"updated" have a play with my first HA image.

[xtreemchaos]

have a go, its raining with no clear insight. heres the Tiff staxed 100.tif.

its the best 100 frames that's been sorted with PIPP and staxed with regi. it would be good to see what others can get outa my image.

this is what it looks like.   thanks for looking.   clear skys charl.

Wow,lots of fine detail there!

One day I will get some H-alpha gear. I love the whorls and vortices.  I would be very happy if this was my first capture.  

What equipment did you use ?

 

Sean

[xtreemchaos]

thanks Iain, it could do with sharpering and a bit of colour, theres more detail there but I keep going over the top and making it all noisey. clear skys, charl.

[Ibbo!]

have you tried AS2 to stack it?

[xtreemchaos]

thanks Sean, sw ed80 scope, Quark chromo, 50% reducer, baader ir filter, asi120mc cam. took 1200 frames avi with firecapture, sorted the 1200 frames with PIPP down to 100 best frames and staxed with registax 6. I'm amazed with HA, ill hopefull get to do a mosaic soon. clear skys, charl.

[xtreemchaos]

thanks Steve, I don't seam to get on with autostacker, mainly beacase I find regi staxed better when there was cloud in the frame, ive got it on my pc, ill have to give it another go.  clear skys , charl.

[Craney]

Ahh...the Quark Chromo.   That looks a nifty bit of kit.   Would you recommend it ?  Those dedicated H-a scopes above 60mm are the realm of oil barons and Russian Oligarchs.  Did you agonise over the decision to go 'Quark' ?

[Ruud]

Congratulations! This is a great first result. Very good!

[xtreemchaos]

thanks Sean, ive only imaged one session so far, and ive never tried a lunt solar ha scope, but I'm well impressed with it. the Quark I have is on loan from a friend, but ill deff be getting one. charl.

[xtreemchaos]

thanks Ruud, beginners luck mate, clear sky ,charl.

[Owmuchonomy]

Hi Charl seems like you have the Ha bug. ? I would have a go at your image but a 100 frames is a bit light hence your noise issue. Aim to stack 600 at least. Also, your image looks sharpened already? To be honest I find Registax to be a bit of a sledgehammer. AutoStakkert is much better at stacking my Ha stuff.

[Stub Mandrel]

Hi Charl, this is using Astra Image to sharpen, denoise, multi-scale contrast then colour up a bit. Then the gradient got rid of in Photoshop using Gradient Exterminator and the colour sorted out again (gradex made all the dark bits blue!)

I wish it was as easy to get good results with my own data!

[johnfosteruk]

Well I had a go and although I couldn't get too much more out of it due to the noise, it's an image and it's had some processing so it'll do me 

Main things were a touch of wavelets, adjusted the gamma and contrast in Registax. Then tried to muck about with an artificial flat to take out the gradient and colourising obviously.

Having no Ha gear, while doing this I learned that you can push the sharpening quite a way with Ha, interesting, must look into securing some fundage.

thanks Chris, will be redoing in the morning with Autostacker, dont think I could pullout 600 frames from my 1200 frame vid 5.7gb but maybe I could do 100 to 150 more frames so it might help, could get any longer vids with fast moving cloud, I usally do 4000 f vids. clear skys, charl.

[xtreemchaos]

nice one Neil, you have pulled a fair bit more out of it, like the colour. well done, charl.

[xtreemchaos]

thanks John, looking good mate, the noise is a pain , but ill try and get more frames next time, I'm going to have another go in the morning with AS. well done,  charl.

[Davey-T]

Some strange vertical artifacts if you zoom in, maybe from stacking, as mentioned try AS2, works for me, sometimes have to edit out dodgy frames using Virtual Dub before they will stack properly.

Dave

 

[xtreemchaos]

thanks Dave, didn't notice them mate, ive had similer when doing moon close ups but never that narrow,ill see if I get them with AS tomorrow. clear skys , charl.

[xtreemchaos]

update, thismorrnig ive rePIPP it with 350 frames converted it to bnw and saved to ser, staxed with AS2 and ive ended up with lines running the whole top to bottom 10 times worse than regi but over all if you don't zoom in I think its a nicer image with AS. id pull me hair out if I had any. any ideas chaps ?.

 

[Stub Mandrel]

My guess is that because Ha is so narrowband, it's only affecting the 'R' pixels and confusing the debayering?

perhaps if you do 2x23 binning?

[Davey-T]

As Neil says, looks like the bayer matrix, didn't spot that you were using a colour camera though other folks are using them without problems as far as I'm aware.

Have an experiment without the focal reducer and also try a barlow to see if it affects the result, when / if the Sun appears.

I'm sure the long suffering Mrs Chaos won't mind buying you a mono camera if you explain your technical problems 

Dave

[xtreemchaos]

thanks Neil and Dave, ive got the misses lined up for the Quark . sounds like you have hit the nail on the head, with also having problems with moon shots aswell when convert to bnw.

ive done another vid this was taken without the reducer, but the lines are there but not as bad , its staxed the same with AS.

   

[Davey-T]

Much better Charl, can't see any lines.

I've found using focal reducer or barlow or none of the above has strange effects imaging with the Quark, nothing noticeable visually so must be camera related.

Dave

[xtreemchaos]

agreed mate, I think we have made progress, I nearly binned that last vid because it didn't look good enough when taking it with the seeing at hi mag, at the mo I'm reprocessing the one I took with the reducer and not converting to bnw to see what happens also trying binning as Neil said, ill update my findings as soon. charl.    

 update, woops AS wont stax colour, back to the drawing board.
