M8 & M20 Wide Field

I imaged these nebulae from my back porch in Illinois using a Takahashi FSQ-130ED and a 645 reducer on 6/15/20. Eleven images were captured at ISO 800 for 180 seconds. The images were stacked with DSS and the combined image was processed in Photoshop. No flats, darks or bias frames were used. I did use a Skytech LPRO-MAX filter. Guiding was done with a 60mm scope and a ZWO camera with PHD2 and APT software. Main imaging camera was a Canon Ra. This is the first time I have had a chance to image these nebulae since 1994 when I used a Nikon film camera, a 225mm Takahashi SCT and no guiding. Of course I could only get the Lagoon in the field of view with that scope and I always wanted a scope that would capture both nebulae. I had to wait quite a while but now I have a scope that will do it.

Description: I am fairly new to post processing in that I retired in 2017 and didn't have the time to study on this until then. Yes, I started imaging in 1992 but it was very sporadic. Anyway, I have a lot to learn but can see where I overdo stuff such as saturation, shadows and highlights etc. Anyway...I started looking at my earlier files where I started stretching the image and came up with this one which is more subdued.

Title: Lagoon & Trifid Nebulae

Description: I have migrated to PixInsight but still use Photoshop for some of my processing. I took the eleven 180 second exposures and stacked them in PI with WBPP and then used DBE and SPCC and Russell Croman's wonderful tools. I then took the starless image and the star image into Photoshop and ended up with this final result.

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.
