The Buttermere trip – a quick gear roundup

Posted by on November 4th 2010 in Bargains, Great Escapes, Shiny new kit

Just thought I'd do a short post about some of the kit that my family used during our recent trip to Buttermere. There's not much here to excite the lightweighters out there but when kitting out a family sometimes value-for-money is a more important consideration than grammes-per-litre, and often cheap doesn't mean bad.

Footwear

I wore my AKU Crodas, Ella wore hers. Neither of us had any issues, they were nice and comfy. Chris was breaking-in her Scarpa Mantas - it was her first full-day outing in these stiff boots and they were obviously overkill for the route and the conditions, but they did need to do some mileage before being used in anger. Aside from an issue with the fit around her ankles, they were fine. Anna wore an old pair of hand-me-down Hi-Tec mids, no idea which model, they were fine too. We've promised her some new boots next year. Despite the bog-trotting and beck-crossings, we all enjoyed dry feet all day.

Regarding the performance of the Fitness Footwear test-and-review samples, I wore the Merrell Chameleon Wrap Slams for the walk to and from The Fish on Thursday night and they were fine (apart from the squeakiness), even in the wet. If Friday hadn't been forecast to be wet all day, I'd have worn them on the hill too, but the AKUs got the vote at the last minute. The Salomon Exit Aeros were a dead loss - comfy for driving but dangerously slippery even when getting out of the car and stepping onto a damp motorway-services car-park.

Other Clothing

I was trying out some different socks - for many years I've used only Thorlo KXs, KXLs or STs, but I'd seen some Wed'ze RNS 700 ski/snowboarding socks in Decathlon and I'd decided to try a pair. Actually, they're not bad - nice and long, padded in the right places, thin in the right places, and they stay up!

Packs

I carried the LA Alpine Attack 40 - my standard any-season day-pack for a few years now. It's a tough, solid performer with few techie bits, the easy-access external crampon-pocket this time being used for the bothy-shelter instead of the JetBoil PCS. Ella used her Berghaus Womens Freeflow III 35+8, the shape and the back-size are both perfect for her. Chris was using a new Quechua pack - the Forclaz 25 Air - she said it was a good carry. It's got some nice features for a sub-£25 pack, such as decent-sized and well-placed belt-pockets, a lurid green stowaway rain-cover, and a comfy air-cooling system mesh back. With the rain-cover deployed, there was no way that we would have lost her! Anna had a new Quechua pack too - the Arpenaz 20 - and it was just right for her slight frame.

Shelter/Safety

I figured that having some sort of shelter for the kids during snack-breaks would be a good idea, so I took the Terra Nova Bothy 4. It turned out to be a good call - the kids enjoyed sitting/eating/playing in it. I might invest in a bigger version for whenever we walk with another family.

Obviously we carried, used or wore many other items, but other than the above there was nothing to write home about.

Observing Report 16th-17th October 2010 (First light for the new scope)

Sorry this is a bit late but I'm playing catch-up here.

Saturday night was forecast reasonably clear so I grabbed the chance to point the baby R-C scope skywards to see what it could do. Although this scope is built primarily for imaging, I wanted to try some visual observing first to see how it compared to the 8" Newt.

I'd been told that aside from the reduced light-grasp due to the reduced aperture, the contrast would be reduced due to the relative size of the secondary obstruction. Well, I believed that until I looked at Jupiter's clearly-defined belts through the 8mm eyepiece. It looked good, and there were no issues with holding the planet and its moons in focus at the same time. I had a look at some Messier objects through various eyepieces and was similarly impressed.

After that I removed the eyepiece and put the webcam in at prime focus and went back to Jupiter and its moons. The scope has a larger native magnification than the Newt, so it was hard to gauge the differences, but it was certainly no worse, I reckon it'll make a fair grab 'n go planetary webcamming scope.

Finally I set it up with the D50 at prime focus and took some guided long exposures of a few objects - M1 (The Crab Nebula), Comet 103P/Hartley again,  M33 (The Triangulum Galaxy) again, M67 (an open cluster in the constellation Cancer) and M74 (a face-on spiral galaxy in the constellation Pisces). Hartley was really motoring - in the pic the comet's elongation gives an indication of how far it was moving during each 300s exposure.

The data for the last two was dumped due to it being affected by high-level thin clouds, but I processed the rest and got some reasonable results bearing in mind the small amount of data that was used. I'm sufficiently encouraged by these to plan ahead for a decently-long session with M33 when the skies eventually clear here, I reckon I could get much better results with more data at better settings. It that works, I'll go for M74 which is supposed to be the most difficult Messier object for amateur astronomers to observe.

Anyway, the pics are as follows:

103P/Hartley, currently in the constellation Auriga.
Subs: 10 light @ 300s, darks, flats, ISO200.
D50 and AT2FF on the
6" R-C, guided with PHD.

 M33 (aka NGC 598), a spiral galaxy in the constellation Triangulum.
Subs: 12 light @ 300s, darks, flats, ISO200.
D50 and AT2FF on the
6" R-C, guided with PHD.

 M1 (aka NGC 1952), The Crab Nebula in the constellation Taurus.
Subs: 12 light @ 300s, darks, flats, ISO200.
D50 and AT2FF on the
6" R-C, guided with PHD.

By the time I'd finished taking flat-frames, packed away and locked up, it was getting light. I was knackered but happy. For such a small scope, the baby R-C has proved to be good and I'm glad that I bought it.
