Hi Guys! My name is Daniel and I am from Ecuador, I love astronomy and the secrets our universe holds. I love Jupiter, our big brother, so I opened this forum to talk about facts, secrets, theories, etc. About our gas giant!

A very crisp and cold night. I added more luminance data and also collected some RGB for NGC 2841. There is now around 4 hours in L and an hour each in R, G and B. The subs are 114s at a gain of 139. Wikipedia: NGC 2841 is an unbarred spiral galaxy in the northern circumpolar constellation of Ursa Major. A 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined its distance to be approximately 14.1 megaparsecs or 46 million light-years. This is the prototype for the flocculent spiral galaxy, a type of spiral galaxy whose arms

Mosaic of the Large Magellanic Cloud One of two (known) companion/satellite galaxies of the Milkyway galaxy, located 160,000LY away and only visible from the southern hemisphere. Due to the angular size of the LMC, this image consists of 4 frames, each exposed in natural color at 500mm focal length through an 80mm refractor. The 4 frame are combined into one image to fit the whole satellite galaxy into the frame. The camera used was my astromodded and active cooled canon 40D. Exposure time was 2 hours and 42 minutes per frame for a total of 11.5 hours for the whole image.© Mariusz Goralski

NGC 6357 is a nebula about 5500 light years away in the constellation Scorpius near the better known NGC 6334, AKA the "Cat's Paw" or "Bear Paw" nebula. This nebula was also given the name War and Peace Nebula because of its appearance in infrared images, the bright western part resembles a dove and the eastern part looks like a skull. This photo was taken through a 8" SCT at f6.3 (1280mm focal length) and exposed using a full spectrum modded and cooled Canon 40D DSLR.© Mariusz Goralski

This is a close up of IC 2944, also known as the Running Chicken Nebula or the λ Centauri Nebula, with the Bok Globules visible in the upper third of the frame. IC2944 is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. This image was exposed using a Cooled and full spectrum astro modded DSLR through a 8" SCT at it's native 2032mm (f10) focal length. The total exposure time was 8 hours and 25 minutes, through a UV/IR filter to capture natural colour data.© Mariusz Goralski

Hi, This video is intended to be for someone who is thinking of buying their first scope but isn't sure which one is best. I would love it to be a good jumping off point for discussion and I hope some wise heads will wade in and answer questions and offer alternative opinions. Thx to astrostace and helena's astro and deddy dayag for contributing. I fear I'm going to have my head down making my next video as I'm currently astrobiscuiting full time (or at least till my loan runs out!). So all help much appreciated. https://youtu.be/Na-aBhc_gTY

As the poor weather and short nights are limiting my observing projects, I have been busy finishing a heavy duty aluminium and stainless steel parallelogram mount for my large 100mm APM binoculars. Here is a summary description of its build: http://refreshingvie...rammount.htm�.� It has been derived from a wooden version that I built last summer. I plan to give away the wooden model to a fellow SPOG astronomer who wants to do some bino observing while his camera is capturing photons on the scope. The parallelogram mount is an extremely comfortable to observe the night sky – the eyepieces rea

ngc 253 John Herschel in South Africa ( NGC 253, Sculptor Galaxy )
MikeODay posted a blog entry in The Sculptor Galaxy - NGC 253
Sir John Herschel at the Cape of Good Hope Having spent the years 1825 to 1833 cataloguing the double stars, nebulae and clusters of stars visible from Slough, in the south of England, John Herschel, together with his family and telescopes, set sail from Portsmouth on the 13th of November 1833 bound for Cape Town. As detailed below, in an extract from his book, the family enjoyed a pleasant and uneventful voyage and arrived some 5 months later at Table Bay with all family and instruments in good condition. Reading on however, one might very well think that it might not have ended so-

Observations of the Sculptor Galaxy ( NGC 253 ) by William and John Herschel ......... Part 2. Observations of "Caroline's Galaxy" by Sir John Herschel, 1830's Sir John Herschel, the only child of Mary Baldwin and Sir William Herschel, was born in 1792 when his father was in middle age and already famous as one of world's leading astronomers. Having excelled in school, and no doubt inspired by his famous elders, John Herschel decided upon a career as a 'man of science' and set out to pursue a wide range of interests; with one particular focus being a continuation of the

Observations of the Sculptor Galaxy ( NGC 253 ) by William and John Herschel The very large and bright 'nebula' discovered by Caroline Herschel in 1783, that we now know as the Sculptor Galaxy, was observed a number of times by her 'dear brother' Sir William Herschel and by her 'beloved nephew' Sir John Herschel, Baronet. Some of these observations were recorded and published in the Philosophical Transactions of the Royal Society and, with respect to those by Sir John in South Africa, in the book of Astronomical Observations at the Cape of Good Hope. .........

The Discovery of the Sculptor Galaxy by Miss Caroline Herschel in 1783 On the 23rd of September 1783, sitting before her telescope in the field behind the house she shared with her brother William in Datchet near Slough in the south of England, Miss Caroline Herschel "swept" the sky searching for new comets and never before seen star clusters and nebulae. On this occasion, way down in the sky, not far above the Southern horizon, Miss Herschel saw and noted down a very bright and large nebula where one had never before been recorded and that was later recognised by her brother, Sir Willi
