It's been a while since I looked at a narrowband image, so this was fun.

The ridge of IC 5067 inside the Pelican, IC 5070, shows some excellent structures including the famous columns with Herbig-Haro 555 and its jets - most likely from an embedded protostar, all topped off with some nice dust features.

Hope you enjoy.

This is a second look at this Nebula with a whole new Camera QHY183C a replacement for the ZWOASI183MC that was faulty. I could focus automatically with this camera hence the detail in the eye is much better than the first one with the ZWO. This camera took a bit to get use to as I had to change wires and ports on the computer to get this to run and download photos.

The Orion Nebula, possibly the most photographed deep sky object in the night sky; it is also known as Messier 42, M42, or NGC 1976, a diffuse nebula situated in the Milky Way, located 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 1350 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across and it has a mass of about 2000 times that of the Sun.

C/2020 M3 (ATLAS) makes for a temporary fourth green ‘star’ in the constellation Orion’s belt in this image comprising of 47 x 2 minute and 29 x 15 second exposures taken from Grand Mesa Observatory on 11/11/2020.

 

While you’ll need a decent pair of binoculars from a dark location to see Comet C/2020 M3 with your eye, in photographs it shows up quite nicely as it photobombs the constellation Orion. Discovered over this past summer by the ATLAS telescope system, C/2020 M3 is at its closest approach to Earth today, 11/14 at about 33 million miles away.

Due to a serious case of clouditis, I decided to self medicate with a fun challenge in processing Hubble data. This here is a 6 panel mosaic in RGB. It was actually a bit of a challenge getting the panels to align and combine properly using PixInsight (18 panels in all). I definitely learned a lot as is the goal with processing these images, and I gotta say I really like the end result! Check out those little interacting galaxies at the bottom, very cool!

 

Also, who can tell me a good method for removing the halo at lower right? I don't want to just brush it out..

First light with the ZWO ASI2600MC-P and I targeted the Lagoon and Trifid Nebula region of Sagittarius using the Williams Optics REDCAT. When looking in this region, you are looking into the center of the Milky Way, our galaxy. The Trifid Nebula (blue and red nebula) is near the top and is also known as Messier 20 (M20). The Lagoon Nebula is the largest nebula in this view and is also known as Messier 8 (M8). Several star clusters are also in view including Messier 21 (M21) to the upper left of the Trifid Nebula.

 

This was also the first test using the ProAstroGear Black-CAT Mount for autofocus on the Williams Optics Redcat using the ZWO EAF, worked like a charm.

Na constelação de escorpião encontram-se uma região rica em nebulosas.

A nebulosa de emissão IC4628 está localizada próxima a cauda do escorpião.

Utilizando os filtros de Banda estreita é possível produzir uma imagem com

muito contraste, revelando nuances específicas da nebulosa, assim compondo a

conhecida Paleta de Cores do Hubble (hubble Pallette).

Essa Nebulosa possui cerca de 250 anos-luz de diâmetro e está a aproximadamente

6000 anos-luz da terra. Cobre uma área equivalente a quatro luas cheias em nosso céu.

O brilho da nebulosa se deve à estrelas jovens de grande massa que energizam a núvem cósmica,

atravéz do processo de Ionização, nas cores naturais a nubulosidade se destaca nas ondas de

cores vermelhas, devido as enormes quantidades de Hidrogênio ionizado.

My first light polluted backyard deep sky imaging attempt. The North American Nebula NGC7000 and friends using my lightweight setup. To make this all possible without leaving the house I used a powerful imaging filter. The Optolong L-eNhance blocks nearly 99% of the light pollution but allows colour cameras to capture the Ha, O3, Hb spectrums.

I was amazed at what I could tease out of 18 frames before the clouds rolled in. Plus a 70% moon🌔 📷🌌✨

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.

F.O.V. is ~7x5 degrees. Comet's tail stretched greater than 6 degrees in this uncropped image. The dust tail has also formed a wide v-wedge with several distinctive SYNCHRONIC BANDS which usually only occur with "Great" Comets.

Mid-november is almost as far as you can get from the usual galaxy season. Yet IC 342, the “Hidden Galaxy”, can be imaged all night and it’s quite a beautiful galaxy. It’s so close to the plane of the milky way that its light gets significantly dimmed and scattered by our own galaxy’s dust, so that this galaxy is effectively hidden by ours.
