Prove con OSC da cielo cittadino Bortle 7-8.

La Elephant Trunk l'avevo già ripresa anni fa, con un ccd mono e in banda stretta da un cielo Bortle 3-4.

Ho voluto vedere come veniva dalla città con una OSC e un filtro Optolong L-eNhance.

Insomma, qualcosa è venuta ...

Nebulosa non inquadrata bene.

In ogni caso preferisco la versione SHO che feci dalla Sardegna.

Brutto seeing che ha portato le stelle ad allargarsi.

*****

Tests with OSC from city skies Bortle 7-8.

I had already shooted Elephant Trunk years ago, with a mono and narrowband ccd from a Bortle 3-4 sky.

I wanted to see how it came from the city with an OSC and a L-eNhance Optolong filter.

In short, something has come ...

Nebula not framed well.

In any case, I prefer the SHO version I made from Sardinia in 2016.

Bad seeing but which PHD2 managed to handle with the multi-star guide.

SGPro's focus routine returned an HFR of 2.4" ... enlarged stars

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.
