Piranga flava, now Piranga lutea
(Tooth-billed Tanager / Cardenal Montañero)
This male usually assumes this position when the female is eating and he watches over her from a certain distance, making sure that other birds do not disturb her.
Hepatic Tanager is the most widely distributed Piranga tanager, ranging from the southwest United States south to northern Argentina. Its English name is based on the liver-red color of the adult male from the northern part of the species' range; however, its scientific name, flava, meaning "yellow," derives from the original description, which is based on a female from Paraguay. These names reflect both a characteristic of the genus Piranga, marked sexual dichromatism, and the broad range of coloration, habitat, and behavior encompassed within the Hepatic Tanager as currently recognized.
Even though the Hepatic Tanager is currently considered one species, much evidence, including a recent study of molecular genetics, indicates that up to 3 species could be recognized, corresponding to the 3 groups of subspecies combined long ago. These groups and their respective species names are the Hepatic Tanager (P. hepatica) of montane pine-oak forests from the southwestern United States to Nicaragua, the Tooth-billed Tanager (P. lutea) of forest edges in foothills and mountains from Costa Rica to northern and western South America, and the Red Tanager (P. flava) of open woodlands of eastern and southeastern South America.

The Bubble Nebula is an emission Nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "Bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
The Bubble Nebula was discovered in 1787 by William Herschel.

The rainbow bee-eater is the only species of Meropidae found in Australia - Its closest relative is most likely the olive bee-eater of southern and eastern Africa, but molecular phylogenetic analysis places the rainbow bee-eater as closest relative with the European bee-eater.
The berries of the Virginia creeper resemble purple grapes and contain tiny crystals called oxalate crystals. These crystals are also in the leaves of Virginia creeper. If the leaves or berries are chewed they can cause irritation to the lips, mouth, tongue, and throat. (Google)

Bei strahlendem Sonnenschein und leicht frostiger Luft verwandelt sich Schnee manchmal in sonderbare Gebilde. In diesem Fall ist es eine Schneehaube auf einem Grasbüschel, deren Rand ich mit einem Makroobjektiv erforschte. Die Sonne stand dabei fast genau in meinem Rücken.
Selbstähnlichkeit ist ein spannender Aspekt in der Natur! Diese Eisstrukturen erinnern mich zum Beispiel an die gigantischen Gas- und Molekülwolken, in denen neue Sterne entstehen.
In bright sunshine and slightly frosty air, snow sometimes turns into strange shapes. In this case it is a bonnet of snow on a tuft of grass, the edge of which I explored with a macro lens. The sun was almost exactly at my back.
Self-similarity is an exciting aspect of nature! These ice structures, for example, remind me of the gigantic gas and molecular clouds in which new stars are formed.
Lorsque le soleil brille et que l'air est légèrement glacial, la neige se transforme parfois en de drôles de formes. Dans ce cas, il s'agit d'un capuchon de neige sur une touffe d'herbe, dont j'ai exploré les bords avec un objectif macro. Le soleil était presque exactement dans mon dos.
L'autosimilarité est un aspect passionnant de la nature ! Ces structures de glace me rappellent par exemple les gigantesques nuages de gaz et de molécules dans lesquels se forment de nouvelles étoiles.

The Perseus molecular cloud, located at the junction of Taurus, Aries, and Perseus, about 1,000 light-years away from the Earth. It contains over 10,000 solar masses of gas and dust covering an area of 6 by 2 degrees, is the closest giant molecular cloud actively forming large numbers of low to intermediate-mass stars. Unlike the Orion molecular cloud, Perseus molecular cloud is almost invisible apart from two clusters, IC 348 and NGC 1333, where low-mass stars are formed.
By accumulating a very-long-time of exposure, the dust and gas show up, exhibit a complex and chaotic structure consisting of dense cloud cores surrounded by an interconnected network of filaments and sheets. Many voids surrounded by partial arcs or nearly complete rings are also seen. This complicated structure is one possible signature of supersonic turbulence.
The eastern (upper) end of the cloud is associated with IC 348 that contains several hundred young stars. Most of the star formation in IC 348 took place within the last 3 Myr, but some stars in this region formed 10 Myr ago. The apparent age spread in IC 348 may be an indication that two episodes of star formation have occurred. IC 348 appears to be an example of a region that is at or near the end of its star-forming phase.
The western (lower) portion of the Perseus cloud contains the most active region of star formation in the Perseus molecular cloud, including the NGC 1333 cluster. It contains around 150 stars with a median age of a million years, is one of the most active sites of ongoing star formation in the sky within 1500 light-years of the Sun. The molecular ridge extending south (left) from NGC 1333 contains many Herbig–Haro objects, which are bright patches of nebulosity associated with newborn stars.
Between IC 348 and NGC 1333, right in the middle of this photo, there is an area that appears pinky, which is a low-surface brightness HII region surrounded by a dust ring G159.6-18.5, which appears to lie behind the obscuration of the Perseus molecular cloud. The intense ultraviolet light emitted by the central star HD 278942 ionizes the surrounding hydrogen, giving this region its characteristic pink color. The star appears red in this photo and would have been a blue-white star if it were not obscured by dust. The presence of HD 278942 and its HII region suggests that that massive stars may have formed in the recent past within the Perseus molecular cloud.
BTW, the cloud of dust, which obscures the central star and the HII region, is called the“Flying Ghost Nebula” because of its shape.
The area to the west (lower) of the HII region looks relatively empty without too much dense dust, and particularly dark here because the extinction in this region remains high. Perhaps this dead-zone is the youngest portion of the Perseus molecular cloud, formed by the expansion of the dust ring G159.6-18.5.
There are more areas full of dense dust to the south (left) of NGC 1333, see another photo I took if you are interested: www.flickr.com/photos/steedjoy/50855451732/

