Times For Emerging Crescent Moons
Below are times for viewing Crescent Moons in UT for Dublin, Ireland. Crescent data is specific for your location but adding your timezone offset from GMT to the Sunset and Moonset times will give you an idea of when the Moon is visible locally. The amount of time you have to see a crescent and what percentage of the Moon is illuminated will be somewhat different for where you live. LunarPhase Pro will calculate all this information specifically for your location. The data in the screenshot below was generated by the software.

What Messier Objects Are Visible This Month (October, 2026):

A list of messier objects visible this month. All are possible with binoculars, most are easy even with small binoculars.

As summer turns to fall we complete our tour of the wonders in Sagittarius. Sixteen Messier objects are found within the constellation of Sagittarius, we will seek the six that remain to be seen on our tour. We will also search for three others just north of Sagittarius in the Milky Way. Our October tour includes two nebulae and the clusters that power them, four open clusters, a star cloud, and lastly two globular clusters. All of these objects are possible in binoculars, most are easy in even small binoculars. Several of these are also possible naked eye objects.
M24 This "object" is actually a section of the Milky Way in Sagittarius. It is easily seen with the naked eye as a fuzzy, oval patch about four times the size of the full moon. The best views are through binoculars or rich field telescopes.
M25 Just east of M24 in Sagittarius we find this open cluster. Visible to the naked eye, M25 lies in the same binocular field as M24. In binoculars it appears as a partially resolved star cluster buried in faint nebulosity. A view through a telescope shows the nebulosity is in fact many faint stars that are not resolved in small instruments.
M18 This is a small open cluster just north of M24 in Sagittarius. In binoculars M18 is easy to see as a small fuzzy patch of light in the same field of view as M24. Telescopes reveal this cluster for what it is, a small, sparse collection of fairly bright stars.icult binocular object, look for a small fuzzy patch of light. Through a telescope M14 is an even patch of light, the stars not resolvable except through large scopes.
M17 Just north of M18 and in the same binocular field as M24 and M18 lies the Omega nebula. Possible to see with the naked eye and easy with binoculars, this nebula appears as a small faint patch of fuzz. A telescope will show the unique V shape nebulosity that gives the cluster its name. The shape reminds me of a swan with two bright stars that power the cluster embedded in the head and neck of the swan.
M16 Continuing north of M17 we find another nebula in Serpens. To the naked eye and binoculars, this small patch of haze is very similar in appearance to M17 which is in the same binocular field of view. Through a telescope the M16 looks like a sparse open cluster of stars surrounded by faint wisps of smoke.
M26 Continuing to head north through the Milky Way we find this open cluster in the constellation Scutum. This is a difficult object to find in binoculars, but possible as a faint patch of fuzz. Telescopes partially resolve this cluster and show several stars buried in a faint glow from the unresolved stars.
M11 Just north of M26 in Scutum lies the Wild Duck Cluster. Possible to see with the naked eye, binoculars show a small faint patch surrounding a bright star. Telescopes resolve many of the stars in this very rich cluster.
M55 Dipping back into Sagittarius we find two more globular clusters waiting for us. The first is one of the brightest and largest globulars in the catalogue. Possible to see naked eye, it is an easy binocular object appearing as a bright fuzzy ball of light. Telescopes show a round patch of light bright in the center and fading toward the edges. Large aperatures are needed to resolve this globular.
M75 The last object of the month, and the last object to be visited in Sagittarius. In binoculars, M75 is not too hard to see, look for a small fuzzy star. A telescope will show a small fuzz ball with a bright center.

Satellite Predictions and Visibility
Spot The Station
NASA SkThus web-based application provides sky watchers worldwide with a picture of when and where the International Space Stationcan be seen with the unaided eye as it passes overhead.

Heavens Above
Provides all the information you need to observe satellites such as the International Space Station and the Space Shuttle, spectacular events such as the dazzlingly bright flares from Iridium satellites as well as a wealth of other spaceflight and astronomical information.

Online Skymaps and Charts
Your Sky
An interactive planetarium run by Fourmilab. You can produce maps for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet. A control panel permits customization of which objects are plotted, limiting magnitudes, colour scheme, image size, and other parameters.

Daily predictions for brighter satellites (Heavens Above)
Provides a range of charts and information, including sky charts for your location (which you’ll have to specify).

  1. I was wondering if you know what the light that streaked across northern Illinois Dec 7 2011 at around 10:40 – 10:50 PM was?
    My daughter and I saw it while driving on interstate 57 N just past Champaign. She thought it was a shooting star but this light was very bright colorful and just too big (or close?) to be a shooting star. I have never seen anything like it. Has anyone figured out what it was?
