M27- The Dumbbell Nebula, is a planetary nebula in the constellation Vulpecula. Planetary nebulae have nothing to do with planets. They are low to intermediate mass stars (1-6 times the mass of the Sun) in their death throes. When the nebula dissipates, a white dwarf star remains.
M101 is a grand design spiral located about 20 Mly away in the constellation of Ursa Major. To locate it find the handle stars Mizar and Alcor and move to the east as shown in the attached chart.
M16, the Eagle Nebula, is an HII region (ionized atomic hydrogen) in the constellation Serpens. About 5700 ly away, it is a region of active star formation. The famous Hubble space telescope "Pillars of Creation" are in this nebula (seen centre of this image).
M67 is an open cluster in the constellation of Cancer. Located about 2700 ly from Earth, it is a rarity amongst open clusters in that it is relatively old, on the order of 3-4 billion years old. Most open clusters are generally less than a billion years old.
M8 - The Lagoon Nebula - is star formation region located in the constellation of Sagittarius. It contains many Bok globules (some of the small dark clouds inside the nebula) where the dust and gas are collapsing to form stars.
The galaxy M63 appears in the optical as a flocculent spiral, that is a spiral galaxy that doesn't really have well defined spiral arms. It is about 29 Mly away in the constellation Canes Venatici.
NGC 7217 is a spiral galaxy located about 50 Mly away in the constellation of Pegasus.
The Horsehead Nebula is an example of a dark nebula. We see what looks like a horse's head because it blocks the light from the emission nebula that is behind it.
A preliminary image from the tests with the @RAOastronomy Baker-Nunn telescope on Friday. Colour suppled by using theatrical gels as filters. The green spikes are an imaging artifact from the green gel. 1 minute each in LRGB.
If you missed the live streamed telescopic earlier, here's a link to the recording: https://youtu.be/GTS6v9vtFGU

Time to start getting set up for tonight’s live stream.
At 19:00 Mountain Standard Time I will be attempting another telescope live stream. I'll post the link at that time.
