W.O FLT110 focuser upgrade

The Feather Touch FTF3025 Focuser from Starlight Instruments, is a major upgrade from the stock W.O focuser.
Replacing the original focuser on my FLT110 with the Feather Touch unit required about 5 minutes.
The fit and finish of the Feather Touch was something that had to be used to be appreciated!!!

Crater Petavius

Petavius is a large lunar impact crater located to the southeast of the Mare Fecunditatis, near the southeastern lunar limb. Attached to the northwest rim is the smaller crater Wrottesley. To the southeast are Palitzsch, Vallis Palitzsch, and Hase. Farther to the north is the large crater Vendelinus. Petavius appears oblong when viewed from the Earth due to foreshortening.

The outer wall of Petavius is unusually wide in proportion to the diameter, and displays a double rim along the south and west sides. The height of the rim varies by as much as 50% from the lowest point, and a number of ridges radiate outwards from the rim. The convex crater floor has been resurfaced by lava flow, and displays a rille system named the Rimae Petavius. The large central mountains are a prominent formation with multiple peaks, climbing 1.7 kilometers above the floor. A deep fracture runs from the peaks toward the southwest rim of the crater.

NGC 7635 Bubble Nebula Hubble palette

full resolution

60% of the original size

NGC 7635, also called the Bubble Nebula and Sharpless 162, is a H II region[2] 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[2] magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).[7] 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.[7] It was discovered in 1787 by Friedrich Wilhelm Herschel.[6] The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

M15 Globular Cluster

60% of the original size


full resolution


Messier 15 or M15 (also designated NGC 7078) is a globular cluster in the constellation Pegasus. It was discovered by Jean-Dominique Maraldi in 1746 and included in Charles Messier's catalogue of comet-like objects in 1764. At an estimated 13.2 billion years old, it is one of the oldest known globular clusters.

M15 is about 33,600 light-years from Earth. It has an absolute magnitude of -9.2 which translates to a total luminosity of 360,000 times that of the Sun. Messier 15 is one of the most densely packed globulars known in the Milky Way galaxy. Its core has undergone a contraction known as 'core collapse' and it has a central density cusp with an enormous number of stars surrounding what may be a central black hole.[citation needed]

Messier 15 contains 112 variable stars, a rather high number. It also contains at least 8 pulsars, including one double neutron star system, M15 C. Moreover, M15 houses Pease 1, one of only four planetary nebulae known to reside within a globular cluster, which was discovered in 1928.[1]

To the amateur astronomer Messier 15 appears as a fuzzy star in the smallest of telescopes. Mid to large size telescopes (at least 6 in./150 mm diameter) will start to reveal individual stars, the brightest of which are of magnitude +12.6.

NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes or is near the open cluster IC 1590, the double star HD 5005, and several Bok globules. It is visible in amateur telescopes from dark sky locations. It is sometimes unofficially referred to as the Pacman Nebula owing to its fancied resemblance to the eponymous hero of the arcade game Pac-Man.

The Dumbbell Nebula (also known as Messier 27, M 27, or NGC 6853) is a planetary nebula (PN) in the constellation Vulpecula, at a distance of about 1,360 light years.
This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes.

These are the typical CCDInspector2 results with the SBIG ST10XME camera used on the FLT110 OTA with TMB dedicated field flattener.
These examples were taken from an imaging session of M27 through the Baader Planetarium luminance filter.
The results show a very flat field.The sensor size is 14.9 x 10 mm with 6.8x6.8 microns pixels.

The CCDInspector2 from CCDWare is a wonderful program!!!!

NGC 6823, NGC 6820 Open cluster and nebulosity in Vulpecula

NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula.

The most striking feature is the trunk-like pillar or dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. Remarkable dark globules of gas and dust are also visible in the nebula, much as is seen in the better known Eagle Nebula in Serpens or the Lagoon Nebula in Sagittarius.

Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away.

M106 is at a distance of about 22 to 25 million light-years away from Earth
Messier 106 (also known as NGC 4258) is a spiral galaxy about in the constellation Canes Venatici. It was discovered by Pierre Mechain in 1781.It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.[7] NGC 4217 is a possible companion galaxy of Messier 106.[6]
