IC 410, nota talvolta come Nebulosa Girino a causa dei suoi filamenti nordorientali, è una nebulosa a emissione di grandi dimensioni visibile nella costellazione dell'Auriga; ad essa è legata l'ammasso aperto NGC 1893, formato da giovani stelle massicce piuttosto disperse. La regione è sede di importanti processi di formazione stellare generanti stelle di grande massa.
Il periodo più indicato per la sua osservazione nel cielo serale ricade fra i mesi di ottobre e marzo ed è notevolmente facilitata per osservatori posti nelle regioni dell'emisfero boreale terrestre.(Wikipedia)

IC 410, sometimes known as the Tadpole Nebula because of its northeastern filaments, is a large emission nebula visible in the constellation Auriga; linked to it is the open cluster NGC 1893, formed by rather dispersed young massive stars. The region is home to important star formation processes generating high-mass stars.
The most suitable period for its observation in the evening sky falls between the months of October and March and is considerably easier for observers located in the regions of the Earth's northern hemisphere. (Wikipedia)

Ultima ma gratificante fatica prima di un pò riposo ...
La Galassia del Triangolo, conosciuta anche con il nome di M33 (oggetto numero 33 del catalogo di Charles Messier) e di NGC 598, è una galassia a spirale distante circa 3 milioni di anni luce dalla Terra e situata nella costellazione del Triangolo. La Galassia del Triangolo è la seconda galassia non nana più vicina alla Via Lattea dopo la Galassia di Andromeda (M31). Può essere vista con un binocolo sotto cieli bui, attraverso il quale si presenta come una macchia ovaleggiante e dai contorni irregolari; sotto un cielo eccezionalmente buono, dove l'inquinamento luminoso è sufficientemente basso, è persino possibile notarla ad occhio nudo.
Come si vede nella foto , nella Galassia sono ben visibili numerose regioni HII (di colore rosso formate da idrogeno ionizzato) ,Herschel catalogò la regione H II più brillante della galassia del Triangolo come H III.150, separatamente dalla galassia. La regione H II, che finì poi con l'avere la designazione NGC 604, si trova nell'angolo nord-est di M33 ed è una delle regioni H II più grandi conosciute con un diametro di quasi 1500 al. Herschel notò inoltre altre tre regioni H II più piccole appartenenti in realtà alla galassia del Triangolo che presero il nome di NGC 588, NGC 592 e NGC 595(Wikipedia).
In questa foto ho unito le acquisizioni in RGB con quelle in Ha per evidenziare le zone HII.

Last but rewarding effort before some rest...
The Triangulum Galaxy, also known as M33 (object number 33 in Charles Messier's catalogue) and NGC 598, is a spiral galaxy about 3 million light years away from Earth and located in the constellation Triangulum. The Triangulum Galaxy is the second closest non-dwarf galaxy to the Milky Way after the Andromeda Galaxy (M31). It can be seen with binoculars under dark skies, through which it appears as an oval-shaped spot with irregular outlines; under exceptionally good skies, where light pollution is sufficiently low, it is even possible to notice it with the naked eye.
As seen in the photo, numerous HII regions (red in color formed by ionized hydrogen) are clearly visible in the Galaxy. Herschel cataloged the brightest H II region of the Triangulum galaxy as H III.150, separately from the galaxy. The H II region, which came to have the designation NGC 604, is located in the northeast corner of M33 and is one of the largest known H II regions with a diameter of nearly 1500 al. Herschel also noticed three other smaller H II regions actually belonging to the Triangulum galaxy which were named NGC 588, NGC 592 and NGC 595 (Wikipedia).
In this photo I combined the RGB acquisitions with those in Ha to highlight the HII areas.

Filar Micrometer for Astronomical Telescope, produced by W. & S. Jones (William & Samuel Jones) in the first decade of 1800, and used by means of a telescope, to calculate the angular distances of celestial stars such as, stars, planets and asteroids.
It is complete with four eyepieces, of which respectively 80, 100, 130 and 180 magnifications, through which observations are possible from relatively closer distances up to much more considerable ones.
The belonging and use of this instrument can be traced back to the famous astronomer Alfred Henry Fison (1857-1923) as, inside the original mahogany box which contains both the instrument and the eyepieces, There is a label which shows, in addition to the name of A. H. Fison, also some handwritten technical notes attributable to the characteristics of the instrument.
During his observations, Fison used this type of instrument very often as he was the proponent of some important publications relating to the calculation of the distance between two stars.
The micrometer is made of brass and externally retains all its silvering, the mechanisms work perfectly, no lack or defects and also its original and very rare "reticular wires" are present inside.
The eyepiece wire micrometer for telescopes is made up of fixed wires parallel and orthogonal to the rotation axis of the telescope, and of mobile wires whose displacements are determined by an accurate micrometric screw. It is an accessory instrument of telescopes used to measure angular distances to celestial objects.
William and Samuel Jones were among the most successful producers of optical-scientific instruments in London in the late 18th and early 19th centuries.
In 1776 John Jones (1736/7-1808) was in business in the Holborn area, trading as an optician, his son William was an apprentice and in 1784 he entered into a partnership with his father.
In 1791 William's brother Samuel joined the company after his father's retirement and they traded under the sign of Archimedes at 135 Holborn near Furnival's Inn.
In 1793 the company drew up the auction catalog for the disposal of the magnificent collection of the third Earl of Bute.
W. & S. Jones published "The Description and Use of a New Portable Orrery" to promote their tools and describe their use.
In 1795–6 the death of another competitor, the young George Adams (son of George Adams), and the subsequent acquisition of George Junior's shares and the copyrights of his books from his wife gave another impetus to the Jones' business.
In 1797 Jones introduced the box sextant or "pocket sextant" for nautical navigation, one of the earliest marvels of mechanical miniaturization.
In 1797-1817 they supplied Harvard college apparatus.
In 1800 they moved across the street no. 30 Holborn. The company was extremely prolific, selling a wide range of optical, philosophical and mathematical instruments and apparatus in the mid-range of price and quality, as detailed in their comprehensive catalogs, published at frequent intervals.
The company continued to trade its products at no. 30 Holborn until Samuel's death in 1859.
