Arcturus

Arcturus’ bright light was used to open the 1933 World’s Fair in the host city Chicago, Illinois (USA). Back then, people thought Arcturus was 40 light years away from Earth, so it was chosen to go along with the 40th anniversary of the previous Chicago World’s Fair in 1893.

August's full moon goes by a lot of names, including the Sturgeon Moon, the Green Corn Moon, the Raksha Bandhan Moon, Nikini Soya, and the end of the Esala Perahera festival.

It is called the Sturgeon moon because during this time of the year, there is supposed to be lots of sturgeons out swimming around. Here is a link to some more information:

I was able to get to see some of this year's Draconid meteor shower (*1.), it was a bit different. Usually the meteors I get to see have longer lasting bright flashes as they come whizzing down out of the sky, these tended to be less colorful, but still very neat to see.

Auriga The Charioteer. This constellation usually shows up in the Northern Hemisphere during the late fall, early winter months. Its shape is easy to recognize and with its mainstay star Capella being so bright, it is easy to find.

Welcome, dear visitor! As registered member you'd see an image here…

(constellation stars are listed in red, DSOs are listed in green.)

Auriga is itself home to lots and lots of DSOs (deep sky objects --- various kinds of nebulas, galaxies, star clusters, etc.) one of these is IC 405, the Flaming Star Nebula:

This is the equivalent of a 30 minute exposure.

Orion is easily recognizable once you know it is there. Orion's Belt is probably the famous part of the constellation, but there is more to the star show than these three twinkling lights. Below the belt (below the left most star -- Alnitak) is Orion's Sword. The sword is usually visible even in light polluted skies, while you need darker skies to see Orion's Bow. The sword contains beautiful nebulas and star clusters.

Big Bear Rising.

Ursa Major, some call her The Big Dipper or The Plough (according to Greek mythology, Callisto was turned into the big bear and put up in the sky to roam around. One of the usual tales of jealousy.)

https://nineplanets.org/ursa-major-constellation/

https://en.wikipedia.org/wiki/Ursa_Major

On a seasonal note, during the Northern Hemisphere's winter months, Ursa Major tends to stay low in the northern sky, always just above the horizon. Somewhat like a bear hibernating. And like a bear, in the springtime it will shake off winter napping and climb up out of its den. Once you see it rising in the sky above the light dome (light dome is a polite term for the light pollution around cities and towns) spring is not too far away.

Mintaka

Welcome, dear visitor! As registered member you'd see an image here…

Simply register for free here – We are always happy to welcome new members!

Mintaka is the star on the top right of Orion's Belt (Alnitak, Alnilam and Mintaka). Steady and stolid, it is not part of nebulae and things like that, but without it, Orion would not have much of a belt. When you look up at the constellation, it looks like Mintaka is a single star in a dark part of space, but there are actually several stars orbiting around each other.

https://www.star-facts.com/mintaka/

https://nineplanets.org/mintaka-δ-orionis/

This is the equivalent of a thirty minute exposure.

Bode's Stuff

 

Welcome, dear visitor! As registered member you'd see an image here…

Simply register for free here – We are always happy to welcome new members!

M81: Upper Right

M82: Lower left.

Messier Object M81 is named Bode's Galaxy after Johann Elert Bode, the German Astronomer who found it in 1774 along with the very nearby M82. Originally, it was called Bode's Nebula, but after folks took another closer look, they realized it was a galaxy. Still, the name Bode's Nebula stuck around and today the two names are interchangeable.

https://www.messier-objects.com/messier-81-bodes-galaxy/

https://www.nasa.gov/feature/goddard/2017/messier-81

 

Messier Object M82, also found by Johann Elert Bode in 1774, is called the Cigar Galaxy. It is bright enough and large enough to see using binoculars, usually during March and April.

https://www.messier-objects.com/messier-82-cigar-galaxy/

https://www.nasa.gov/feature/goddard/2017/messier-82-the-cigar-galaxy

Edit: added 20 minutes of additional exposure time to the M81 section to show some more definition in the dust lanes.

This is the equivalent of a seventy minute exposure (fifty minutes for the M82 part).

edit: I framed this shot a little differently. So this is a new image.

