Description: This version was stacked and aligned in Meade Envisage v10, then processed in Startools v1.5, but I struggled to draw out the colour, which is a bit of a fudge.

Description: Another version imaged through my Optolong L-enhance line filter. There is definitely a hint of the delicate hydrogen filaments that stream out of the core (at ~500km/s). Again, no joy with the colour, which was evident in the stacked frames in Envisage.

Description: My last version of LRGB frames taken through an Optolong L-eNhance dual narrow band filter and Meade DSI IIC one shot colour camera. 12 x 5 min frames aligned and stacked in Meade Envisage v10, and then manipulated using iPhoto editing software on my iPhone. The image is over processed and artistic at best (or worst), but has not been retouched, and does allow the red hydrogen emission regions to show up. Feel free to comment on which version you think is best. Thanks.

Description: This latest version, taken through my Optolong NBF, was developed using Startools colour constancy tool, and then further saturated. The whole image feels a bit unreal, over deconvolution has created some bizarre artefacts. Nevertheless the H-alpha filaments streaming from the core are now clearly visible, even if the cigar does seem to have caught fire.

Description: The final version colour processed in Startools. I'm happy with the level of detail and hint of the H-alpha filaments in the core. I only used an ir cut filter to reduce star bloat.

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. |
This image cannot be submitted for the IOTD/TP consideration.
