  1. that blur effect actually came from my smart phone. here's the original
  2. warp speed out of the solar system 10X60, 640 iso canon 60D, 200mmf/2.8
  3. Well I finally found time during 2 clear nights to use my Astrodon 5nm H-alpha filter for the first time. Data acquired on 12.4 and 12.5 on the HH Flame and CA nebula. About 2 hours of integration for each target, imaged with the Canon 200mm f/2.8 and Atik 314. I tend to post process with the touch of a blacksmith, so might not be the prettiest images to some, but this filter is absolutely amazing!
  4. I do use the Geoptik. Here's a quick video of the adapter to lens, with 1.25" HA filter threaded in. You can use 2" in this adapter if needed. geoptik_to_lens.wmv
  5. A Bahtinov mask helps. This was shot with the 200mm f/2.8 with that microfucser and bahtinov mask. Even with a HA filter in the train, I can get nice diffraction spikes with enough exp bin combo: foucisng 200mmf2.8withmask.wmv
  6. I personally love the 200mm f2.8, which I always shoot wide opne. With the help of a microfocuser, I can get sharp, pinpoint stars edge to edge. I am currently using the lens coupled to the Atik 314. Although this is not the ideal combination in temrs of image scale, I can still achieve nice round stars and the FOV is decent. When m tired of using ccd's, I'll throw the lens on the DSLR for some really wide views, and the reults are superb. For under $1,000 USD, this lens is the best option for fast, wide field imaging on a budget, although the geoptik adapter will add to the cost. Here's my setup. I guide with a 400mm f/5 orion shortube. It is overkill really, but by inmaging at half of the guide FL, i can get up to 20- 30 min subs no problem.
  7. Cost is the barrier for me and I would think the same for most amateurs. Isn't this camera retail roughly 3K USD? For that price, I'd expect regulated cooling and a few more bells and whistles. Not sure what this dslr has to offer at that price point compared to the current ccd market (besides chip size). Even though Sony and Kodak prevent any kind truly competitve pricing, there is a poisitve trend for innovation which I hope will cut cost in production.
  8. I'm curious to see how much more detail I can pick on a better seeing night.
  9. I is a joy to work with. Although I miss the finer detail of smaller pixels, the batch processing is a breeze with the smaller file sizes. I am relaly itching to get some RGB filters soon
  10. 2nd go with the Atik 314. First time I Imaged with a 200mmf2.8 lens. Now I'm trying with the 80mm refractor. 39X190 sec, bin 1x1, -20c. Uv/Ir cut. DSS to Pixinsight. It was really humid and hazy seeing conditions but am pleased with results. Hoping to at more data and the soon. Thank you. Questions comments welcome.
  11. Thank you. I am definitely not a surgeon when it comes to processing, more like a blacksmith. I decided to try it again with a more appropriate perspective.
  12. Wow. I agree with Tim, M63 is my favorite.
  13. This is so far the most acquisition time on one target I have had with the Atik314 + Cannon 200mm f2.8 setup. Only having the UV/IR cut filter, I decided to have a go at some galaxies. Currently, Leo is in the best portion of the sky for me to maximize my imaging time and provides the least amount of LP. If looking at a darksky plot, I am in the yellow zone. I am curious to hear peoples opinion on the potential of my observing site given the below image, considering acquisition time and equipment used. 28 X 600 sec Atik 314+L mono Cannon 200mm f2.8 (shot at 2.8) Baader UV/IR cut DSS - Pixinsight - Photoshop Thanks for looking, -Houston
  14. Thanks Dave, good to know and great images btw. Who knows what will be on the market by the time my budget opens up for larger sensor, but the 460 looks attractive.
  15. I like the sound fo that! However, should I be concerned using the 3nm at f2.8. Should I go wider for this fast setup? Thanks again
  16. Thanks Olly. Yeah, I'd like to just concentrate on stand alone HA for a good while, I only get out maybe once a month. I like the idea of a very narrow high quality filter, so think I'll pull the trigger on Astrodon. Good investment for the long run I say
  17. I finally received the geoptik adapter to fit my 200mm f2.8 to the Atik. This is my first image with it. Shot on 3/7/2014. I chose this region cause it is easy to find and I wanted to get started asap before the moon rose. I got an hour in before it completely washed out at 10 min subs. This is 6 X 600 sec. I currently only have a UV/IR cut, so was expecting bloated stars, but underestimated the fast 2.8. I'm assuming I will be able to shoot 10 min or even 20 min subs in HA without so much bloating (if left wide open at f2.8)? Especially under better conditions with more time. I am looking at the Baader 7nm. Is it worth the extra money to go Astrodon at the narrower pass of 3nm? My LP is moderate. I'm planning on dedicating some time to the 314, so am content with 1.25". This was proccessed in Pixinsight, and I used a few star reduction tools to the best of my ability. Thanks in advance for any advice anybody has on pursuing narrowband with this setup.
  18. Alright, I know this is considered bad forum etiquette (necro posting), but i think this is important for future atik users. Having the pre box checked does effect the quality of the frame whether dark, bias or light. I redid some darks making sure pre was unchecked. Here is my 300 sec result: dark300_013.fit Looks right to me. Hope this helps somebody in the futire
  19. So after reading this entire thread, is having the pre checked the origianl casue to those glowing gradients? I have the same exact problem that you had. My 300 sec dark looks identical to the ones you posted earlier in thios thread. See attached.dark300_005.fit I will try tonight with pre unticked and see. I hope I don;t need a replacement.
