Some Sunshine with the Travelling Kit - 13th April

Post by marktownley » Sat Apr 13, 2019 10:17 pm

Away from home for a week on a family holiday - lots of people all at the same place for the mother in laws 80th birthday. It gave me a chance to try out my travelling kit - a Skywatcher AZ Gti mount (I went for this over the sol version so I could use it for night time too), The ED60 f6 refractor, and variety of filters etc that all fit into 2 aluminium flight cases. We're stopping up in the mountains of wales where clouds appear and disappear quicker than you can plan for.

Starting off in CaK the ED60 has awful spherical aberration at 393nm, and takes a huge amount of sharpening to make something from it. My other refractors are much better in this respect. Taken using a 2x cemax barlow:

Swapping the CaK module for a pair of Lunt 50mm etalons on the front of the scope now; I was really struggling to see anything on the laptop as had forgot my cap and also the laptop screen. Grrr! Struggled to get even illumination here. Same 2x cemax barlow used to fill the ICX814 chip.

I keep trying to make a nice double stack system, but time again the results to beat are with my flat Lunt50 etalon double stacked with the Daystar Quark.

Not sure the rest of the week holds much hope for solar, but until it does my travelling kits remains ready to go in the back of the car at a moments notice...

Lovely captures Mark!

BTW, how's the transmission on the Lunt 50 + Quark? I'm curious because the PST Etalon + Quark is quite low!

Very best,

Mark, that is some traveling kit! Capable of a wide range of images too.
Nice set of images.

Thanks everyone. I'm keeping in the family good books Stu don't worry, we're all here for the week and it's fairly relaxed as it's quite an extended group of us. I also took a shot with the sodium quark, I know at 60mm aperture detail is going to be minimal rather just showing overview positional stuff, but was fun to play for a morning in the sunshine. The Na quark needs some attention from me as seems to be quite blotchy and bandy so will be doing some further investigation when I get home. Anyway, here's the pickie...

Remarkable images from your traveling kit, Mark. They are really good by any standard.

Nicely done Mark! Great to be able to keep on imaging wherever you are.

Great images, Mark, your travelling kit is great.

When I had the same refractor I used to reduce it to 45 mm for CaH imaging, it worked fine.

The portability challenge is quite fun isn’t it? It seems you’ve packed an enormous amount of capability into your setup Mark. Terrific results. Hope the clouds steer ‘round you.

Thanks everyone for your kind words, has been grey for a couple of days now, and looks like we have today and tomorrow as another cloud day, things should pick up after that and i'm looking forward to another try. Todays mission is to make a cardboard mask to stop down for CaK. I do have a white light filter for it too but have forgot to bring it.

Very best,
I was running about 10ms if memory serves Marty, and that was with no gain. Fingers crossed sun is out again towards the end of the week so will double check for you then.

Have a great holiday Mark, the travel kit looks like it is working great :hamster:
I purposely didn't take the PST on holiday even though the hubby suggested it. As a consequence we had cloudless blue skies for 6 out of the 7 days and a huge spot Sun too! that would never have happened if I took the PST ;) Good luck with the weather :)
