Rosette wide field

so was trying something different last night — would have loved to have the scope setup but that was not to be. So here is 120 mins spent imaging the Rosette with the Sigma 150-600 at 200mm f5.6.

Pleiades with Flux

The Pleiades is one of the most famous asterisms in the sky with the stars closely grouped and naked eye visible emission nebulae. Known by many names its a beautiful target for the telescope. However, the images through telescopes miss one of the most important parts of the nebulae — The Flux…

M45 with IFN

The image above starts to show the Flux network which covers most of the sky but is very very faint. The intergalactic dust which is very faint in the image does cover most fo the sky but is very difficult to image in other regions. The image itself is a short run 7 images at iso 1600 with Sigma 150-600 at f5.6

Lunar Eclipse

Sunday the 20th saw what was termed the super wolf blood moon …. or just another larger (not noticeable) moon and a lunar eclipse. The wolf moon name comes from native north Americans who called the moon a wolf moon as you could hear the wolves howling at this time of year.

After a period of cloud — lasting about 3 months ! we had a clear day and night but Ontario was gripped into a polar vortex with real temperature at -22C and the “its cold feel like temp” at -40C it was going to be a challenge to capture on film….

Well after a significant cold time — multiple hours the final blood red was not that red ! the image below is a HDR composite of a series of bracketed exposures

Comet 46P and Pleiades

The comet 46P flyby which was to be the closest comet approach for years. This was occurring on the evening of the 16th of Dec and for the first time on about 2 months it was clear. The moon was fairly large on this day and the sky was a little washed out.

Initially the sky was clear and we setup cameras etc but soon after it started to cloud. after waiting for the cloud to clear it did indeed become very clear and the sky was very clear.

the below is a composite of 10 x 60s at ISO 1600 and 180mm using a Canon 6D and a Sigma 150-600mm lens. the images are dark, bias and flat corrected.

Milky Way @ Manitoulin

Had to finish of the images from the trip to Manitoulin. These are both parts of the milky way and composite of multiple sub frames both are shot with a Canon 6D and Sigma 12mm f2.8

The Bubble…….

I have been trying a new processing method for the processing of the images. This was 3 hours of images from Manitoulin each of 10 min subs and processed against 15 x 10 min darks. The image was taken with the FLT 110 and guided. The image was processed by preprocessed by dark subtraction alignment and integration. The integrated image was then split into RGB channels and each was processed individually. Once desired levels were set the image was recombined.

Comet P21 in M35

after a terrible issue with due the challenge is always is there enough time for anything else. here is a few short unguided images of the comet 21p in M35 from 15/09/18

which is best ? both of the same object different days and different conditions.

both images are of the cocoon nebulae taken on different days and with different settings — one image is a series of 10 min exposures for 3.5 hours and the other is just 1 hour integration of 2 mins exposures.

The Middle of the Milky Way

So the weekend has been spent in manitoulin and basically turning nocturnal. Friday after the drive was supposedly going to be foggy and it was believed that the probability of of an imaging would be minimal. Instead the skies cleared and the night was very very long. Friday night i images 1 hour on the cocoon as an experiment to test against the longer imaging session, The Cave nebulae for 4 hours and 10 minutes of the 21P comet. Besides the CCD I have east mid and west Milky Way data, and data for this image. the region encompasses the M8 and M20 objects as well as Saturn in the image. Saturday night was a long night imaging just one object more on this once i have new dark calibration frames. 

First Telescopic image of 2018……

so it has been a very slow year with the lack of clear nights and also lack of desire to take the scope out.

 

this is 3 hours of data from the FLT with the SBIG taken from Tiny. The colour balance is a little off here and the lack of the rudeness which i have gained before is strange.
