The Elephant's Trunk Nebula

Gorgeous nebula found in the constellation of Cepheus has been the focus of my attention and the attention of my tiny little scope for the past few weeks, work, clouds and the fading end of light skies from British "summer" have been all against me.

This is now a complete "bi-colour" image of this impressive nebula, with Sulphur II mapped to Red and Hydrogen Alpha mapped to Blue.

This image is a stitch of three panels, each panel made from 20x480s Ha and 20x960s SII, all taken from my suburban garden using a Meade LX90 8" SCT reduced to f/6.3 and captured via an Atik Cameras 414ex mono.

Guiding was via OAG/ASI120mm with PHD controlling that side of things.

Once the data was grabbed, I stacked in DSS, using a preset selection of reference frames and then the mosaic is put together in Microsoft's "ICE", or Image Composite Editor - which is far simpler than "Hugin" and more consistent than Photoshop's "photomerge" feature.

After that, it goes in to Photoshop for channel mixing and levels, almost nothing else done to it, I like the palette here as it's not the albeit more accurate blend with Ha as red, but a more ghostly blue.

So what next, well....just need 16 hours of clear sky to get that OIII data in and make this a full Hubble Palette photo!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
