CED 110 and 111

Cederblad 111 (CED 111) is a blue reflection region in the southern constellation of Chamaeleon and is part of one of the closest (~550 light years) dark cloud complexes. CED 110 is the white nebula just left of centre showing a distinct arc. Both are part of the Cha I dark cloud complex. The areas of bright blue nebulosity are Hebrig-Haro objects (HH 49-50) arsing from collisions between ionised jets of gas ejected from newly born stars and the surrounding cloud.

The Cederblad Catalogue is a list of mostly reflection nebulae compiled in 1946 by Swedish astronomer Sven Cederblad.

Data for this image was sourced via Telescope Live, and acquired from the El Sauce Observatory in Rio Hurtado, Chile using an FLI ML 16200 camera paired with an Officina Stellare RH200 20cm reflector. I have also started work on a backyard version of the same region but have only acquired RGB so far. Hoping for clear skies during the next southern autumn to complete the project.

Thanks for looking and CS.

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.
