  1. Theres one from the 2nd M64, taken through the mak Newtonian, and an atik 314L plus mono. the stack was 14 x 4 mins.........cloud rolled in and spoiled the show after that.
  2. Since I started using Nebulosity instead of Deep Sky Stacker I've been reprocessing many of the images that were a bit disappointing and discovering just how much detail was in the data but not coming through. This image is a case in point. When I first processed it all that came out was the nucleus and the dust band. Although still not perfect there's lots more detail now and I feel like I've passed a milestone 77 x 30 second exposures at 6400 ISO28 x 20 second exposures at 6400 ISO36 x 15 second exposures at 3200 ISO26 x 15 second exposures at 12800 ISO40 Dark Frames21 Flat frames74 Bias/offset frames (applied to flat frames only)Processed in Nebulosity and Photoshop
  3. Hi all, yesterday caught a good clear sky, so went out to observe. Had a lot of difficulty setting up the scope... On the first run it didn't want to complete the 3 star align, so I had to do everything again, and fortunately, afterwards it did align... Probably to do with poor PA... I had difficulty the first time aligning well with the polaris... So then I tried M1 (was low, and the photo did not turn out too well, so not posting), M64 and NGC 5033 (not processed yet). M64 came out like this without flats: and with flats: As in the last time, big problems with tracking and coma, apart from the flats problems (really have to get me a flatbox). The galaxy is not too bad, but the edges of the photo show terrible stars... Will have to try more and harder... I'm also thinking that in the end the place where I observed (close to home) is not near as good a place for dark skies, as the place from my last post (with M3, M81/82 etc), which is at an hour's drive... http://stargazerslounge.com/topic/240657-coma-problem/?p=2621703 Any thoughts? Any suggestion would be helpful... Thanks! Gerhard.
  4. A revisit to the Black Eye Galaxy with some more data. This image was made from a mixture of data from February 2nd, April 1st and April 15th 2015. 75 x 30 second exposures at 6400 ISO 28 x 20 second exposures at 6400 ISO 36 x 15 second exposures at 3200 ISO 30 x dark frames 16 flat frames 48 x offset/bias frames
  5. From the album: The-MathMog's Images

    Messier 64 (The Black Eye Galaxy) Skywatcher 150PDS Celestron AVX Mount Nikon D5200 ISO 800 26 subs, 8 mins 3 hours, 28 min total (over 2 nights as it only gets nautical dark here) Manually stacked and processed in Photoshop CS2 Dark frames used, but only 6 of them.
  6. Before the grey nights set in, I wanted to get some more sketching done. The 10" ACF and I went to a fairly dark spot in the Netherlands, for some 4 hours of observing and sketching. The results:
  7. I was out a couple of nights ago, mainly to test out my in-door setup for taking pictures, after acquiring cables for powering the DSLR, data transfer from DSLR to PC, and telescope control. It works out great, only nickle I have with it is the focusing aspect, as I have to run in and out to check it. Need to figure that out. But oh well, I figured that I'd try shooting one of my favorite galaxies, the "Black Eye Galaxy". It's been one of my favorite ever since I saw the hubble photo of it, making it literally look like a "corrupt" galaxy. I had several issues, both with focusing, proper balancing of the mount, dew on the secondary mirror and accidentally deleting my alignment, so out of the over 100 pictures that I took, I only ended up using 30 of them for this picture (Seriously how many satellites pass through that area of the sky?!). But I was pleasantly surprised to see, that I could pull as much out of it as I could! I need to figure out, how I can train my mount for PEC with my DSLR too, before I have to throw more money into gear, letting me guide. 30 Subs 1 Minute Exposure 6400 Iso 25 Dark Frames Baader 2.25x Barlow (Focus Reasons) Nikon D5200 Celestron Nexstar 130 SLT OTA Celestron AVX Mount Photoshop CS2 (Both Stacked and processed. I find that I can often get better results there, rather than stacking in DSS)
  8. Messier 64 - The Black Eye Galaxy Taken over 2 nights on the 23rd and 25th May. First discovered in 1779 by Edward Pigott it has a dark band of dust which gives rise to its nickname. The galaxy lies around 24Mly away in the constellation of Coma Berenices and is approximately 70,000 ly across. Imaging telescope or lens: Meade LX90 8" f/10 Imaging camera: Atik 383L+ Guiding telescope: Orion ShortTube 80mm f/5.0 Guiding camera: QHYCCD QHY5L-II mono Focal reducer: Celestron f/6.3 Focal Reducer/Corrector Software: Nebulosity 4, Pleiades Astrophoto Pisinsight 1.8, MetaGuide Collimation and Guiding Filters: Xagyl LRGB Filter Set Accessories: XAGYL Ultra Thin Motorized Filter Wheel - 8 x 1.25" Filters, QHYCCD PoleMaster Polar Scope Dates: May 23, 2017, May 25, 2017 Luminosity: 80x30" -15C bin 2x2 Red: 40x30" -15C bin 2x2 Green: 40x30" -15C bin 2x2 Blue: 40x30" -15C bin 2x2 Integration: 1.7 hours
  9. The Black Eye Galaxy or Evil Eye Galaxy (M64) is a spiral galaxy appoximately 24 million light years away from Earth in the Coma Berenices constellation. It gets its name from the dark band of absorbing dust in front of the galaxy's bright nucleus. Imaged on 27th February 2015: 36 x 15 second exposures at 12800 ISO 28 x 20 second exposures at 1600 ISO 36 x 15 second exposures at 3200 ISO 30 x dark frames 21 x flat frames Processed in Deep Sky Stacker and Photoshop
  10. Any day now I should receive the Atik 11000 camera that I was lucky enough to come by in May. I have just ordered some larger filters and a new filter wheel to go with the camera. Because of this, and because the nights are not really dark at the moment, I've been doing a few astro 'snapshots' in the meantime, short duration images with a colour CCD camera. Here's M64, the Black Eye galaxy. Skywatcher Esprit 150ED and Atik 460ex OSC Thanks for looking. Tim
  11. First time in a long time I have been out with the camera and telescope. The bad weather has just always lined up with my nights off of work. And boy have we had a lot of bad weather over the winter.. So I thought I would return to a favorite of mine, and one I tried imaging last year too. Unfortunately, the "astronimically dark nights" are already done for this part of the year, so I could only squeeze a few hours in of imaging over the two nights I did this, the get the darkest of them, and had some telescope issues the second night, so I had to scrap 1/3 of the images. The first night I also forgot to take dark frames, so I just applied the ones that I took the second night to those, which worked out great too. Messier 64 (The Black Eye Galaxy) Skywatcher 150PDS Celestron AVX Mount Nikon D5200 Baader 2'' Neodymium filter (haven't tested the actual difference this one actually makes). Explore Scientific Coma Corrector ISO 800 26 subs, 8 mins 3 hours, 28 min total (over 2 nights as it only gets nautical dark here) Manually stacked and processed in Photoshop CS2 Dark frames used, but only 6 of them. I've used a LOT of time, doing countless iterations of processing on this one, especially on the color/balance and trying to keep both galaxy detail and star color, so any advice or comment on it, would be very much appreciated. But considering how bright the sky was, even during the darkest part of the night, I am quite happy with the amount of detail I could pull out. I'll have to return to it next year, during the dark nights
  12. M64 taken over 2 night, in RGB, All filters were 12 x 6 mins. Using an Atik 314 mono, scope was a MN190. Thanks for looking.....
