You are looking at two night worth of images at 200 Sec while I was after a third night clouds well and truly got in the way. This is two nights or 170 images worth of shots or 16 hours worth of data.

I have pulled all my gear ready to put in my car ready to set up on the site and run contactless from outside the tent on the field a Curtin University. There will be some 50 Telescopes on the field so viewing and some photographic like mine.

La nebulosa Dumbbell (también conocida como Objeto Messier 27, M27 o NGC 6853) es una nebulosa planetaria​ en la constelación de Vulpecula, a una distancia de 1250 al.

Esta nebulosa fue la primera nebulosa planetaria descubierta, descrita por Charles Messier en 1764. Con una magnitud aparente de 7,4 y un diámetro de 8 minutos de arco, es fácil de observar con unos binoculares.

La nebulosa Dumbbell tiene una edad estimada de 3000 a 4000 años.

La nebulosa Dumbbell, a veces conocida en español como nebulosa de la Haltera (significado del término inglés dumbbell), o bien como nebulosa de la Manzana, constituye, igual que la célebre M57, un ejemplo de nebulosa planetaria: la envoltura expulsada por una estrella moribunda. Esta fase en la muerte de una estrella no dura demasiado tiempo, por lo cual no hay una gran cantidad de nebulosas en el firmamento. Pasados 50 000 años, simplemente se disipan en el espacio.

Se estima la distancia a la nebulosa de unos 1000 años luz, lo cual implicaría unas dimensiones de entre 2 y 3 años luz para este objeto: se trataría de una de las mayores nebulosas planetarias conocidas

The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

I actually have a side panel of the Pelican Nebula that fits in, but I need 2 more panels just to complete that side and another 2 to 4 panels to get the whole complex.

Omega Centauri (English below)

Descoberto em 1677 por Edmond Halley, Omega Centauri é o mais esplêndido aglomerado globular que podemos observar. Seja pelo tamanho ou pela beleza, é sempre mágico quando Fotografamos ou observamos essa joia do hemisfério sul. Tem uma idade estimada de 12 bilhões de anos e está localizado na constelação do Centauro. Na antiguidade, por volta do ano 150 ele chegou a ser catalogado por Claúdio Ptolomeu como uma estrela.

Sua magnitude aparente é de +3,9, sendo possível vê-lo a olho nu como uma estrela débil.

Estima-se que no enxame globular existam mais de 10 milhões de estrelas e sua distância é de aproximadamente 18.000 anos-luz da terra. Tem um diâmetro estimado de 150 anos-luz.

Its apparent magnitude is +3.9, being possible to see it with the naked eye like a weak star.

It is estimated that in the globular swarm there are more than 10 million stars and its distance is approximately 18,000 light years from Earth. It has an estimated diameter of 150 light-years.

I know I want to do this again properly not just a trial shot but quite impressed how it worked out none the less. this was the camera that was faulty why I never looked at the data before right magnification though.

The Starfield GEAR 60 is a compact Quad APO with a super-wide focal length of 300mm.

I paired this little scope with a ZWO ASI2400MC Pro (color) camera and a Optolong L-eXtreme Filter.

The Heart Nebula is an emission nebula located in the constellation of Cassiopeia, around 7,500 light years away from Earth and have a radius around 165 light years.

The term ’emission’ means that the cosmic gas that forms the nebula is actually glowing itself.

Over the years IC 1805 has been designated as the ‘Heart Nebula’ due to its resemblance to the shape of a human heart.

The glow of the nebula comes from the radiation of a small open cluster of stars known as Melotte 15.

The cluster contains very young, blue, hot supergiant stars that are about 1.5 million years old and is located near the nebula’s centre. Some of this stars are about 50 times as massive as our own Sun.

The stars of Melotte 15 are blasting the surrounding hydrogen and causing it to emit light, powering the Heart Nebula’s beautiful glow.

The third attempt was the good one. Stars were weird/pinched on the first sessions (Redcat Focuser Issue).

So for the last clear night of november I decided to go back on this nebula to break the spell. :p

I've shoot from 7.00 PM to 6.00 AM, resulting in around 9.5 hours of good subs (10 min each)

Another Time, Exposure Time did the job as the Drizzle did.

This is the very last photo from the ED80 that has be retired most likely sold off or given away. I am starting the harrowing learning of using a reflector telescope. the good part the focuser and camera train are the very same as was on the ED80. I had a list of things to buy just to get the scope operational it has been a slow progress to not in stock or slow deliveries, my last part lands wednesday next week

The biggest part is learn how two line up the two mirrors so you get a photos. What I am changing to is a 200 F4 PREMIUM PHOTO QUATTRO REFLECTOR OTA its not a lens as such but all mirrors. I will be changing from a 420mm to an 800mm. This will be a while off as I get use to lining up but for the next it will be a shot from my fathers prime Nikon 85mm F1.8 D lens of Antares and the Blue horse.

the ever changing view we get of space and the things we challenge ourselves This Is a shot that took three night to get and it was hard fought with clouds. now we are in a good week plus of rain a clouds just to remind you we have our feet firmly place on this earth..

It formed by the fast stellar wind from the Wolf-Rayet star WR 136 (Bright star in the middle) colliding with and energizing the slower moving wind ejected by the star when it became a red giant.

Had to overcome a bunch of issues last night. Think I ended up imaging our neighbors pine tree at one point and had some autoguiding issues. I expected higher quality... anyway, here is Crescent Nebula after 1 hour and 35 minutes.

As my previous image NGC 6979 Pickering's Triangle,

NGC 6992 is a part of The Veil Nebula (Cygnus Loop) a cloud of heated and ionized gas and dust in the constellation Cygnus and it's a large supernova remnant. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago.The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). It's estimates distance is from 1200 to 5800 light-years from earth,

Recent clear and frosty nights have given me some decent data collection on this target. This is the Christmas Tree Cluster and the Cone Nebula (NGC2264) located in the constellation of Monoceros. The red Christmas tree shape is clear, adorned with its blue tinged open star cluster masquerading as the baubles. The Cone Nebula (inverted in this view) can be seen at the top of the image. Deep within the clouds of gas and dust are the ingredients for producing new stars, which burn a fiercely hot bright blue. The red hue in the image is a result of gas clouds glowing as they are hit by ultra-violet light emanating from the newborn stars. The region is about 30 lightyears across and sits 2600 lightyears from Earth, not far in the sky from the Orion constellation.

I got my mount back after the belt upgrade and tried the mount out. This was taken with quite a lot of moon light, such a lot of nebula's in this area. Don't even try to count the stars in this shot the number is staggering.

This is a two shot vertical panorama taken by the Nikon 300mm F4 D lens and also take on Auto focus using ZWOEAF and belt. I had to rethink the formula to work out focus for a telescope and try and fit it to a lens. the normal step size was suppose to be 125 but I cut the step size to 40 and got auto focus to work.

The mount is so much more sensitive I have had to learn how to balance again its so sensitive you have to balance with all heads loose to get perfect balance. also guiding had to be re set all the settings had to be fixed up again a lot of it turned out to be getting balance right.

In all was a very worth while upgrade can recommend it and thanks for Brendan Mitchell help to get guiding back up and running. Next it will be ED80's turn, the net result of up grade and auto focus the results look very promising.

Stay cool and enjoy Christmas with your families.
