Near NGC3079 is the twin quasar (PGC 2518326) lies at redshift z = 1.41 (8.7 billion ly). "The Twin Quasar (also known as Twin QSO, Double Quasar, SBS 0957+561, TXS 0957+561, Q0957+561 or QSO 0957+561 A/B), was discovered in 1979 and was the first identified gravitationally lensed object. It is a quasar that appears as two images, a result from gravitational lensing caused by the galaxy YGKOW G1 that is located directly between Earth and the quasar".

Continua la mia nuova esperienza con la camera raffreddata ZWO ASI533MC-Pro. In questa occasione volevo testarla insieme al filtro dual-band Optolong L-eNhance 2", molto utile nelle riprese di nebulose in caso di siti con Inquinamento Luminoso a LED.
A inizi di giugno la Via Lattea è anora molto bassa, quindi ho scelto le prime nebulose osservabili, anche se molto bassi visto che dalle mie latitudini si mantengono sempre sotto i 20° sopra l'orizzonte, quindi con più Inquinamento luminoso e meno trasparenza.
Non avevo idea del possibile risultato. Invece devo dire che il filtro L-eNhance ha fatto il suo lavoro tagliando molto inquinamento luminoso così da evidenziare le nebulosità.
Naturalmente, trattandosi di un filtro passante solo per la banda H-Alpha (rossa) centrata a 656 nm e attorno alle vicine linee di emissione OIII (azzurre) e H-Beta, le immagini prendono tendenzialmente con dominante rossa così pure le stelle di altro colore perdono la loro colorazione RGB. Inoltre in questo caso specifico essendo la zona fotografata molto bassa la luce deve attrversare uno strato di atmosfera maggiore, che filtra i colori che vanno verso il blu (quello che succede al sole durante il tramonto).Nei limiti del possibile ho tentato di equilibrare soprattutto le stelle.
Mi ritengo soddisfatto anche perchè da casa senza una camera raffreddata e un filtro a banda stretta non avrei mai potuto raggiungere questo risultato.

___________________________________________________
My new experience with the ZWO ASI533MC-Pro cooled camera continues. On this occasion I wanted to test it together with the Optolong L-eNhance 2" dual-band filter, very useful when shooting nebulae in the case of sites with LED light pollution.
At the beginning of June the Milky Way is still very low, so I chose the first observable nebulae, even if they are very low given that from my latitudes they always remain below 20° above the horizon, therefore with more light pollution and less transparency.
I had no idea of the possible outcome. Instead I must say that the L-eNhance filter did its job by cutting a lot of light pollution so as to highlight the nebulosities.
Naturally, since it is a filter passing only for the H-Alpha (red) band centered at 656 nm and around the nearby OIII (blue) and H-Beta emission lines, the images tend to be red dominant, as are the stars of other colors lose their RGB coloring. Furthermore, in this specific case, since the area photographed is very low, the light must pass through a greater layer of atmosphere, which filters the colors that go towards blue (what happens to the sun during sunset). To the extent possible I tried to balance above all the stars.
I am also satisfied because from home without a cooled camera and a narrow band filter I would never have been able to achieve this result.

This frame is another mixture of frames taken with dual narrow band filter and without such filter. I changed balance of them. I made wide band frame far stronger in this version, though the exposure was not enough. I believe long exposure at dark site essential.
Hydrogen-alpha emissions were rich here.

Abell 35 es una nebulosa planetaria visible en la constelación de Hidra .
Se observa en dirección a la constelación de Corvus , a unos 4,5° al este de β Corvi , al sur de Virgo ; se puede fotografiar con telescopios de media potencia. El período más favorable para su observación cae en los meses comprendidos entre marzo y julio, aunque desde el hemisferio norte , debido al aumento de las horas de luz vespertina, su observación se ve penalizada; por el contrario, desde el hemisferio sur es más visible.
Es una nebulosa planetaria ubicada a una distancia aproximada de 160 pársecs (522 años luz ) del sistema solar ; en su centro se encuentra una variable cataclísmica conocida como LW Hydrae , una estrella binaria compuesta por una enana blanca , responsable de crear la nebulosa, y una enana blanca-amarilla de la secuencia principal de clase espectral G , separadas por unas 13 UA .

This is a HOO blend of H-alpha and O3 narrowband subs. The NB filters were the Optolong 7nm H-a and 6.5nm O-III, in a QHY CFW2M-US in front of a QHY163M camera.The scope was a William Optics FLT110 with Flat4, mounted on a Skywatcher AZ EQ6-GT. Imaging was managed via Sequence Generator Pro with PHD2 for guiding and autofocus enabled via a Lakeside Astro motorized focuser.
All post-processing was done in PixInsight and the image is a stack of 109 x 2 minute H-alpha and 65 x 2 minute O-III subs.

5 minutes x 18
everything that could possibly go wrong went wrong with this image. Firstly the object is too low, just barely clearing my roof, if not actually grazing it; secondly I got the spacing wrong -pure operator error so poor star shapes in the corners; thirdly I corrected the spacing without thinking that I hadn't taken flats so had to fall back on synthetic flats; fourthly synthetic flats can help reasonably with vignetting but are less effective with dust on sensor.
If today were not a cold wet rainy and miserable day I probably wouldn't have bothered processing the data at all.
Oh well

Eindelijk weer eens wat aan astrofotografie kunnen doen. Niet moeilijk, maar lekker met een klein lensje en de gekoelde 2600mc.

I was trying to test my new Optolong L-Extreme filter with a full moon. Unfortunately, clouds rolled in at the 50 minute mark. I was going to scrap the data but ended up playing with it for a bit and ended up pulling out enough for an image.
I first processed it bringing out the reds a lot more but decided to make it a bit more subtle instead. Not bad for such minimal data.

Faint green circular light is surrounding the planetary nebula, though it may be of reflection optical ghost. There look three dark belts probably due to shadow of four vanes at the entrance of the reflector optical tube assembly. A band of shadow is missing. I will image the object again with a suitable APO refractor telescope.