Mineralized Worm Moon

Welcome, dear visitor! As registered member you'd see an image here…

Simply register for free here – We are always happy to welcome new members!

The moon shines so brightly that it seems there is no color there, just bright reflected sunlight. Not even green, if you recall that the moon is made of green cheese. 😀. Actually there is a lot of color, one technique called 'Mineral Moon' brings it out. NASA has an example: https://www.nasa.gov/multimedia/imagegallery/image_feature_819.html

March's full moon is called The Worm Moon, on account of the soil warms up and the worms crawl out. Worm Moon goes by quite a few other names:  https://www.timeanddate.com/astronomy/moon/worm.html

Messier Object M3 is a globular cluster of all kinds of different types of stars.

https://www.nasa.gov/feature/goddard/2017/messier-3

https://www.messier.seds.org/m/m003.html

This is the equivalent of a 48 minute, 20 second exposure. If the skies are dark, you can see this one using binoculars, or a small telescope, or, if the skies are really dark and you have pretty good vision, you can just look up and see it (if you look in the right place).

Hercules Cluster M13 (84 minute equivalent exposure).

From a dark place, you can see this one in the northern sky just by looking up. Of course, having more than 100,000 stars in the cluster helps brighten it up a bit.

    • Hi Members Do we have a database of fuji lenses and their reviews somewhere in this forum? I remember from my pentax days long ago on the pentaxforum, there is a lens database where it holds the specs, reviews and sample photos and a rating scale on several factors like sharpness, bokeh etc., connected to that particular lens. So was curious to see if something in that line exists. Another - can anyone share a link to comparison between XF 23mm f2 and XF 27mm f2.8 if you have come across on something like that.
    • Looks like a falsely applied perspective correction.
    • I've had some... not success but definitely a slight improvement playing with different metering modes. Changing the ISO range had no effect. Not sure what you're suggesting with the bulb setting and external timer. That's just going to be fixed exposure length of what 1/2 second? I've got a similar timer that I've used with a Sony in the past and it doesn't allow for exposure ramping. I realise there are timers that do, but even then exposure ramping isn't exactly what you need for HG because it's not a linear transition over time.

      The M48 to X-Mount adapter with lens cap. The focuser. Loosen the three (screws / bolts) and remove the inner part. Inner part removed and some M48 extension tubes are added to the adapter. Just use long enough extensions for the focuser to hold onto the combination but not so long that when you put them into the focuser, it hits the secondary mirror. That will cause a lot of bad juju. (The small mirror at the top of your Newtonian is called the secondary). Adapter combination attached to my trusty X-T10. Slide the tube into the focuser, tighten the (screws / bolts) and you are good to go.
    • The shorter M48 to X-mount adapters are usually the ones that work. The trick with Newtonians is that the focus spot is almost inside the focuser. Edit: I am updating this portion, the older stuff that was here is still valid, but 'a picture and a thousand words and all of that'. If you look at the focuser closely, you see it has the outer part and the inner part sitting inside. Loosen the screws on the outer part, take the inner part out of the focuser and slide in the adapter with the camera attached. Tighten the screws and adjust the focuser as needed. The overall “trick” is to find the scope specs listing for what is called back focus (for many refractor scopes it will be 55mm, but for reflector scopes it will be very different depending on what kind of scope it is, rc scopes have very different back focus distances than do Newtonians than do …) Okay, Fujifilm X-mount cameras have what is called the flange distance (the distance from the mount spot to the sensor in the body) of 17.7mm. If your scope or accessory has a back focus of 55mm, subtract 17.7 from 55 to get 37.3mm that you need extension tubes to cover. Most Newtonians have very short back focus distances, so you almost need to have the camera inside the focuser. Other bodies, Canon, Sony, Nikon, etc. with deeper flange distances are more troublesome when trying to use them with standard Newtonian scopes. Edit: It occurs to me that I could hopefully make this a bit clearer by demonstrating with one of my scopes, so in a bit, I will post that and not rely on looking at other sites for visuals. I will try to do so quickly and come back and edit this posting. HTH.
