The Core of the Orion Nebula

I decided to image a DSO with my f/15 telescope because ~~I hate myself~~ I just wanted to see what would happen. This telescope has been my go-to for [planetary imaging](https://www.reddit.com/r/astrophotography/comments/a70idh/the_solar_system_in_2018/) and I decided to test it out for deep sky before semi-permanently putting my ASI1600 on my Newtonian. Captured on January 15th, 2018 from a Bortle 7 zone.

**Equipment:**

* Meade ETX-125EC (**a 1900mm f/15 telescope!**)

* Orion Sirius EQ-G

* ZWO ASI1600MM-Pro

* ZWO EFW 8x1.25"/31mm

* Astronomik LRGB Filters- 31mm Mounted

* (Guiding equipment was attached but for some reason the ASI120 refused to communicate with my computer)

**Acquisition:** 1 hour 57 minutes (Camera at Unity Gain, -20°C)

* L- 138x30" (1h 23m)

* R- 32x30" (16m)

* G- 32x30" (16m)

* B- 32x30" (16m)

* Darks- 30

**Capture Software:**

* EQMod mount control. Captured using [N.I.N.A.](https://bitbucket.org/Isbeorn/nina/overview) ~~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.
