ngc4725 + PN LoTr 5 (superlum_HOO_RGB)

ngc4725 + LoTr 5 captured in LHaO3RGB and processed in superlum_HOO_RGB. Superlum is a combination of true luminance(120 x 60s) and synthetic luminance(194 x 60 s) layers. HOO_RGB is performed with SHO-AIP script.

This faint planetary nebula is most commonly referred to as LoTr 5, short for Longmore-Tritton 5. It was discovered in 1980 by A. J. Longmore and S. B. Tritton, who found the nebula on photographic plates taken at the UK Schmidt Telescope which is a 1.24 meter Schmidt telescope operated by the Australian Astronomical Observatory(source wikipedia). Its distance from earth is 1650 ly.

Please look at the animated revision C that shows ngc 4725 captured with the C8edge HD (details: https://www.astrobin.com/kbnari/B/) superimposed on the one captured with the APO 50/844mm.
you can appreciate the resolution and colorful differences

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.
