Finding Old Data and having fun.

just playing with processing settings for the last M13 run – I think that this data is about 4 months old

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 !

Solar prominences from the eclipse

M31 400mm Sigma150-600 with 6D iso3200 3min subs

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.

Quiet Time

The splendour of a total solar eclipse is something that everybody should enjoy. Photographs and video do not do justice of the event

 

Wide Field M8 and M20

SO i picked up a small iEQ30Pro to manage the 6D and Sigma 150-600mm lens. The mount is beautiful and works well even if second hand. It mounts the camera flawlessly and also is able to run for 3-5 mins unguided !
