From Wikipedia:
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away, with a diameter of 90,000 light years, in the constellation Ursa Major. Due to its proximity to our galaxy, large size, and active galactic nucleus (which harbors a 70 million M☉ supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also makes it a popular target for amateur astronomers. In late February 2022, astronomers reported that M81 may be the source of FRB 20200120E, a repeating fast radio burst.
Messier 81 was first discovered by Johann Elert Bode on 31 December 1774. Thus, it is sometimes referred to as "Bode's Galaxy". In 1779, Pierre Méchain and Charles Messier reidentified Bode's object, hence listed it in the Messier Catalogue.
Most of the emission at infrared wavelengths originates from interstellar dust. This interstellar dust is found primarily within the galaxy's spiral arms, and it has been shown to be associated with star formation regions. The general explanation is that the hot, short-lived blue stars that are found within star formation regions are very effective at heating the dust and thus enhancing the infrared dust emission from these regions.
It is estimated M81 has 210 ± 30 globular clusters. In late February 2022, astronomers reported that M81 may be the source of FRB 20200120E, a repeating fast radio burst.
Only one supernova has been detected in Messier 81. The supernova, named SN 1993J, was discovered on 28 March 1993 by F. García in Spain. At the time, it was the second brightest supernova observed in the 20th century, peaking at an apparent magnitude of 10.7. The spectral characteristics of the supernova changed over time. Initially, it looked more like a type II supernova (a supernova formed by the explosion of a giant star) with strong hydrogen spectral line emission, but later the hydrogen lines faded and strong helium spectral lines appeared, making the supernova look more like a type Ib.
Moreover, the variations in SN 1993J's luminosity over time were not like the variations observed in other type II supernovae, but did resemble the variations observed in type Ib supernovae. Hence, the supernova has been classified as a type IIb, a transitory class between type II and type Ib. The scientific results from this supernova suggested that type Ib and Ic supernovae were formed through the explosions of giant stars through processes similar to those taking place in type II supernovae. Despite the uncertainties in modeling the unusual supernova, it was also used to estimate a very approximate distance of 8.5 ± 1.3 Mly (2.6 ± 0.4 Mpc) to Messier 81. As a local galaxy, the Central Bureau for Astronomical Telegrams (CBAT) tracks novae in M81 along with M31 and M33.
Messier 81 is the largest galaxy in the M81 Group, a group of 34 in the constellation Ursa Major. At approximately 11.7 Mly (3.6 Mpc) from the Earth, it makes this group and the Local Group, containing the Milky Way, relative neighbors in the Virgo Supercluster.
Gravitational interactions of M81 with M82 and NGC 3077 have stripped hydrogen gas away from all three galaxies, forming gaseous filamentary structures in the group. Moreover, these interactions have allowed interstellar gas to fall into the centers of M82 and NGC 3077, leading to vigorous star formation or starburst activity there.
The top "cap" piece sits on the collar which rests on the subframe and allows the top of the bushing to pass through. The slits at the bottom of the cap engage the tracks that jut out of the collar, so the cap doesn't move when the bolt is tightened. The threaded bolt must go through the chassis opening, otherwise the bushing doesn't rise in the subframe "cup".
I always learn something new at these shows I never knew.
During the presentation after the unveiling, Kurt Hofbauer talked about the restoration process. Turns out, the engine bay of the original 1962 Chevy II, a semi-unit body with a bolt-on front subframe and engine cradle, was intended to hold either the standard I-4 or optional I-6 engines -- never a V8.
When the decision was made at GM to shove a V8 into the top-of-the-line Chevy II Nova, things were a little tight. The problem was solved at the engineering level by offsetting the entire engine slightly to the passenger side of the car. Apparently, it's derailed quite a few aftermarket and DIY 6 to V8 engine swaps, and it caused some headaches for Brian Dinsmore at Heartland Autobody in Logan, IA, who restored this car.
