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
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
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
To give you an example of the frames I had to work with:
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
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 ;(
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.
