LocationDerry NH USA
EquipmentDSI Pro II behind 10" LX200R @ f10
DescriptionAfter years of trying to capture and blend with hours of luminance data, the wispy H-alpha filamentary structure flaring out orthogonally from the distorted disk of this enigmatic object, as if to compete with Hubble and others in their amazing images, I decided to abandon the layering and masking and blurring then masking and multiplying and dynamic range masking and stacking and yada yada yada, in favor of a natural look. Some may say that M82 is no beauty contest winner in the Universe pageant but I marvel at her so.

Locationnear Bolu, Turkey
Date3rd December 2007
EquipmentFor the main shot showing both objects, I used a 100-400 mm lens at 400 mm f/8, with a Canon EOS 5D camera at ISO 1600 and an exposure of 4 minutes, piggybacked on a Meade 8" LX10 SCT. Then I composed two pictures of both objects separately taken with the 8" SCT. For NGC253, it was an exposure of 1 hour at ISO 800. For NGC288, it was a shorter 10-minute exposure at ISO 1600.
DescriptionNGC253 is a bright, large spiral galaxy lying about in the faint constellation Sculptor. It is the brightest galaxy in the Sculptor with the magnitude of 7.1; with the distance of 10 million light years. NGC288, on the other hand, lies only 27000 light years away, in the halo of Milky Way. It is a magnitude fainter than NGC253: 8.1. The pair is separated 1 3/4 degrees of sky. They are visible in the same binocular field (about as wide as this picture) but most telescopes are not able to fit them in the same field. South Galactic Pole (SGP) lies less than a degree soutwest of NGC288, close to the lower right corner of this picture.

EquipmentTelescope: Orion ED80 on Skywatcher EQ5 Synscan mount Camera: Canon 350D
DescriptionThis huge cloud of dust dominates the far south sky as seen from a remote mountain site in Mendoza, Argentina. It is crossed by several dark lanes composed of obscure material and giving the nebula its beautiful appearance. Is no doubt that Eta Carinae Nebula is one of the finest telescopic objects visible from the south hemisphere.

EquipmentFSQ106N refractor, SBIG ST2000xm camera, Takahashi NJP mount
DescriptionIC 443, the Jellyfish Nebula, a galactic supernova remnat approx 5,000 light years distant, in the constellation Gemini. Imaged over 4 nights on Jan 12-13-14-15, 2008. Imaged with FSQ106N and ST2000xm (Astrodon Filters) riding on the Takahashi NJP. 200 minutes of Ha was used for the luminance, 100 mins of SII for the red channel, 200 min of Ha for the green channel, and 100 mins OIII used for the blue channel (all unbinned, 20 min subs).

EquipmentImaging scope was Orion ED80 Canon Rebel XT - Hap Griffin Modified 18 x 300s Guided with PHD & EQMOD DSLR Focus V3, IRIS, PS CS2 WO 0.80 Reducer / Flattener & IDAS LPS
LocationPalmela in Portugal country
EquipmentTelescope: William Optics APO. refractor FLT110 (F7). Mount: Losmandy G11 with Gemini (go to). Camera: SBIG ST2000XM with wheel of filters CFW10. Filters: Astronomik narrow band filters (H-alpha, SII, OIII) Programs for processing: Maxim DL and Photoshop CS2. Without darks and or flats.
DescriptionTimes of expose: (H-alpha)-2x60minutes. (SII)-1x60minutes. (OIII)1x60minutes. It used the Hubble palette where the H-alpha filter was used as luminance and with the green color, the SII filter with the red color and finally the OIII fiter with the color blue. This nebula is located in the Orion constellation and distant from our solar system 6400 years light.

DescriptionPart of the eastern half of the Veil Nebula, it is directly south and basically attached to NGC 6992.The filamentary structure is composed of mostly hydrogen gas, with enough oxygen III to provide a pretty green counterpoint to the red hydrogen alpha emission
