IC2948 - Lambda Centauri (Rodney Watters)

IC2948 - Lambda Centauri

An area of nebulosity in Centaurus surrounding the star Lambda Centauri which is often referred to as the "Running Chicken Nebula". This image has been taken with a Canon 60Da DSLR piggy backed on top of my main imaging OTA, a Tak TSA120. The Canon 60Da was imaging through a Tak FSQ106. It was an experiment to test out a couple of concepts. One was that I wanted to see how my mount behaved carrying the extra payload - it worked fine and guiding was operating very well throughout the data capture. I also wanted to test out the concept of capturing wide field data simultaneously whilst imaging a smaller field with the main scope. Guiding and mount control was operating through the main scope whilst the piggybacked set up was only capturing data. Auto focus was operating on both the main scope and the piggyback scope. Throughout the data capture session that was being run on the main scope, the Canon 60Da was clacking away taking 3 minute exposures at ISO 800. The set up worked well and has established the concept as a workable option for future projects. See image Revision ‘C’ for a picture of the set used for this project.

I was pleased to see how well the Canon 60Da brought out the colour and depth of the Ha present in this region. I have had this camera for a few years and produced some good images from it but this is the first time that I have pushed it with a solid 3+ hours of integration time. This worked well to the extent that I hardly had to apply any noise reduction at all. Pixinsight is the main processing software and I used the Starnet process to remove the stars prior to enhancing the nebula and then recombining with the original image.

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.