If you open the hood of a factory V8 Chevy II or Nova and sight down the front fascia and windshield ridges and the air cleaner wingnut, you can see the offset, even without measuring the clearances on each side.

Appearance: Red circular nebula (Bubble) inside larger molecular cloud (Sh2-161), at center of FOV. Magnitude +10; size 15 x 8 arcmin. Messier 52 (open star cluster) is at the 1 o'clock position and emission nebula LBN 537/544 (Lobster Claw) is at 8 o'clock.
From Wikipedia:
NGC 7635 (also known as the Bubble Nebula, Sharpless 162, or Caldwell 11) is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star BD+60°2522 is thought to have a mass of about 44 M☉.
With an 8 or 10-inch (250 mm) telescope, the nebula is visible as an extremely faint and large shell around the star. The nearby 7th magnitude star on the west hinders observation, but one can view the nebula using averted vision. Using a 16 to 18-inch (460 mm) scope, one can see that the faint nebula is irregular, being elongated in the north south direction.
Messier 52 (also known as M52 or NGC 7654) is an open cluster of stars in the highly northern constellation of Cassiopeia. It was discovered by Charles Messier on 1774. It can be seen from Earth under a good night sky with binoculars. The brightness of the cluster is influenced by extinction, which is stronger in the southern half. Its metallicity is somewhat below that of the Sun and is estimated to be [Fe/H] = −0.05 ± 0.01.
R. J. Trumpler classified the cluster appearance as II2r, indicating a rich cluster with little central concentration and a medium range in the brightness of the stars. This was later revised to I2r, denoting a dense core. The cluster has a core radius of 2.97 ± 0.46 ly (0.91 ± 0.14 pc) and a tidal radius of 42.7 ± 7.2 ly (13.1 ± 2.2 pc). It has an estimated age of 158.5 million years and a mass of 1,200 M☉.
The magnitude 8.3 supergiant star BD +60°2532 is a probable member of the cluster, so too 18 candidate slowly pulsating B stars, one being a Delta (δ) Scuti variable, and three candidate Gamma Doradus (γ Dor) variables. There may also be three Be stars. The core of the cluster shows a lack of interstellar matter, which may be due to supernovae explosion(s) early in the cluster's history.
Its an Innocenti Mini, which I think came along round about 1985. It was basically a BLMC Mini upon which the Italian Innocenti company placed their own body designed by Bertone (or was it Bert and Tony!). It comprised front and rear mini subframes, floorpan, but the mechanicals were all mini. It also came with two sizes of engine 998cc or 1275cc Leyland "A" series. Although I bought mine already converted to RHD, they were fairly easy to do. You needed a RHD Mini Mk2 steering rack and had to move the pedal box and brake master cylinder to the RHS of the car. This was fairly easy also as the body had identical holes on both sides of the front bulkheadb to facilitate this The fascia was symetrical, so you could swap instrument pod and glove box to either side of it.
I bought mine from a dealer who specialised importing RHD Metros from mainland Europe to the UK, which was quite popular at the time. They had seen these Innocenti Mini's running round in Belgium, brought three back to the UK and converted them to RHD to see how they sold.
Mine had the 1275cc engine with the biggest SU carbuerettor I have ever seen. I had assumed it was a Mini 1275GT engine, but was actually told later by an expert, that it was a Mini Cooper engine. Be that as it may, I took it onto the A64 bypass and floored the throttle. It got up to about 102mph, which is a bit disconcerting when your backside is only about six inches off the road.
The door locks were surprisingly of Alfa Romeo manufacture, phew, that was a surprise, but a relief when I eventually realised this, after losing my keys. It only had one niggling fault and that was the fact that the engine would run on after switching off. I fiddled around with ignition timing and fuel mixture, to little avail, so in the end I decided to live with it. Rather than switch the engine off, I used to stall it on the clutch.
With the birt of our third child in 1988, it was obviously too small, so I sold it to a Mini Cooper enthusiast, who lived in Malton.
