IC405 - widefield with 200mm SLR lens

Revision title: Processed in Nebulosity 4 with a little more contrast

This is my effort at a wider field image of the stunning emission nebulae that lie in Auriga, and ride high in the sky at this time of year. I wanted to try and capture these together.

Taken with my new Hypercam 183C pro camera attached to my Pentax SLR zoom lens at 200mm, I collected 24 x 300s exposures through my Optolong L-eNhance filter. I also collected an hour of RGB data using the inbuilt UV/IR filter in the camera (Revision C), but have not included this in the final image, due to the additional noise and loss of contrast.

Collected in Nebulosity v3, pre-processed in v4, I initially processed data in Nebulosity and was pleased with the smooth outcome (Revision B). I also processed in Startools v1.8a to try and bring out more detail. I applied heavy deconvolution, star and noise reduction and am reasonably happy with the result, apart from the tell-tale amp glow on the right hand side, which my darks (taken at the time) failed to remove.

I was surprised with the quality of the star colour using this triband filter, and will not bother with taking RGB frames in future, when shooting emission nebulae, as the slight difference in focal length requires additional (unnecessary) steps to scale the images. Once I get darks and flats sorted out, this set up works fairly well for wide fields from 28-200mm.

Title: L-eNhance data processed in Nebulosity v4

Description: 120m data (300s exposures) taken through my L-eNhance filter processed in Nebulosity v4 with levels, curves, star and noise reduction.

Title: 60m (60s exposures) RAW data captured through in built UV/IR filter

Description: 60m OSC data taken with built UV/IR filter, debayered and processed in Nebulosity v4 with levels, curves, star and noise reduction. I'm not sure the star colour is any better than in the L-eNhance filter, and may stick with this filter only for emission nebulae in future (as the change in focus requires me to align, (rotate) and scale the data).

Title: Processed in Nebulosity 4 with a little more contrast

Description: Here I have applied a little more contrast to bring out the nebulosity in these wonderful nebulae - i'm particularly pleased to see a hint of the OIII which shrouds the flaming star and IC410 - I can even see two tiny tadpoles! The image comprises 120m data, 300s subs, taken through my Optolong L-eNhance tri-band filter.

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.
