I haven't used my ZenithStar 61 for a few weeks and I didn't have the energy to bring out the AVX and the FLT 91.  So I settled on my smaller and much lighter rig and just spent time imaging Stars.  There are times I wish I had a reflector.

Denebola, Beta Leonis (β Leo), is a white main sequence star located in the constellation Leo. With an apparent magnitude of 2.113, it is the third (individually the second) brightest star in Leo, after Regulus and Algieba. Denebola lies at a distance of 35.9 light years from Earth. It marks the tail of the celestial Lion.

Denebola has the stellar classification A3Va, indicating a hydrogen-fusing dwarf appearing white in colour. The luminosity class “Va” indicates that it is highly luminous for a main sequence star. Its estimated age is between 100 and 380 million years.Denebola has a mass 1.78 times that of the Sun and a radius 1.728 times solar. With a surface temperature of 8,500 K, it is 15 times more luminous than the Sun. The star is a fast spinner, with a projected rotational velocity of 128 km/s. Because of its fast rotation rate, Denebola is flattened at the poles and has an equatorial bulge. Its shape is an oblate spheroid.Denebola is a suspected variable star of the Delta Scuti type. Delta Scuti variables are young pulsating stars that exhibit slight variations in brightness (less than 1 magnitude) over a period of 30 minutes to 7 hours due to both radial and non-radial pulsations. Denebola shows fluctuations in brightness of 0.025 magnitudes about 10 times per day.
Denebola and the brighter Regulus are among the 58 stars selected for navigation. They are two of the 16 navigational stars located in the equatorial region of the eastern hemisphere. Navigational stars have a special status in the field of celestial navigation because they are exceptionally bright and easy to identify. Other navigational stars in this area of the sky include the bright Sirius in the constellation Canis Major, Aldebaran in Taurus, Procyon in Canis Minor, Alphard in Hydra, Pollux in Gemini, Alpheratz in Andromeda, Diphda in Cetus, and Betelgeuse and Rigel in Orion.

The variability of Denebola was first reported in 1970 by M. S. Frolov, who included the star on the list of suspected Delta Scuti variables. In 1981, C. Bartolini et al. reported variations in brightness with an amplitude of 0.025 magnitudes over a period of 0.05 days. A study published in 1998 found evidence of a short period radial velocity variability with a period of 0.108 days.Denebola shows excess emissions in the infrared. Observations with the Infrared Astronomical Satellite (IRAS) in the 1980s attributed these to circumstellar dust. The star is surrounded by an isothermal dust shell with a temperature of about 120 K (-153° C) and a radius of 39 astronomical units from the star. The radius of the debris disk was resolved in images obtained with the Herschel Space Observatory and released in 2010. Such disks contain populations of colliding planetesimals, which supply the dust, and make the host stars candidate locations for exoplanets. There is still no direct evidence of any planets orbiting Denebola, but their existence has not been ruled out either.Denebola is a proposed member of the Argus Association (the IC 2391 supercluster), a stellar association that also includes the open cluster IC 2391 (the Omicron Velorum Cluster) and the stars Alpha Pictoris, Gomeisa (Beta Canis Minoris), and Epsilon Pavonis. These stars are not gravitationally bound, but they share a common motion through space, indicating that they formed in the same stellar nursery and were once members of an open cluster.
