ok i have had a hack at the data - and towards the later part of the transit i suffered from droopy scope, wind, clouds and user errors but i made the most it i could. the BF1200 is stuffed and that is the root cause of all the evil dust bunnies....... (http://youtu.be/iLBYAUYMj7Y)it will be replaced in a few weeks:question:

Dave, you might be disappointed but I think it looks fantastic and you have captured a piece of history. Well done.

Nice work Dave – I hope that the 159 GB Mountain is slowly but surely being ascended and that the summit is nigh…
13-06-2012, 06:46 AM
Very cool, Dave!

thanks guys - all that was killing me was the bf1200 filter (http://www.iceinspace.com.au/forum/showthread.php?t=91015&highlight=lunt)

I superb piece of work Dave regardless of the dust bunnies.

Agree, A very fine result David, A credit to the work you have out into it, well done :thumbsup:
13-06-2012, 12:37 PM
Awesome Dave, well worth the trip my friend (brother..?) :thumbsup:
13-06-2012, 01:13 PM
thanks Trevor - its something i set myself as a goal way back in 2004 at that tranist
i could have processed the images better but i lack the skill set just now - maybe over the next 100 years i can learn :rofl:..
Mike it was an experience that i wouldnt have missed. I learnt lessons for the solar total eclipse and also that even with basic gear, impossible odds and a fair amount of luck its possible to image. Also I still cant turn a average image into something desireable:rofl:

Thats great Dave, it's the only TL I've seen of this and it's excellent.

Thanks Fred I appreciate that thought
thanks a lot:thumbsup: Narayan

I wondered if anyone would do a timelapse... and yours is a definitive answer.
Some technical quibbles, but hey, you stayed on target for 6 or hours...not an easy task! Nice to watch :thumbsup:
13-06-2012, 08:03 PM
thanks for looking Peter. yes there are more than the odd quibble, but then thats what makes it unique;) (I keep telling myself that). I have to say that without Mike being there pushing the buttons it would have been even more a daunting task. Nature calls :lol:

Dave thats very good.
Stuff venus - I've had a great time watching the sun slowly turn, replaying this one over and over. Any imperfections lost in the magnificence of it. Thanks David.
13-06-2012, 11:01 PM
there is stuff happening all over this - from proms to sunspot movement. I have another 300 odd video files to process so i will be redoing this again at some time:thanx:
14-06-2012, 08:15 AM
That's avery cool time lapse. Well done. :thumbsup:

Fantastic stuff, in the HD version I can clearly see some solar features in motion, some surprisingly quick too.
14-06-2012, 05:40 PM
That's a wonderful sequence! You have really brought out the active regions nicely, I wanted to get the same sequence myself. Could I ask how you went for tracking? And what software did you use to capture your AVI's? As you might be aware I have a vested interest in guiding and sequencing etc.
14-06-2012, 06:19 PM
thanks Scott. currenltly processing the white light filter shots the same way, but have nearly 850 images to do
Well tracking is a bit of a sore point - we had it close but i forgot to lock the dec bolt - it shifted when we checked the filter was secure - with a crack!. so was hand guided after that - for the whole event. did have solar rate selected. the dmk capture software was used, manually set everything and pushed button to record
14-06-2012, 06:57 PM
Despite your BF the result is very good - hope you can get it sorted!
15-06-2012, 06:18 AM
apparently the new BF 1200 filter will be sent from the US for the replacement to fix the diagonal
15-06-2012, 10:59 AM
That came up very nicely, considering the technical challenges, i also have not seen many time lapse clips. the detail is all there well done :thumbsup:
16-06-2012, 10:44 PM
i finished my timelapse sequences Brad see here (http://www.youtube.com/watch?v=-uOo_bK7LoM)
16-06-2012, 11:07 PM
That Ha one is a beauty your efforts are appreciated.
16-06-2012, 11:10 PM
Nice work Dave well worth the trip
16-06-2012, 11:18 PM
Derek I took over 400 30 second shots. i haven't processed them all yet - some will work and some wont due to wind and other movements but what i tried to do was cover the event in the Ha in 3 min increments for the video (though i took 30 second shots all thoughtout), though there were a few technical difficulties resulting when i tried to meridian flip - i had to put it back the way it was and image through to the finish - we quickly tested to see if the gear would slew through to the finish without hitting the mount - just jagged that one as well. I will redo the video again after i learn to process Ha shots better and process the backlog
16-06-2012, 11:21 PM
thanks Al - it was indeed - one for the age....
17-06-2012, 12:19 AM
Now thats the good gear..........well done very nice sequence
Fabulous stuff David!
Bet somebody comes out with a remake though in 105 years time.
17-06-2012, 02:18 AM
And I wished I will be here to see it. Lol
