M90 and its rich galaxy region in the constellation Virgo
M90 is a spiral galaxy, which draws attention and is that this galaxy is approximately 60 million light years from Earth, considering this time, the image we see now would be very close to the real image of the time of the extinction of the dinosaurs (65 million years ago).
BEST DETAILS:

Thermal emission of Venus from 8th of May 2020
Is it possible to register some details of Venus surface hidden under thick layer of clouds? – yes, it is. The answer is hidden in thermal emission of surface around 1 micron infrared wavelenght.
Attached photo which I made 8th of May 2020 with very good seeing conditions
Thanks to it I succesfully registered some nice surface detail - especially "horseshoe" shape of Phoebe Regio and dark spot of Beta Regio
Equipment:
Astrofaktoria Newton 350/14000 on NEQ-6
T7 camera (ASI120MM) + filters 950nm & 1000nm (stacked)
Exposition:
600 x 4 seconds (gain 20/100, gamma 95)

Keyhole nebula
Hi all,
Coloring was made taking in consideration real emissions of Hydrogen alfa (Ha) and Oxigen III (OIII) as captured from my observatory and combined as R=Ha, G=OIII, B=OIII.
Regarding the Homunculus, the external nebula was considered a source of Ha and consequently prevalent in red color (download/file.php?id=36961&mode=view), and the main object (globules) as a source of both emissions and was assigned a neutral, preferentially white color.

Thanks,

NGC 4382 (also known as Messier 85, M85, UGC 07508, PGC 40515), NGC 4394, IC 3292 in the Coma Berenices
12 hours exposure time to reveal the shell structure of the galaxy
Copyright: Velimir Popov, Emil Ivanov
NGC 4382 (M85) is a S0 galaxy with an interacting companion NGC 4394, which together with several other nearby galaxies (VCC 797=PGC 40512, IC 3292) form a galaxy group RSCG 54 (Barton et al. 1996). Since NGC 4382 has somewhat bluer colors than are typical for a S0, and its disk shows a spiral pattern, it is classified as a S0-a. The distance to NGC 4382 is 17.9 Mpc (58.4 Mly), calculated assuming a Hubble constant of H0 = 70 km s-1 Mpc-1 (Cappellari et al. 2010; Gebhardt et al. 2011).
The early-type galaxies (ETGs, ellipticals E and lenticulars S0) have played a central role in our understanding of galaxy evolution. Observations of high-redshift galaxies and the cosmic microwave background (Spergel et al. 2007) have revealed the Universe to be dominated by dark matter and dark energy (Riess et al. 1998; Perlmutter et al. 1999). Early-type (elliptical E and lenticular S0) galaxies (ETGs) are especially useful for observations as they are old, have smaller levels of star formation and limited amount of dust. Star formation in ETGs only happens in fast rotators and follows two distinct modes: in disks or widespread (Shapiro et al. 2010).
A shell galaxy as NGC 4382 is a normal elliptical or S0 galaxy showing faint ripples or ellipsoidal, sharp-edged features in its outer regions. Shells are likely to be 3D in geometry, not parts of a disk. Schweizer & Seitzer (1988) considered the term ‘shell’ as imposing an unjustified interpretation on the shapes of the features, and suggested the term ‘ripples’ instead. The best theory suggests that shells/ripples are remnants of a minor merger between a massive E galaxy and a small, cold, disk-shaped galaxy (e.g., Quinn 1984). In the case of NGC 4382, the fine structure appears to be “Malin shells,” which can be the result of gas-poor, primarily stellar, mergers (Malin & Carter 1980; Quinn 1984). As a core elliptical this galaxy is expected to be a mostly gas-poor merger (Lauer et al. 2007b; Kormendy et al. 2009).
Higher resolution: NGC 4382
The next image is linear stretch in B/W just to reveal the shell structure of the galaxy
The frames in LRGB filters were taken with RC 12” astrograph, f/5 in LRGB, Bin 1 at #IRIDAobservatory:
L: 21 x 20 min (420 min)
R 4 x 10 min & 5 x 15 min (115 min)
G: 3 x 10 min & 6 x 15 min (120 min)
B: 4 x 10 min & 2 x 15 min (70 min)
Total exp. time 725 min (12h)
Thank you for looking ...

M81 First light with 8" Newtonian
Last November I moved from a 19.5 SQM home to one a bit further out in the country, with SQM 21.1 skies. I also obtained a new-to-me 8" F/4 ONTC Newtonian scope, and this is the first light / first fully processed image from the new scope at the new site. The Newtonian is faster than what I was using at the previous site, and the skies are considerably darker - I can see the Milky Way again!

Three Digital Moons 2MB by Fernando Santos, en FlickrThis is a tribute to the benefits of digital imaging for astrophotography, even for simple targets as the Moon.
The first picture is a single shot (ISO200, f/6.3, 1/640s) as it could have been taken by any film astrophotographer decades ago. The second one is a stack of 32 single shots like the first one, which allows to eliminate all the interferences from the atmosphere, boosting the details and contrast of the image. And finally, basically moving a slider on any image editing software, you can exaggerate the slight colour differences of the original picture and get information about its composition, the blue parts revealing high contents of titanium in the Tranquility Sea.
The pictures were taken on May 2 - 2020, during the last Supermoon cycle in Moralzarzal (Spain).
