M38 and NGC 1907

Snimljeno sa Canon 1100D, TE 330/50mm apo, Star Adventurer, 90 x 2min, ISo 1600. Obrada: DSS, PI i Lightroom.

Messier 38 (M38 ili NGC 1912) otvoreni je skup u sazviježđu Kočijaš. Skup je otkrio Giovanni Battista Hodierna oko 1654. godine. Charles Messier uključio ga je u svoj katalog 1764. godine. Prividni prečnik skupa M38 na nebu je 21'. Udaljenost skupa je procijenjena na 4200 svjetlosnih godina, a prečnik skupa je 25 svjetlosnih godina. Skup je srednje starosti, oko 220 miliona godina. Skup je dvogledom moguće vidjeti u istom vidnom polju s M36. Kroz 200 milimetarski teleskop vidi se 70 zvijezda magnitude 9 i više. Skup ima neobičnu šupljinu u središtu i izražen lanac zvijezda u smjeru sjevera. U blizini skupa nalazi se tamniji skup NGC 1907 kojeg je moguće vidjeti u istom vidnom polju s M38. Sigma Aurigae (σ Aurigae, σ Aur) je zvijezda u sazviježđu Kočijaš. Ima prividan sjaj od 4,99 mag. Udaljena je 470 sg od Sunca. Ubraja se u divove spektralne klasse K4III.

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.
