Galaxies, Nebula, and Star Clusters

Leo Triplet Galaxies | 628 mm

Leo Triplet (M65, M66, NGC3628), three bright galaxies in the vicinity of Leo imaged with a 4 in refractor at 628 mm focal length, an ASI 533MC cooled astronomy camera, with an ASI 174MM guide camera. The trio galaxies are bright and visible with small telescopes in relatively dark skies. Two bright stars in Leo can be used to easily find this galaxy group. Imaged from a recreation site in Caliraya, Quezon, in March 2023.

Lagoon Nebula | 1200 mm

Lagoon Nebula M8 imaged with a Meade AR-6 AT (152 mm f/8) achromatic refractor at 1200 mm focal length, an ASI 533MC astronomy camera, and an ASI 174 mm off-axis guider. I used a ZWO duo nebula filter to enhance the contrast by blocking out all light except the light coming from emission nebula. M8 is visible even with binoculars or small telescopes.

Whirlpool Galaxy | 628 mm

Whirlpool Galaxy M51 imaged with a Sky-Watcher Equinox 100ED refractor at 628 mm focal length and an ASI 533MC astronomy camera. M51 is relatively bright and may be visible through a small telescope. Use the stars of the Big Dipper to find M51.

Crab Nebula

Crab Nebula M1, a supernova remnant in the constellation Taurus, imaged with a Sky-Watcher Equinox 100ED refractor at 628 mm focal length on a DIY reducer, an ASI533MC cooled astronomy camera, dual-band H-alpha and O-III filter, and an ASI 174MM guide camera. This photo was imaged and tracked using a Vixen GP mount with DIY go-to telescope controller.

To find the Crab Nebula, locate Auriga first and then scan the region south of Auriga, near the bright star in Taurus. A narrowband filter helps in increasing the contrast between the nebula and the sky (such as using a 12 nm OIII for visual use, or 6 nm dual-band OIII and H-alpha for photography). Due to the nebula’s small angular size, a telescope with 4 inch aperture or larger with relatively long focal length is recommended for this target.

Flame and Horsehead Nebula

Flame and Horsehead Nebula in the constellation Orion imaged with a Sky-Watcher Equinox 100ED refractor at 628 mm focal length on DIY reducer, an ASI 533MC cooled astronomy camera, a dual band H-alpha and O-III filter, and an ASI 174MM guide camera. Tracking was done using a Vixen GP mount with DIY controller.

Rosette Nebula

Rosette Nebula imaged with a Sky-Watcher 100ED with a DIY focal reducer, ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter. Guided tracking using an ASI 174MM with DIY Off-Axis Guider and motorized Vixen Grand Polaris mount.

To find Rosette Nebula, point the telescope to Procyon and then lock the declination axis. While looking through the finder scope and moving the RA axis only, swing the telescope westward until you see the central stars of the nebula.

Thor’s Helmet Nebula

Thor’s Helmet Nebula NGC 2359 in the constellation Canis Major imaged with a Vixen R114 reflector at 900 mm focal length, an ASI 533MC cooled astronomy camera, a dual band H-alpha and O-III filter, with an ASI 174MM guide camera. This is a very faint target that requires a relatively large telescope with long focal length to frame properly and reveal details. This target is easy to locate using the three bright stars to the east of Sirius.

Horsehead Nebula

Horsehead Nebula IC 434 in the constellation Orion imaged with a Vixen R114 reflector at 900 mm focal length, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera. The nebula is not visible in small telescopes and requires a camera sensitive to H-alpha to reveal the deep-red ionized hydrogen gas obscured by an opaque cloud of dust and gas.

Veil Nebula

Veil Nebula in the constellation Cygnus imaged with an 80-210 mm Tamron telephoto lens set at 210 mm f/5.6, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera on a 30 mm f/4 guide scope. I used the StarNet++ to reduce the stars and highlight the nebula.

Eagle Nebula

Eagle Nebula M16 imaged with a Vixen R114 reflector, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera on a 60 mm guide scope.
