The Tulip Nebula Sh2-101
Image Description and Details:In a constellation rich in nebulae such as the Swan, there is an object commonly called the Tulip nebula. An incandescent cloud of interstellar gas and dust cataloged in 1959 by the astronomer Stewart Sharpless as Sh2-101.About 8,000 light years away from Earth, the ultraviolet radiation from the young stars on the edge of the Cygnus OB3 association ionizes and feeds the emissions of the Tulip Nebula.Near the center of the nebula there is a very bright star called HDE 227018, while in the upper right you can see an arch originating from Cygnus X-1, a microquasar, and from the star with which it shares a binary system. This is one of the most intense X-ray sources measurable from Earth, probably attributable to the presence of a black hole. Cygnus X-1 was in fact at the center of a bet between physicists Stephen Hawking and Kip Thorne, on the presence or absence of a black hole and ended in the 90s when the data reinforced the hypothesis of its existence.Shooting DataTulip Nebula Sh2-101 | Hubble Palette SHOSii 49x300'' | Ha 77x300'' | Oiii 56x300''Sky-Watcher 200/800 f/4 | AZEQ6-GT | QHY 163M | Optolong narrowband FiltersFrames captured between 26/29th of Jun 2020 from Carl Sagan Observatory in Maranello (Italy).Bortle 5 / SQM 19.65

Comet C/2020 F3 NEOWISE
Comet C/2020 F3 NEOWISE rising over Plattsburgh, New York and the Champlain Valley. I woke up early this morning and trekked to a hilltop in the Adirondacks for this capture looking toward the East at sunrise. The comet was clearly naked eye and an amazing sight. I highly urge you to check it out. Right now it is in the early morning sky at sun rise but it will be working it’s way to the evening sky and toward Ursa Major later this month. I used a Canon T5i camera with a stock 75mm to 300mm lens on a fixed tripod, with an intervalometer. The first image is at 200mm focal length and the second wide field image is at 75mm.

Jupiter Lum_IR_UV_CH4 Wavelengths Composite
Object Details:
Although I've been using various wavelengths for Deep Sky Objects (e.g. h-alpha, Oxygen III & Sulfur II), h-alpha for solar, and occasionally even 'narrowband' (e.g. DSO style) h-alpha filters for lunar and 'white-light' solar imaging (e.g. in an attempt to improve the seeing as longer wave-lengths tend to scatter less than shorter ones), I had not before tried any 'specialized' wavelength filters on the planets. Therefore, the attached composite is my first attempt to use such filters on Jupiter.
Starting with a 'normal visible' (luminance - IR/UV cutoff), from left the shots were taken using an Infrared, Ultraviolet, Methane and once again a Luminance filter. As is somewhat common, when utilizing 'specialized' filters, greyscale versions of each are included in the second row. Although Jupiter only reached an altitude of 26 degrees above our southern horizon and the seeing was fairly poor that evening, I was fortunate to catch the Great Red Spot while it was rotating on.
Generally speaking, when used on Jupiter the IR filter allows for greater penetration of the haze resulting in an enhanced contrast of small details; the UV enhances the cloud structures, while the methane (i.e. absorption) shows higher features in the Jovian atmosphere, with more methane appearing darker (and thus indicating lower) while little or no methane appears brighter (and thus indicates higher features in the atmosphere).
Image Details:
Taken by Jay Edwards at the HomCav Observatory on the morning of June 26, 2020. Being aware that the filters would attenuate the image, but not knowing to what degree, I kept the optical system used as 'photographically fast' as possible while still trying to maintain a reasonable focal length to provide some level of detail.
Therefore, the attached were shot at the prime focus of a (vintage 1970) 8-inch, f/7 Criterion newtonian reflector using an ASI290MC plaentary camera / autoguider. This scope is mounted on and tracked with a Losmandy G-11 running Gemini 2 control system.
Processed quickly using a combination of AS3, Reistax & PSP, given that these test shots turned out reasonably well, I'm looking forward to trying these filters again as we approach Jupiter's opposition next month, and if possible will add a barlow lens to increase the focal length / magnification.

Cederblad 111 (Ced 111)
Cederblad 111 (Ced 111) is a blue reflection region in the southern constellation of Chamaeleon and is part of one of the closest (~550 light years) dark cloud complexes to the Sun. Ced 110 is the bright reflection in the lower portion of the image with the distinct bright arc. Both are part of Cha I dark cloud complex. The median age is estimated at ~2 Myr. The cloud complex is a stellar nursery and many new stars have been detected through their variability and H-a emission. The small, elongated, bright red objects at the center of the image are Hebrig-Haro objects (HH 49-50), which form from a collision between ionized jets of gas ejected from newly born stars and the surrounding cloud.

Butterfly Nebula in the Sadr Region
Image Description and Details :
Now that I finally have a backyard I decided to do my first “long” project, and chose the Sadr Region to do so as it is full of gases that look great in narrowband. Living in the heart of Las Vegas, light pollution is as terrible as it gets in my backyard and the lights from the neighbors don’t help either so I aimed for 40 hours of total exposure in HSO. I ended up with 41.15 hours in total.
The image shows the bright star Sadr (mag 2.2), and part of the "Sadr Region” that includes the Butterfly nebula. Known as IC 1318, the Sadr Region is located at the center of Cygnus’s cross asterism. We can see lots of interesting gas formation within the entire photograph.

