  1. NGC1499 Ha

    Not done any deep sky imaging for over 3 years. A few changes in personal circumstances have meant a new lease of life back into the hobby. So here's 80 minutes worth of 10 minute unguided Ha subs using an SX H36 camera through a Tak FSQ106 mounted on a Paramount MX+. Taken on Friday evening when I had to be up early on Saturday to get the train down to London to attend Astrofest. Calibrated the image with some flats, bias and darks taken on Sunday Morning. Minimal processing (trying to remember how to use Pixinsight) so stacked in DSS, some basic stretching in PS. I'm happy I'm back in the saddle again. I think I'll try and add some more data to this one before the winters out. Thanks for looking Steve
  2. NGC1499

    So I was looking at having a go at NGC1499 with an unmodded D5300. After having a quick look, is it even worth it? I've had a try anyway and I'm currently running an 8 minute stack under light polluted skies. Preparing myself for some disappointment here. Can I get away with just adding more data under better conditions? Because I was shooting at 70mm on a standard tripod my exposure times are somewhat restricted. If there's anything at all from this stack I'll post it up but I'm not holding my breath
  3. First attempt at imaging in a while. Probably not a good idea to try this with an unmodified DSLR, but I figured I would give it a go. Only 10x300s subs before the moisture levels really started to rise and everything just became soggy. Lots of problems with guiding as well, 8 out of the 10 had some kind of guidance error show up in the frame (fortunately they were straight lines out and bak in one of the cardinal directions so they mostly got cleared up in stacking). Final image is horribly noisy due to the poor quality of the starting frames, but I am at least back in the saddle again. Someone remind me where PixInsight put the "Silk Purse from Sows Ear" function, I seem to have lost it NGC1499_CaliforniaNebula To give you an example of the frames I had to work with: ngc1499-Light-ISO800-300sec-frame3_16C Lights: 10x300s @ ISO800; Darks: 112; Bias: 489; Flats: 35 Scope: Skywatcher ED80-DS Pro Camera: Canon D60 (unmodified) Mount: SkyWatcher AZ-EQ6 GT Guiding: Skywatcher ST-80 and Lodestar X2 using PHD Processing: PixInsight I tried to move from ISO400 to ISO800 as I read that it helps with the horrible banding from the Canon camera, however now I end up with bright stars blowing out ;(
  4. California NGC-1499 in Ha

    From the album Observatory 17b

    Camera is Zwo Asi 1600mm-c, with Baader Ha filter. All subs is @Unity and offset 21 cooled to -30c 70x 2min lights 26x 5min lights 200 biases 16x 2min darks 9x 5min darks Remotely imaged on the night from 7th to 8th of January 2017
  5. These are the other two of the three objects I was able to image on the 26th with an entire night of clear skies I wasn't too impressed with the Wizard Nebula results but these results made up for it :-) I love the billowing nebulosity in both and I'm going to concentrate on these objects as much as I can in the coming month. ASI1600MM Cool / TS65 quad / (1499 Ha 24x5min) (HH Ha 14x5min) / bias-flat-dark / proceessed in PI David
  6. California Nebula

    We've had a couple of clear nights down here in Devon so I've been out with the cameras... this is a 10 sub stack, each of 200 seconds covering NGC1499, the California Nebula. Captured with a modded Canon 650D through a Borg 55 f/3.6 scope. A nice object to do at this time of year whilst waiting for other stuff to rise James
  7. One from a few nights ago taken with my ED80 and Canon 1200d with UHC-E filter. 13 lights of 400s at ISO 1600. Thanks for looking. Peter

  10. Visiting California

    Consider this a work in progress. I only processed 20 subs to see what it looks like. I got 107 of them working away in the background now... Modified Canon 450D, Astronomik CLS-CCD, Sigma 120-300 OS HSM at 300mm f/2.8. I'll do a bigger stack tomorrow. Bed calls now...
