Hi , during May and June, while I'm still working on a large IFN (Integrated Flux Nebula) project around Bode's Galaxy—which I need to image close to the New Moon phase—I've been capturing a few side targets on nights when the Moon phase is less than ideal.

The first of these objects is a nebula that resembles an elephant's trunk. Hence its name, the "Elephant's Trunk Nebula."

This object covers a fairly large area of the night sky, which unfortunately I can't capture in its entirety, but the main target was exactly the aforementioned trunk.

I imaged the nebula over a total of 7 nights, specifically: 25.05, 26.05, 27.05, 28.05, 29.05, 05.06, and 07.06.

Here is the exposure count for each night:

Day   | 120s
------------
05.06 | 38
07.06 | 42
25.05 | 44
26.05 | 51
27.05 | 52
28.05 | 47
29.05 | 53

Standard Gear:

  • Main Telescope: WilliamOptics Redcat 51 WIFD
  • Mount: Proxisky Ragdoll 17 Pro
  • Main Camera: ZWO ASI585MC Pro
  • Guide Scope: WilliamOptics Uniguide 31mm
  • ZWO ASI678MC (guide cam)
  • Autofocus: Gemini Focuser Pro

Software:

And Processing:

Stacking via WBPP Afterward, the following workflow was applied to the image: Dynamic Crop Dynamic Crop -> ABE -> MSGC -> SPCC -> BlurXTerminator -> NoiseXTerminator -> StarXTerminator
This produced a starless image and a separate stars-only image.
Starless Processing: GHS
Star Processing: GHS -> Curves Transformation
Combined into the final image via PixelMath, then rotated and cropped using DynamicCrop.

And below is the final photo :)