Moon occulting Venus
At 09:18 CET this morning the planet Venus was about to pass behind the Moon. Imaging this by daylight was a bit of a challenge, especially as the sun was nearby, but using a short exposure (1/100th second) and a red filter managed to capture the moment just before Venus disappeared. Image captured using my robotic telescope in Spain.

Southern Pleiades (IC2602)
Living in the southern latitudes in Australia (35d south) we are very lucky to have access to many fine clusters and objects which are circumpolar providing plenty of opportunity to grab some data.
This image is of the Southern Pleiades (IC2602) an open cluster in the constellation of Carina. It is comprised of many very hot blue/white stars which are very prominent in the image. In the left of the frame you can see another compact open cluster, Melotte 101.
Data was captured at my private observatory. Equipment: Tak TSA 120 @ F5.6, QSI683 CCD, Skywatcher EQ8 mount. Captured LRGB data for a total of 3.9 hours exposure. As much of this data was captured during a busy moon period, I took approximately 120 subs for each filter @ 30" per sub.

A Flying Bat (Sh2-129)
A Flying Bat (Sh2-129) with a Squid (Ou4) Inside?
I have been wanting to try this deep sky object for two years. It is quit interesting two objects for the prices of one. In reality I only have a portion of Sh2-129, the Flying Bat Nebula, which is a huge region of hydrogen gas represented by the red color captured with the Hydrogen gas filter (Ha). Located in Cepheus approximately 2,300 light-years away, Sh2-129 is a faint emission nebula and has been known about since at least the 1950's as a neighbor to IC 1396, the Elephant Trunk Nebula. I must admit, even after looking at widefield images of the Sh2-129, I see no resemblance to a Flying Bat. The Squid on the other hand does resemble a squid with it tentacles rapped up. The Squid Nebula (Ou4) is a relatively new discovery from 2011 by French astro-imager Nicolas Outters. It consists doubly ionized oxygen which gives it the green-blue color in contrast to the hydrogen. It may seem odd that this was not found until 2011 but there is a really good reason, it is really dim. I was taking 5-minute subs and while there was some nebulosity in the Ha region, there was nothing in OIII, not even a hint. If you are the type that likes to complete an object in one night, then this would not be a good choice.
Originally the Ou4 was thought to be a Planetary Nebula unrelated to Sh2-129, however, recent studies suggest it is within Sh2-129 and is bipolar outflow from a triple star system. The bright blue star in the center is the believed to be the source.
I wanted to get at least 15-hours and was able to get this done quicker than I anticipated due to unexpected clear weather. It worked out really well as we had a succession of clear nights when I was painting my garage floor anyway so conveniently left everything set up and just put a cover over it. This was one of the hardest things I have processed due the conflicting things going on. The Ha data was really strong and came out very well with hardly any processing. Not surprisingly, the OIII was very difficult to bring out and a lot of time was spent on it. StarNet was used to make separate starless Ha and OIII images which were combined to make a starless HOO image. The last part of the process was merging the RGB stars with the HOO starless image. This turned out be more difficult as the method I normally use for combining RGB stars with narrowband images didn't work well with the starless image so I used alternative method in PS described by Trevor Jones.

One-Armed Spiral Galaxy - NGC 4725
Image Description and Details :
While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. Here, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. The odd galaxy also sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellation Coma Berenices. Computer simulations of the formation of single spiral arms suggest that they can be either leading or trailing arms with respect to a galaxy's overall rotation. Also included in the frame, sporting a noticably more traditional spiral galaxy look, is a more distant background galaxy (text taken from NASA APOD).
Martin first imaged NGC 4725 with a CDK17/Apogee U16M but later returned to add very high quality luminance acquired with the same scope but with an SBIG STXL11002 and adaptive optics. That result is shown here, but reassembled and reprocessed using new techniques developed in Adobe Photoshop.

Cosmic Continent The Sequel (SHO)
Image Description and Details :
Several years ago I captured this beautiful region of Sky and called it “The Cosmic Continent”
Here is my latest Hubble Palette (SHO) version, a very wide view of The North America Nebula otherwise known as NGC7000 using data from Grand Mesa Observatory’s System 1a the William Optics Redcat together with a QHY16200A Monochrome CCD, this combination is giving a field of view of approximately 6 x 5 degrees
The William Optics Redcat with QHY16200A and its 7 position filter wheel is now available at Grand Mesa Observatory for subscription, see here for details.
https://grandmesaobservatory.com/equipment
In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. I removed the stars using Starnet and replaced them with the naturally colored stars from the broadband image, while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.
Captured over 7 nights in May and June 2020 for a total acquisition time of 15 hours.
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus that resembles the shape of North America and The Gulf Of Mexico. It lies at a distance of approximately 1800 light years away from us.
This image contains some very interesting areas such as The Cygnus Wall which is representative of Mexico and Central America, the nearby emission objects Pelican Nebula (IC5070) and the faint emission nebula IC5068
