Image Description and Details : With only 2 months left to complete 10 years of the ghost crater discovered by me, I present a new photo in better resulution of the formation in question and take the opportunity to transcribe the original text with some minor adaptations."I've always had the greatest interest in astrophotography of Lunar formations and from the beginning, using mainly the Virtual Moon Atlas, I tried to find and know the most striking features of the regions I observed or photographed.As time went by, I acquired a better knowledge and more easily recognized these regions and their main accidents, which greatly facilitated the perception of anything that clashed with the traditionally observed landscape.So on January 5, 2012, photographing the region near Plateau Aristarchus, I noticed a strange depression that caught my attention. I tried to locate it on lunar maps and even in the Virtual Moon Atlas, but I found nothing.I searched the internet, asked for help from colleagues in Brazil and abroad to clarify what this training could be, I believed that it should already be known or that others had already observed it.In principle, I couldn't find any reference to this lunar formation.Looking at the attached photo, the impression we have is the existence of a depression that is only revealed when the Sun is at a very low angle of illumination.I sent the original photos to my friend Vaz Tolentino from the Lunar Observatory (VTOL) back in 2012 and he gave me the following explanation: Indeed, your photo, due to the angle of sunlight, captured an interesting and unusual circular depression, which has along its southwestern rim, the crater WOLLASTON D (5km in diameter). The formation is very strange in that it doesn't look in the style of known ghost craters. The strange and unusual thing is that, it appears that the supposed crater was flooded by basaltic lava and, instead of filling up and leveling off with the surrounding outer floor, it only filled a little and didn't even out, remaining like a "gourd" or "bowl ", in addition to leaving no traces of a central peak. This depression appears to be about 42 km in diameter, being slightly larger than ARISTARCHUS. I checked LRO images and unfortunately I can't identify anything due to the sunlight being high in the photos. We need more photos of this region, in light conditions similar to the one in this photo.At Alexandre Amorim's suggestion, I decided to contact BAA (http://www.baalunarsection.org.uk/) Lunar Section where I made contact with Dr. Anthony Cook. I sent to the same the photos obtained by me in January and June 2012, as well as I reported the suspicion that the referred depression had not yet been catalogued. After exchanging several emails, I received the following message from Dr. Cook, which I transfer in full:On Mon 4/06/12 07:06 , "Tony Cook [atc]" atc@aber.ac.uk sat:Dear Avani,Thank you for your images. It looks like a buried ghost crater that you have found. Please keep on looking for another ghost craters elsewhere on the Moon because I think that there may be quite a few that are visible near to sun rise or sunset that remain to be discovered. I think this work will be of great interest to Peter the Greek.

Dr Anthony Cook Institute of Mathematics and Physics, Aberystwyth University, Penglais, Aberystwyth, Ceredigion. SY23 3BZ. United KingdomIn April 2013 using the new QHY 5L camera, a color CMOs dedicated to high resolution Lunar and planetary photography, I got a more detailed photo of the place where the depression was located:This allowed colleague Vaz Tolentino to trace the altimetric profile of depression and perform the following analysis:"Dear Avani and Amorim:Analyzing the Avani photos (January/2012 - April/2013), together with the altimetric profile that presents a classic phantom crater depression, I reach the conclusion that, most likely, it is the discovery of a new phantom crater without cataloging.Also analyzing the altimetry of the ghost craters DAGUERRE, LAMONT and that discovered by VTOL in February 2011, I came to the conclusion that they have very similar altimetric profiles, and the Avani ghost crater is a little shallower (46 km of diameter per 130 m depth) than DAGUERRE and LAMONT (both approximately 400 m deep).However, Avani's ghost crater depth (130m) is more compatible with the ghost crater discovered by VTOL (which is approximately 100m deep). What this means?It means that, in the past (at the time of the ancient selenographers), when the main interest in observing the Moon was to map its relief, identifying and naming its formations, they did not have the current technology, that is, shallow formations like these two Phantom craters (Avani and VTOL) are very difficult to see through an eyepiece, to be sure of what you are actually looking at.After the initial period of cataloging and naming relief formations, lunar map drawings and other studies, the space age arrived. The first robotic lunar probes (Soviet and American) and the manned landings of the APOLLO missions had other scientific goals than discovering new, uncatalogued formations. Furthermore, even in the very high resolution photos taken by modern robotic lunar probes (SELENE, LRO, GRAIL, etc.), the images were mostly captured with sunlight coming from above and not obliquely, which makes it difficult relief enhancement and does not facilitate the identification of shallower formations such as these phantom craters.For modern selenographs, only after the technological evolution of digital cameras (CCD and CMOS), together with the evolution of telescope optics (large and good mirrors and also APO lenses), combined with the favorable angle of incidence of light on the lunar surface, it became easier to identify new smaller formations, "camouflaged" and not cataloged on the Moon.Congratulations Avani Soares on your discovery!Another point marked by the new generation of Brazilian selenographers. A hug from the VTOL team!In this way, I believe that any misunderstanding regarding the existence and identification of the aforementioned training is ruled out, only lacking the official disclosure and recognition to crown the aforementioned work."

