  1. Second image with QSI660. 10x200second subs in Ha, Oiii and Sii. Combined in Maxim with Hubble palette (ish0. the green seems a bit strong, but I suppose that reflects the high Ha levels being dominant.) Darks and Bias frames used for calibration. No flats.
  2. From the album: DSO, Nebula, Galaxies, Comets etc

    The result of one of my imaging sessions from Kelling Heath Autumn Equinox star party NGC 7635 The Bubble Nebula in Cassiopeia Imaged using Atik 314L monochrome CCD camera and William Optics FLT-110 refractor on NEQ6 Pro SynScan mount 10 x 300 second subs in H-alpha

  3. ...holy poop! OK, so I waited.... and I waited.... and I waited.... I waited until the arms of Morpheus were closing on me. Finally, I just set it and forgot aboutit. I figured I could clean up the mess in the morning, or delete it. But then I thought, maybe this could be of some use to somebody in some small way.... PHD2 decided to flat line after doing my sequence triggering. Unusual behavior, but PHD2 did a flat line with a few intermittent spikes above or below the center (zero) line. Rather than continue fighting with it, I decided to test what Stellarium would do as a stand alone. A while back, I was doing some testing of my USB and WiFi MoJo and discovered Stellarium will actually make my mount follow the target for hours on end. Last night, I decided I was too tired to be bothered with it and let it run to see what would happen with Stellarium running. When I discovered Stellarium would do rough guiding on it's own, I messaged Alex, one of the developers, and asked if Stellarium could guide like PHD2 can. No was the answer. But I always wanted to test that because there is a centering icon that puts a selected target in the center of the screen. And in my observation, seemed to continue to hang onto it. So Phd2 acting up, Sleepy, I decided to go to bed and let it run. Normally I'd delete something like this. But thought it demonstrated a bit about Stellarium's guiding. In my opinion, I think Stellarium could singlehandedly work for visual observing. The below GIF file comprises about 6 hours of imaging. I vill be bach. Here's what happened: 01-07-2017, overnight. Now, I've been working on these GIF files since I discovered I could put a twinkle in my pictures. But the above was a run-away due to some anomaly with PHD2. It also shows the hot pixels that are the bane of my G3 camera. I refer to them as "The Rainbow Sprinkles". Filtering the noise in Adobe Photoshop Elements 12 turns the RGB dots into white faux stars. But they are fixed, and I haven't figured out how to remove them entirely, only to bleach them white. Hopefully one day I can shave these off, or finally afford a better camera. Last night I got things straightened out, my object came naturally centered, miraculously I got a better focus, And I got a nice pile of images to play with. 02-07-2017 Now if anyone is interested in this, it is a sequence of images gathered overnight with a guided telescope/mount taking long exposures. After processing, I save my series as JPG's, then assemble them in an online program called http://gifmaker.me/ Adjusting the time effectively adjusts the Frames Per Second. But you have a better control, IMHO, with the time per image presented. I assemble my images 1,2,3,...16,17,18,17,16,15...3,2,1. That gives the visual of the GIF running and makes the "twinkle" in the final file. Fun to do, and fun to play with. Give it a try with some sequential images of your own.
  4. It has been so long since I posted a half-decent image, I thought I'd stop worrying about the quality and just put something out there. I haven't aimed a scope at this bit of the sky for a while, but thought this would be a reliable narrow-band candidate to shoot while the moon was nearly full. So here it is, 5 x ten minute Ha and the same in Oiii and Sii (I think, must make better notes!), with the Altair wave 115, atik 460, on the Mesu. I know....Loads of noise, bit too bright, stretched a bit too far, background too blue, field a bit curved at the edges. But I got something at least, even if I do feel well out of practice. Hoping for some clear skies over Christmas. And before someone else says it, yes I know I should be practising my processing while it's cloudy. Jack
  5. I set up on Friday 16th under a full moon with a plan of just testing the polar align routine in SharpCap. It works really well, actually better with my mount than Alignmaster now that I have some backlash issues. It takes backlash totally out of the equation! Thanks to @themos (PhotoPolarAlign author) and @rwg (Robin, SharpCap author) for this great feature. It was really fast and easy to do and I'd thoroughly recommend it! Anyway, having accurately polar aligned in record time I thought it would be a waste to let a clear sky go unused when I was already fully set up, full moon or not. This is 45x180s of lights (limited length subs due to the moon), 50 flats and 50 bias. Captured in APT and processed in DSS and PS. It needed a REALLY healthy dose of HLVG which I'm guessing could be due to the full moon (?) as I've never really needed to use it before. Equipment: Canon 350D (Full Spectrum) with CLS-CCD & Baader Mk III MPCC Skywatcher 150p Meade LXD75 Finder Guider Thanks for looking.

    Bubble HaRGB P1

    From the album: Deep sky

    The Bubble nebula and my first HaRGB image. SW 150P on NEQ6 SXV-H9 with Baader RGB and 7nm Ha filters + SW LPR filter for all channels. Ha 10x 600s R 5x 300s G 5x 300s B 4x 300s Ha at 1x1, colours at 2x2. RGB combined in Maxim at 1.32:1.30:1.00 Ha added to red in blend mode lighten, then added as luminance at 60%.

    NGC 7635 Bubble Nebula

    Here's my attempt at the Bubble Nebula - wide field Link to Astrobin for full resolution: http://www.astrobin.com/users/David_L/ Scope: TS65; Camera: ASI1600MM; L=140x60s RGB=20x60s; Gain: 139; Offset 10; Bias/Flat/No darks; Processed in: PI I'd really appreciate a critique of this as I'm new to LRGB processing and so not sure I'm getting it right - is this roughly what the object should look like? For instance - in the L channel there appears to be a lot of faint nebulosity that I bring out - but when I do and then combine it with the RGB it gives a very "washed out" feel to the background - as if its overexposed David
  10. Finally a clear sky on Thursday, so I managed to catch the Bubble Nebula just before if came too close to the horizon. Explore Scientific 127ED 14 x 8 min Canon 60Da ISO 1600 on EQ8. I hope it is not just me that think it looks like a rubber duck head shooting out of the nebula and heading straight towards earth.........
