Popular Post StuartJPP Posted May 2, 2016 Popular Post Share Posted May 2, 2016 I posted an image last month of M81 & M82 that was only ~1 hour's worth of total exposure time. On Saturday night/Sunday morning I managed to get another 3.5 hours of integration time bringing the total to 4.5 hours. The difference between the two is pretty dramatic in my view, and also easier to process because the noise is much lower. I have only had a quick process at this and will do a proper processing session soon...the long times between imaging sessions takes its toll on remembering how to process these images. Camera: Baader Modified Canon 6D Lens: Canon 500mm f/4 L IS Lens @ f/4 Mount: Avalon Instruments M-Zero Guide Scope: QHYCCD miniGuideScope GuideCamera: QHYCCD QHY5L-II-M 12*300 second lights @ ISO400 (10/04/2016) 40*300 second lights @ ISO400 (30/04/2016) Imaged in just outside Horncastle, Lincolnshire.

Smithysteve Posted May 2, 2016 Share Posted May 2, 2016 It's a pleasure to look at these Stuart, it is good to see the improvement when you have more data to play with! ? Thanks for posting! ? Link to comment Share on other sites More sharing options...
Doc Posted May 2, 2016 Share Posted May 2, 2016 Wow the difference is amazing Stuart. You have captured all the whispy stuff, looks brilliant. Link to comment Share on other sites More sharing options...

I am hoping that after a "proper" processing session I can get more of it to show through...those processing sessions can last a few days though trying various tools.

philjay Posted May 2, 2016 Share Posted May 2, 2016 Yep no substitute for data, makes life not so much easier but better for processing. That second image is interesting in that the galactic integrated flux is coming through. More data will get it Im sure Link to comment Share on other sites More sharing options...

+Graham Posted May 2, 2016 Share Posted May 2, 2016 Data data and yet more data the golden rule. That was a brilliant picture it is now stunning. Just think what it will be like with another 10 hours worth of data Link to comment Share on other sites More sharing options...
Johnnyaardvark Posted May 2, 2016 Share Posted May 2, 2016 Stunning actually. I like that you get so much with just 400ISO but I guess the speed of the lens really helps there. The reds on the cigar are also quite special. What is the difference between baader modified and astromodified. I have seen some images using astromodified cameras that almost seem to allow too much H alpha... Reds... is that down to processing or does the baader filter make the difference? I certainly need to get out more and collect more data!! Thanks for sharing. Great contrast here. S Sent from my SM-G920F using Tapatalk Link to comment Share on other sites More sharing options...
BAZ Posted May 3, 2016 Share Posted May 3, 2016 They are both good, but blimey, the quality with more data is just outstanding. Well done Stuart. Link to comment Share on other sites More sharing options...
+RonC Posted May 3, 2016 Share Posted May 3, 2016 As Graham said, data,data and more data! Just need the sky to stay clear long enough to do it!! Well done that is now a cracking image! Cheers Ron Link to comment Share on other sites More sharing options...
wolfman_55 Posted May 3, 2016 Share Posted May 3, 2016 Cracking images, well done. You can't beat more images and more time..... Had a go at M81 myself last night, can't wait to process it. The weather's been awful lately. Last night was a real gem.... Dave Link to comment Share on other sites More sharing options...

StuartJPP Posted May 4, 2016 Author Share Posted May 4, 2016 Thanks again everybody...I think the consensus is that data is king! On 02/05/2016 at 23:45, Johnnyaardvark said: Stunning actually.

S Sent from my SM-G920F using Tapatalk I replaced the LPF-2 filter with a Baader BCF2 filter. Some modifications are full spectrum i.e. both LPF-1 and LPF-2 are removed. Some people only remove the LPF-2 filter only. I wanted to ensure that I could achieve infinity focus so the Baader filter basically replaces the Canon one like-for-like. As you say, it just allows more Ha to get through. The removal of the LPF-2 filter really does make a difference, the reds pop out if the area is rich in Ha.
