Strange Pillar like Formation in IC 1805, The Heart Nebula

This is an object in the Heart Nebula that I have captured from time to time. My previous photo was taken in 2012.
This new photo reveals more details, even though the exposure time for H-alpha light was only 5 hours.

The pillar-like formations are typically pointing toward a source of ionization, in this case, the more famous Melotte 15.

I haven't been able to find a name for this beautiful object

A Fossil Footprint Nebula, NGC 1491

 I have shot this emission nebula in Perseus several times during the years and every time felt that I got more out of it.

I have wide field and mosaic images including the NGC 1491 as well as longer focal length photos with various reflecting telescopes. Some of them are included in the blog post as an example

INFO

NGC 1491, also known as LBN 704, SH2-206 or the Fossil Footprint Nebula, is an emission type bright nebula located about 9,800 light years away from Earth in the constellation of Perseus. The nebula gets its deep red coloration due to many massive stars (such as BD+50 866) embedded within NGC 1491 producing large amounts of ultraviolet radiation ionizing the elements in Nebula and making them glow light that can be seen in this image

Soul Nebula, IC1848

This is a new photo of this beautiful emission area in Cassiopeia. I'm using a long focal length telescope, Celestron EDGE HD 14" at the moment for a high resolution imaging work. This tool together with a second hand Apogee Alta U 9000M camera with a 12 micron pixels delivers deep images with lots of details.

INFO

Soul Nebula, (Sh2-199, LBN 667) is an emission nebula in constellation Cassiopeia. IC 1848 is a cluster inside Soul Nebula. Distance is about 7.500 light years. This complex is a Eastern neighbor of IC 1805, the "Heart Nebula" and they are often mentioned together as Heart and Soul.

Melotte 15 in heart nebula, IC 1805

 I shot material for this new photo back in February, 10 hours of exposures total for three narrowband color channels. (H-alpha, O-III and S-II)