NGC 986 is a barred spiral galaxy in the constellation of Fornax, located about 56 million light-years away. It is a small target and is not imaged often. The galaxy contains two large, extended and slightly warped arms that begin at each end of the central bar.

Young blue stars are spread through the arms and the core of the galaxy glows with star formation surrounded by numerous dust lanes.

Image Description and Details : The Fish head Nebula (IC1795) is a star forming region in Casseopeia, and part of the Heart Nebula Complex. Often seen as an appendage in wide field shots, close up it has some fascinating dust lanes, back lighting and reflection as well as emission components.
Its relatively close to Earth at 6000 light years. This image is shot in SHO ( Hubble) Palette and is full frame ( no crop) at 2650mm Focal length.

I shot this over 4 nights about two weeks ago on my Planewave CDK14 out in the New Mexico desert.

This was my first test of 15 min unguided sub shooting on the Planewave mounted on an L-350 mount. I was able to use about 80% of all subs.

Image Description and Details : Here is a rich field located within the large molecular cloud of Cepheus.
This image was an experiment under my downtown sky, and i am rather happy with the result because, although having probably approached the limits of the Bortle 7 sky, it shows that urban astrophotography still offers possibilities with this type of object.

4 types of nebulae are visible in this image, against a background of nebulosities of interstellar dust:
- the dark nebula Barnard 175, a dense pillar of dust
- the reflection nebula Vdb 152, shining a characteristic blue at the top of this dark pillar
- the old planetary nebula DeHt-5 radiating mainly in the wavelengths of ionized hydrogen and oxygen (red and blue)
- part of the SNR 110.3 + 11.3 supernova remnant whose ionized hydrogen filaments (red) cross the field

Some distant small galaxies are visible in the background despite the density of this area of ​​the Milky Way.

Image Description and Details : Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars from even the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident.

Two techniques were used to get this image: framing selection and downsampling. I chose only about 65% of the frames that I actually shot, removing bad signal from out of focus, cloudy, or polluted frames. I also downsampled the image by 50% increasing snr and the amount of dust I imaged.

Image Description and Details : First "official" photo of our team Team Stellae Orientis Astrophotographie with the Perseus molecular cloud in LRGB by Yann SAINTY.

The Perseus molecular cloud contains the nebulae NGC1333 and IC348.

First lights on the fsq106 and the 2600MM and the result is up to my expectations. Combined with a bortle 4 sky this setup promises beautiful moments.

No moon so I wanted to image NGC1333 but seeing the beauty of IC348 next to it I could not resist the appeal of the mosaic despite the fact that it was not recommended during a first session with a new setup.

I imaged over 2 nights instead of 4 (lots of humidity and fog), which frustrates me in the sense that I only got half of the raws I wanted and so I had to shoot more processing. as desired, but you have to know how to have fun and try things!
