M48 - Open Cluster in Hydra

Although I originally planned on only testing out filter offsets for my focuser, I finished that early and decided to image another open cluster. I believe I have imaged 5 star clusters this month (clear skies during full moon week and no good Ha targets). For the curious [here is an annotated image](https://i.imgur.com/5mgsEQs.jpg) that points out faint galaxies in the background. Captured on March 20th, 2019 from a bortle 7 zone.

**Equipment:**

* TPO 6" F/4 Imaging Newtonian

* Orion Sirius EQ-G

* ZWO ASI1600MM-Pro

* Skywatcher Quattro Coma Corrector

* ZWO EFW 8x1.25"/31mm

* Astronomik LRGB Filters- 31mm

* Agena 50mm Deluxe Straight-Through Guide Scope

* ZWO ASI-120MC for guiding

* Moonlite Autofocuser

**Acquisition:** 1 hours 45 minutes (Camera at Unity Gain, -20°C)

* Lum- 86x30"

* Red- 20x60"

* Green- 21x60"

* Blue- 21x60"

* Darks- 30

* Flats- 30 per filter

**Capture Software:**

* EQMod mount control. Captured using [N.I.N.A.](https://nighttime-imaging.eu/) and PHD2 for guiding and dithering.

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.
