So it seems that the only options i have at the moment is to use the long lens and the DSLR…. Maybe one day i will be able to get the telescope out again – thats if the weather ever lets up. So this shot is 180 30 second exposures taken with a 6D on a iEQ30Pro with a Sigma 150-600 @ 400mm and f5.6 The data was processed in Pixinsight with automatic processing.
So its been a really painful winter period. The cloud has been terrible and the skies just ….. After all of the winter i have managed to put together my final wide field for Orion and after processing it looks I have finally pulled out the Barnards loop. Hopefully its time to get the scope out and start on the galaxies which are high in the sky at the moment.
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…..
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.
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 !
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
