A (false) color image I made of Messier 51, using the iTelescope network and the SalasJ editing program.  Messier 51 is made up of two galaxies, M51a- the Whirlpool Galaxy and M51b also known as NGC 5195.

Did you know: all color images from telescopes are “false color” images?  Telescopes only take pictures in black (no light) and white (light).  Pictures are taken using different wavelength filters then each filter is assigned to a color- red, green or blue to create a color image.

M42 The Orion Nebula

This images was taken on iTelescope T8, a Takahashi FSQ 106mm scope coupled to a FLI microline camera. It is comprised of Luminescence, Red, Green and Blue exposures, each of 5 minutes. The FITS files were first processed in ESA’s Fits Liberator before processing in Photoshop CC. 

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

Small Magellanic Cloud by Alan Tough Via Flickr: This 6-frame mosaic was captured remotely using iTelescope T12 at the Siding Spring Observatory, New South Wales , Australia. Total imaging time was 114 minutes through Ha-LRGB filters.

M45 Pleiades (Luminescence)

Also known as The Seven Sisters, Pleiades is on open star cluster that is easily visible by eye in the night sky. This image captures 2 of the main stars on Pleiades, the one at the top of the image with the three bright stars beneath it is Alycone. Alycone is  a B5IIIe (a Blue Giant) star with a surface temperature around 12258K. It is approximately 3.5 Solar masses and has a radius approximately 8 times that of our Sun. The other star located with this cluster is towards the bottom left and is called Merope. Merope is a B6IVe (a Blue Sub-Giant) with a temperature around 10395K and a radius 4.71 times that of the Sun.

The image was taken using iTelescope T7 located in Spain, it is a 300s luminescence exposure.

NGC 253 - The Sculptor galaxy

This is a 20 combined LRGB (4 x 300s) exposure with the opacity of the luminescence frame set at 33%, I don’t think it dissolves any colour from the image at that level.

The Sculptor Galaxy is located at the centre of the Sculptor Group, one of the nearest groups of galaxies to the Milky Way. The Sculptor Galaxy (the brightest galaxy in the group and one of the intrinsically brightest galaxies in the vicinity of ours, only surpassed by the Andromeda Galaxy and the Sombrero Galaxy[) and the companion galaxies NGC 247, PGC 2881, PGC 2933, Sculptor-dE1, and UGCA 15 form a gravitationally-bound core near the centre of the group. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core. NGC 253 is about 11.4Mly away.

Messier 39 - Wikiwand

Messier 39 or M39, also known as NGC 7092, is an open cluster of stars in the constellation of Cygnus, sometimes referred to as the Pyramid

M33, the Triangulum Galaxy, is a member of our local neighborhood, including: The Milky Way, Andromeda and Triangulum. All are within three million light-years.

I photographed M33 using remote telescope T5 at the New Mexico Skies Observatory on October 9, 2018.

The star cluster NGC 3293 is at the centre of this photo, but the setting is the spectacular Carina Nebula, a vast complex of glowing gas and dust lanes at a distance of 7,000 light years in our galaxy . I photographed NGC 3293 using remote telescope T12 situated at the Siding Spring Observatory in Australia on August 6th - 9th. #itelescope #itelescopenet https://www.instagram.com/p/BnRlQ7xFLAa/?utm_source=ig_tumblr_share&igshid=10v6ir2txa6ws
