Astrophotography

Wide field witch

So with so few nights in the last few months its been desperation time to get out 🙂 The last time out decided to hit the witch head nebulae. This is a diffuse region to the west of Rigel . Also known as NGC 1909 this is a reasonable size and a DSLR is likely the best option to catch it. Also the image which was a series of 3 min exposures will need more data likely step up to 5 mins and maybe increase ISO this was shot at ISO 800…..

Attempts for a comet with wide field

So the winter is a time to enjoy the skies when you can and get out the only problem is that in Ontario that can be a little cold ! But there is a strange comet in the sky so is it possible to image with a DSLR and a standard lens?

We’ll at 50mm in a Sigma 24-105 lens on a 6D i really think that the answer is no ! Image was taken on Jan 14th at 8pm it is a composite of 10 x 3 min images. It is very very faint but i know where it is.

Besides the comet i will be back to this area of the sky again as the dark neb in the top left is very interesting….. 

First for 2018 ……

SO its been a significantly long period of time before posting again here ! The winter this year has been brutal not many clear nights and those that we have had have been just far too cold to function or on full moons.

The second January thaw is here and the snow is receding at the moment but this probably won’t last long — One good thing is that the snow mobile trails are closed so we could be out with telescopes if it was not cloudy !

So for the first post of the year i will add a reprocess from the summer this is the point of totality it is a HDR composite of a number of different frames and shows nicely the chromosphere around the sun — seen like a life time ago since August !

IC1396 Elephant Trunk nebula complex

So i had wanted to try this for some time but the time has just slipped by. The Sigma Lens at 500mm should have been able to pick out the complete system but the whole setup was not very stable that night and all that was achievable was a 1 min sub frames — how ever i managed to take 240 of them at ISO 12800 — maybe a little too high !

So here is the result — its faint but the level of the dark nebulae is amazing

 

the elephant trunk is visible as shown in the this crop 

M13 with a near full moon and a cold night !

Images of M13 taken on the same night and with the same setup just double integration in the second series of the images

image taken with 5 min sub exposures and 5 images taken

image taken with 10 min sub exposures and 10 images taken

 

The images are of really good quality with very sharp focusing. this was somewhat a surprise as the quality of the sky was very poor with high levels of moisture present.

a zoomed region of the core shows the complexity as well as the colours of the different stars present.

So it takes lot of coincidences to make the most of the weather !

IT HAD TO BE CLEAR! There needed to enough dark and enough time without work! and there had to be a small moon (although it is at 1st Quarter.)

 

When all of those items come together then its Telescope time !!! If only the bugs knew to remember this fact

Image a couple of objects here is the first on this is a 25 min combination of the Lagoon M8. A series of 5 min Subs were used and stacked in Pixinsight etc.

 

 

 

 

NGC7000 new mount and big lens

so here is a quick shot of NGC7000 from last night. 5 x 3 min at 300mm f5

Aurora and moving skies !

here is a very long time lapse from last night 22nd April 2017

 

 

 

More Aurora Another movie from the other night — it really never gets boring.

 

First M42 of the year ……

OK So M42 ids this years big project hopefully with a wide field and burners loop. But i wanted to know what the state of play is with the 150-600mm lens and the 6D. So here is a single 30s exposure of the M42 region at 600mm tracking (not very well) ISO3200
