SH 2-157 Lobster Claw Nebula - telescope processed image with LP Filter and Moon and Sky Light Filter. The SH 2-157 Lobster Claw Nebula is an emission nebula in the constellation Cassiopeia, shaped by the powerful winds of giant stars, including the Wolf-Rayet star WR 157.

SH 2-157 Lobster Claw Nebula - unprocessed image with LP Filter and Moon and Sky Light Filter. It has a famous neighbor! SH 2-157 is found near the well-known Bubble Nebula (NGC 7635) in the constellation Cassiopeia.

Good Tuesday morning. Decided to let the s50 perform some mosaics and longer observations durning this week. This will result in only 2 images a night for the next 4 mornings. Some of these images I hope to use in a large mosaic I wanted to put together. In […]

SH 2-157 Lobster Claw Nebula - telescope processed image with LP Filter. This emission nebula (Sh2-157) in Cassiopeia gets its name from its distinctive arc, shaped by the stellar wind of a powerful Wolf-Rayet star.

Here are the results of #SH2-157 #LobsterClawNebula with the LP Filter on. Much better observation than last morning. #seestar #S50 #space #astronomy #amateur

SH 2-157 Lobster Claw Nebula - telescope processed image with Moon and Sky Light Filter. The Lobster Claw Nebula (Sh2-157) is a large, colorful emission nebula in Cassiopeia . Its ring-like shape is sculpted by the stellar winds of a massive Wolf-Rayet star.

Here is what I got observing #SH2-157 #LobsterClawNebula. Going to try with the LP onboard filter tonight to see if I can get a better image. #seestar #S50 #space #astronomy #amateur

As I am now into my second year of astrophotography, I am re-imaging objects in the Cygnus-Cepheus-Cassiopeia constellation corridor with techniques I have improved upon. The area is chock-full of targets. So full, in fact, that I ran out of time last year to image this one before it passed out of view for the winter. Lobster Claw Nebula is a new one for me and I'm glad I finally got to it. This is an exciting target because most astro targets have a rounded, bulbous look, but the Lobster Claw has two arcs that converge to a definitive angled point, lending to its namesake. Even in sub-exposures, it's possible to make out a shape that resembles the business end of a lobster. The Lobster Claw Nebula is a planetary nebula 11,000 light years away and is primarily composed of Hydrogen. Stewart Sharpless discovered it in 1959. As a complete surprise, I also captured the Bubble Nebula, located near the bottom of the image. I didn't realize the two nebulae were so close to one another and will compose this differently in future imaging sessions.

It’s been weeks of mostly clouds here in Michigan. Time to hop a 🚀 and head to some far away places.
