M63 The Sunflower Galaxy - an experimental project in combining data from two different telescopes (Andreas Eleftheriou)

M63 The Sunflower Galaxy - an experimental project in combining data from two different telescopes

This image is a combination of my own data take with an Esprit150 and an OSC (15 hours) from my balcony in Limassol Cyprus and 2 hours data (applied as L) from telescope T18 (Planewave CDK 318mm) from AstroCamp (itelescope.net) in Spain. Although the pixel scale is almost identical, due to the different orientation of the cameras, there is no colour in the four corners of the final image :-)

The amount of details in just 2 hours Luminance exposure from a dark sky, wins over the 15hours data from my Bortle 6/7 skies!

Revision A: The final, cropped L(RGB) image (cropped to avoid colourless stars).

Revision B: The original image, cropped, used as RGB (mouse over to compare).

Revision C: The actual processed, uncropped L data from the T8 (Planewave CDK 318mm) from AstroCamp (itelescope.net) in Spain (mouse over to compare).

Revision D: The original image, aligned, used as RGB (mouse over to compare).

Revision E: The final, uncropped image L(RGB), with uncoloured stars at the four corners.

This was a very interesting experiment in order to evaluate the effects of the light pollution in capturing the faint halo/structure around the galaxies and how the data acquired from telescopes in dark skies can be used to enhance the images taken from our back yards in light polluted cities.

I hope you like this, I had a great time working on this project!

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.
