 the Flame Nebula above Zeta. Numerous bits of dark and reflection nebulosity fill the area as well as a large cluster of blue stars, Collinder 70.

The complex area of clusters and nebulosity in central Auriga, including: M38 the Starfish Cluster and its smaller companion cluster NGC 1907; the emission/reflection nebulas NGC 1931, IC 417, IC 410 and IC 405 (from right to left here). Magenta and cyan (from emission and reflection components) IC 405 at right is the Flaming Star Nebula. Between IC 405 and IC 410 is the asterism known as The Little Fish. This is a stack of 8 x 7 minute exposures at ISO 800 with the modified Canon 6D on the TMB 92mm apo refractor at f/4.8 with the Borg 0.85x compressor flattener. The night was a little hazy. The field is turned slightly from being oriented with North up as is usual for me, to frame the area better. North is toward about 10 o'clock on this frame.
