M8 from Bortle Class 8 through a window with unmodded DSLR

Up until now, every time I went out to capture DSO, I was just trying to solve problems on the go, in darkness ….and never really getting good results.

During current lockdown in Spain, obliged to stay at home, I decided to set the telescope as close as possible to a southeast looking window in my flat, right in a city centre with Bortle 8-9 scale.

Initial idea was to practice all those skills that are needed to take pics of deep sky objects (polar alignment, focus with Bathinov mask, autoguiding with PHD, collimate optics, etc), so I could be ready as soon as free movement is authorized.

It’s amazing how much time is required to really understand all steps at DSO imaging! I practice for several nights and, at the end, I decided to point to the Lagoon Nebula and try. 3 minutes subs were the maximum exposure time before clipping in the blue channel (CLS filter).

I could not believe how good the image was after the initial post-processing steps with Photoshop! So, I kept capturing M8 for two consecutive nights to get a total of 60 subframes with an unmodded Canon 800d!

My post-processing skills have also improved a lot, thanks to Trevor at AstroBackyard tutorials.

Current situation is very difficult to everybody and I hope to inspire others to try silly things looking through a window!

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.