The Corona Australis Molecular Cloud is a faint gaseous and dusty molecular cloud with many embedded reflection nebulae, including NGC 6729, NGC 6726–7 and IC 4812. A star-forming region of around 7000 Solar masses, the cloud contains Herbig–Haro objects (protostars) and some very young stars. About 430 light years away, it is one of the closest star-forming regions to the Solar System.

Speravo in qualcosa di più da questa immagine, ma in questa circostanza penso di aver raggiunto veramente i limiti strumentali e i miei limiti elaborativi.
La piccola nebulosa a riflessione, denominata "Iris" (NGC7023) di colore azzurro-ciano è certamente un oggetto facile da fotografare, ma il mio vero interesse erano le interessanti nubi molecolari che la circondano insieme a quelle oscure come la VdB141 denominata "nebulosa Fantasma" e che farebbero parte del complesso nebuloso molecolare di Cefeo
Sapevo che queste nubi molecolari, molto deboli e di natura oscura erano difficili da fotografare, ma contavo su una integrazione su 6h e 25min acquisita in 3 notti consecutive.
Purtroppo questa non è bastata perchè due parametri critici hanno rovinato la maggioranza dei frame: la temperatura del sensore direttamente influenzata dalla temperatura ambientale e la non ottima trasparenza del cielo. LA temperatura ambiente media notturna è stata di circa 18-19° C e quindi quella del sensore intorno ai 26° C. Troppo rumore termico (che potete vedere qui Frame grezzo singolo dell'immagine ) che ha cancellato il debole segnale delle nubi molecolari. In minor misura ha influito la non ottima trasparenza del cielo che ha permesso all'Inquinamento Luminoso delle vicine città di rendere il cielo lattiginoso.
Per evidenziare le nubi molecolari occorre agire con molti strech successivi che in questo caso hanno evidenziato soprattutto il rumore. Ho dovuto quindi trovare un compromesso rendendo morbida l'immagine.
L'elaborazione forzata ha evidenziato anche la vignettatura anche se trattata con i flat; quindi ho dovuto croppare del 10% entrambi i lati dell'immagine.
Mi auguro che questa condivisione possa aiutare gli amici astrofili come confronto e a fare le scelte migliori in base al setup posseduto e ad altri parametri esterni.

I was hoping for something more from this image, but in this circumstance I think I have really reached the instrumental limits and my elaborate limits.
The little reflection nebula, called "Iris" (NGC7023) of blue-cyan color is certainly an easy-to-photograph object, but my real interest was the interesting molecular clouds that surround it along with the obscure ones like the VdB141 called "Ghost Nebula "and that would be part of the Cepheus Molecular Cloud Complex .
I knew these molecular clouds, poorly lit and dark nature were difficult to photograph, but I expected on an integration of 6h 25min acquired in 3 consecutive nights.
Unfortunately this was not enough because two critical parameters have ruined the majority of frames: the temperature of the sensor directly affected by the ambient temperature and the poor transparency of the sky. The average nighttime ambient temperature was around 18-19 ° C and therefore the sensor temperature around 26 ° C. Too much thermal noise (you can see here single raw frame ) that cleared the little signal of molecular clouds. The unobtrusive transparency of the sky has adversely affected to a lesser extent; in fact it has made the bright sky caused by the light pollution coming from nearby cities
To highlight the molecular clouds, it is necessary to act with many successive strechs which in this case have highlighted the noise above. I had to find a compromise, making the image softer.
Forced processing also highlighted the vignetting even if treated with the flat; so I had to cut 10% on both sides of the image.
I hope this sharing can help amateur astronomers friends how to compare and make the best choices based on their setup and other external parameters.
