Shelob's Lair (Mark 2)

Shelob lies in wait, anticipating the harmonious twang as her next meal becomes entrapped in her web. You can see the remains of a small scorpion to her left, a previous meal.

The Tarantula nebula is a massive HII region within the Large Magellanic Cloud. The weather was briefly good here and the seeing was exceptional. This is 6 hours of SHO data captured from my backyard. Hopefully the weather will clear again so I can continue to capture photons of this beautiful region of space.

I've added nearly double the data to my original image and decided that while I usually love the SHO palette it wasn't working for Shelob, so I went with a more duo tone look.

I am hoping to capture much more OIII and SII data in the coming months, the Ha stack looks good now.

I took only the best frames based on FWHM and used them to create a synthetic luminance, this layer received deconvolution and sharpening.

C

Description: An alternative version, with a more careful noise reduction on the luminance and less aggressive stretch. (I uploaded the wrong file before this one if any wonders why this version changed).

D

Description: An alternative framing, a touch wider. Not sure I like it better, I think I do.

Uploaded: ...

E

Description: Decided to use all 20 hours of data weighted using subframe selector. There is a moderate loss of sharpness compared with only using the best 5.5 hours of ha as luminance but a very significant reduction in background noise.

F

Description: Another ground up reprocess of the full 20 hours of data.

G

Description: Shelob reprocessed using the Foraxx palette.

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.
