NGC2244 Rosette Nebula (MON) - To the Heart of the Rose (with the C8 EHD)

My first ‘real’ attempt at a DSO through the C8. Up to now, I had been mainly chasing the moon and some planets. But with the moon being past full moon, and well past bed-time, and the planets slowly floating away, it’s time for something else

I re-fitted the camera from the TS94, and aimed at some DSO’s for a couple of nights, getting experience on DSO imaging with the C8, improving on the scope balance and the guiding, etc ….

I aimed at the heart of the rose, slightly off-centre to fit the open cluster and some of the dark clouds near the heart into the frame

Data from a couple of nights, no special filter, just the L-Pro, straight processing, no channel splitting.

A bit under-satisfied with the colours, nebulosity seems reasonable. Seems a bit low on the nebulosity for 6hrs, but maybe that’s because of the f10 of the C8, given that my reference has mostly been f5 scopes. Somehow I’m not sure about the starts and the overall image. Seems ok-ish, but not sure what’s wrong with it …

Title: Re-processed using BlurXTerminator, StarXTerminator

Description: A full reprocessing, using some new techniques that I applied in later posts, now using BlurXTerminator and StarXTerminator. Deconvolution has helped to get the nebula a bit crispier. But I seem to have developed spike-artefacts on the bigger stars, which also seem to have some chromatic aberration. Not sure what’s the cause of this. Smaller stars seem ok.
Happy to hear your thoughts and suggestions

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.
