AR11029 (at last!)

[daveg (Dave)]

Finally got to image this before it left the disc. Some breaks in the cloud this morning (wed - Oct 28th) so got these in the sucker holes.

H-alpha - PST-B90 @ f/15 DMK21 camera 5 pane mosaic.
White light - Celestron 100ED at f/30, DMK21 camera.

Beautiful work Dave, huge fan of your work.

[Jeffkop (Jeff)]

GREAT pictures Dave.
I think you've just solved the global warming issue too. Is it any wonder were getting warm .. Earth is getting much too close to the sun !!!!!

[Paul Haese]

Superb images Dave. Love the detail the 90mm gets. So much better than my 60mm. Time for some upgrading.

[daveg (Dave)]

Cheers Mike- Its the Sun that performs I just take pictures of the show.

Jeff - Ive often tried to visualise being that close, tellya global warming would be the least of our problems.

Paul - its just a PST box stuck on the end of my C100ED with a 90mm Baader energy rejection filter over the obj. Total cost for mod about 1500 $Aus. Next project is to get a good quality 150mm f/8 ach refractor and mod it

Being at 53N Im going to be battling solar altitude for the next few months

Great images Dave - I really enjoyed your white light - unfortunately I had no time to find the 'sucker holes' during 1029's Earth facing journey.
Thanks for keeping me in the loop!

[telecasterguru (Frank)]

Most interesting. Great images.

[dpastern (Dave Pastern)]

Wow, awesome shots. Now that's what I'd love to do one day!

Dave

[daveg (Dave)]

Matt - Sorry to hear the wx is bad. Hopefully this is only the first of many sunspots anyway.

Frank- Thanx btw I'm more of a STRATguru

Dave - Heres how to start into solar imaging.
Get a - DMK21 camera (it takes loads of frames very quickly), some Baader solar film to fit to the front of your telescope (this is the most important thing as it keeps you from being blinded by the Suns energy) and a refarctor of about 70mm upwards.
Take a video using the DMK of about 800 frames then use the freeware Registax to stack 500 of the best ones and sharpen the detail. n thats it!

Thanks Dave, I tried imaging the Sun with my own setup and a Seymour white light solar filter, shots are OK, but I found it very hard to get sharp images as I couldn't see the sunspots through my viewfinder to focus...I was doing the basic full disk image, not zooming in etc.

Dave

[daveg (Dave)]

OK - best way to focus spotless full disc is to use the edge. Keep moving in and out until edge is as sharp as possible. You may also notice some plage (white bits) near the disc edge when in focus but these, like spots and not always visible.

Of course ALWAYS post your images on IIS no matter what you think of them. The Sun can change over a matter of minutes and you may have captured something no one else has.
