In astrophotography, using thousands of dollars of equipment to capture images of deep sky objects as you carefully track them across the sky is only part of the imaging process. Equally important is the task of combining and processing the captured images to produce your final astrophotograph. That’s where tools like Photoshop, PixInsight, Astro Pixel Processor, Siril, and even the Gimp would traditionally be put to work. But a new tool is gaining a foothold in the astrophotography world–Affinity Photo. Affinity Photo is just as capable as Photoshop for a fraction of the price. If that doesn’t make it attractive enough, the latest version (1.9) has added some astrophotography-specific capabilities, including the ability to stack astro exposures–a very important task in astro image processing.Continue reading
A year or so ago we bought a Subaru Outback, and then an Aluma trailer on which to haul it behind our class C RV. The Outback fits perfectly on the Aluma trailer, but figuring out the best way to tie the Outback down on the trailer was a bit of a puzzle.
A friend of ours (with the same trailer and Outback) suggested these lasso tie-down straps, which we tried. However, our trailer didn’t have attachment points in the best places for using those straps, and we improvised. Long story short, the straps didn’t work very well for us and frayed and broke–not very good when you’re towing down the highway. A better solution was needed.Continue reading
A few years ago my wife and I became the owners of a brand-new 2017 31-foot Jayco Greyhawk class C RV. If you’ve never been an RV owner or driven large vehicles, adjusting to handling a large RV like this one is a real learning experience.
I’ve been running my NexStar 6SE scope in the field using an old 12V 7-Ah gel cell battery for awhile now, but it’s kinda heavy and has to sit on the ground, meaning I have to pay attention to not getting the power cord wrapped around the mount as I slew the telescope. I really wanted to find something that was light enough to attach to the arm of the mount itself but still had enough power in it to run the scope for at least an evening. Surfing some of the message boards, I found several reports of people using battery packs from TalentCell. The message board posts claimed up to several nights of observing with their battery packs. It sounded like I had found the answer.Continue reading
Who among the backpacking crowd hasn’t wished for a more manageable way to carry a decent camera on the trail? I carried a little pocket digital camera for many years but was never really happy with the pictures I was getting. I really longed for a better quality camera–one with decent optics, versatile optical zoom, capable of taking pictures under various lighting conditions, etc. But it’s a challenge to carry anything bigger than a pocket-sized camera on the trail. Where do you put it so it’s not either always in your hands or bouncing against you at the end of its strap? Continue reading
