The Fighting Dragons on Cepheus

Posted on May 4, 2023May 15, 2023

(LBN552 and LBN1228 wide field on LRGB)

This is my first attempt using the new Sigma Art 135mm f1.8 lens and ASI294MM-C camera.

The field of view (FOV) was amazing, covering a wide angle of 5º

Although I require further practice to fully explore the capabilities of this new optic, I am delighted with the initial results of this test.

LBN 1228 is a region of gas and dust that is illuminated by the intense radiation from nearby young, hot stars.
It is also sometimes referred to as Sharpless 2-132 or Sh2-132.LBN 552, on the other hand, is also an emission nebula located in the same region of the sky as LBN 1228, and is sometimes referred to as Sharpless 2-138 or Sh2-138.
It is thought to be approximately 4,000 light-years away from Earth and is estimated to be around 30 light-years across.

Like LBN 1228, LBN 552 is a region of gas and dust that is illuminated by nearby young, hot stars.
t is also known for its intricate filaments of gas and dust, which create a beautiful and unique appearance.
