This is the view I was after when the USB plug broke on the camera March last year. This proved to be a marathon getting images as the mount threw up a curveball and at this stage still not sure if I have found the answer to the problem.

 

This will be my last photo for a very long time as I do a huge panorama of the Milky way of some 40 odd shots. Enjoy it.

A target I did a year ago with my DSLR and ED80 this is almost the other way around ZWO camera and 300mm Prime Nikon lens. the original shot give a good idea just how far in a year thing have improved. The Camera and lens rotated within the lens holder so the wings went from side to side across the whole picture. The next project is a wide field of the same area with 100mm lens.

I was trying out some new equipment when I thought I would try Carina as it was over head. At one point I had to go inside the smoke was so strong and the Guiding got very bad. Only the Second shot I have done that was almost totally edited in PixInsight never see the amount of nebulocity around the main nebula. the mount stopped as the house next door got in the way enjoy the Southern hemisphere at 900mm.

The name of this one how could I resist. Has been a cloud fight to get the shots over 4 night in very strong winds. this sits just below the Horse head nebula and just off the red ring that goes around Orion.

Luna 19 May 2013.

 

I was determined to try my first real session of astrophotography using my new telescope last night, but a failure to correctly polar align, as well as incoming clouds put an end to that idea.

 

I did however manage to observe saturn which was amazing, and of course Luna.

 

This was taken prime using a Canon 1000D (baader modified) through my Skywatcher 200P-DS. I need to get a 2" barlow :)

 

P.S It makes a lovely iPad mini homescreen image :)

The Perseus double cluster complex imaged during a brief period of clear weather on night of 9th October. Consisting of two open star clusters NGC869 (top) and NGC884 (below) the complex lies at a distance of around 7500 lightyears from us.

 

Both clusters contain hot white and blue-white comparatively young stars as well as some supergiant red ones. These red/orange stars are more numerous within NGC884.

 

The clusters are physically close in space and are believed to contain at least 300 hot-white and blue-white super massive, super-luminous, giant stars in each cluster.

 

Conditions were not great with clouds coming and going with variable transparency on Saturday night. Eventually fog and mist moved in calling a halt to my imaging session and I had to trash a number of exposures.

 

Imaged with my little Skywatcher 72ED refractor with flattener and a ZWO ASI2600MC camera.

The images I take with my Skywatcher AZ-GTI mount raise many questions about how I can use this ALT/AZ mount for astrophotography.

 

I recently wrote an article about the topic that should answer most of these questions. You find it under:

After cloud cover all day a brief unexpected clearance last night allowed me to image the waxing moon.

 

The moon is approx. 85% illuminated and the brightest area of the moon, the crater Aristarchus, is nicely contrasted within the gloom of the lunar terminator. (LHS)

 

The subtle colour variations within the moon's surface are also nicely revealed.

 

My small short focal length refractor, a Skywatcher ED72, was already mounted and I attached it to a Nikon D5300 DSLR to capture this image.

The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.

 

It a complete rework of a previous image made on SHOrgb.

A total of 57 hours of integration and a lot of intermediate version on the process.

 

Still I think that I could obtain more details, but this will be next year (maybe :P ).

Part of an HII (ionized Hydrogen) region in Cassiopeia the Pacman Nebula is a bright emission nebula.

 

Named for its resemblance to the video game character the nebula lies at a distance of around 9500 light years from earth.

 

This image captured in narrowband Ha light was acquired over 2 nights - 17 & 18th September in strong moonlight. After a prolonged period (seemingly never-ending!) of poor skies was glad to be out imaging again!

 

Hopefully will have some OIII and SII to add later.

Second completed image of 2021 and the first complete one from my local astronomy club's dark site, an hour and a half outside of Houston. We finally had the first clear new moon weekend of the year, and myself and many others in the club decided we had to take advantage of it. It was a beautiful night with no clouds and the dew kept at bay. Had to image something unique for galaxy season and I settled on Markarian's Chain in Virgo. I framed to to get as many individual galaxies as I could in one shot.

This is a pretty cool area in the constellation of Auriga. You have just about everything going on here; emission nebulae, reflection nebulae, dust clouds, star formation, open cluster, young and old stars. This nice astrophotography target passes almost straight overhead near the zenith during the winter months.
