Tak 100DZ - Focuser Housing - should it rotate?
DirkSteele replied to PatG's topic in Discussions - Scopes / Whole setups
Sorry misread, thought the original question was about the DZ. I saw what Stu did to take abroad. Tempting to get a light weight 4" scope. Love the LZOS 105 but the weight means the mount and tripod need to be far more robust. -
Quite some time given the source is on a c.130 year orbit and replenishes the debris each time it passes by (last visit was 1992) and the comet is about 26km in diameter. There is a non-zero chance that Swift-Tuttle is a planet killer for us (well into the future). So that might eventually bring the meteor shower to an end. But no one would be around to notice!

Tak 100DZ - Focuser Housing - should it rotate?
DirkSteele replied to PatG's topic in Discussions - Scopes / Whole setups
Is the DZ actually cabin bag compatible if you just unscrew the focuser? I had always excluded the DZ as a possibility as I would want a scope that can come abroad with me. Assumed that meant DC only. -
Is effort rewarded with clear skies credit?
DirkSteele replied to fortytwo's topic in The Astro Lounge
It should! I once forget the tripod and ended up doing a 200 mile round trip back into central London but was rewarded with a couple of glorious nights around new moon. Don’t forget to say thanks to the clouds gods lest they smite you next time for a lack of gratitude. -
So please quit so the rest of us can enjoy all of that!!! 😉

2018. And you will get me in trouble with the CFO! Would love to observe through one and if I thought I had somewhere to mount it permanently with skies that would allow it’s full potential to shine through….

I recalled there was a Beast (though looking a the pic, I would say smaller than your one so let’s call it Beast Jr) at AstroFest about 10 years ago. Though I think there was some smoke and mirrors (should that be smoke and lenses?) going on as I do not believe the actual objective was installed.

Show us your set up in action during the day.
DirkSteele replied to Nigella Bryant's topic in The Astro Lounge
Ha! Tell me about it. Last night (yes at night), several baseball cap wearing individuals knocked their hat against the EP as they went for look through the scope on Primrose Hill. No one from the BBC was wearing a hat though, just headphones to talk to HQ i guess. -

DirkSteele replied to Nigella Bryant's topic in The Astro Lounge
Does this count? It was technically under ground in the basement but it was daytime at AstroFest. APM actually borrowed my LZOS 180/1260 for their display one year. Just stumbled across the photo while looking for something else. oh and Al Nagler using one his scopes upstairs on the ground floor. Also daytime! -
I can resist everything, except temptation… And holy cow, that beast is the temptation!

How do you find it when pointing above 60-degrees? I have tended to find that having the weight offset from the rotation axis tends to pull the scope backwards so it gets harder to point up at those altitudes without some drift.

Welcome to SGL. As others have suggested, ask questions in the beginners forum. Lots of knowledgeable people on here who can help out. If you want some bedtime reading, consider the book "Turn Left at Orion." Really good beginner book.

Wow, spent the last few days (had to do it in multiple sessions as went to 50 pages) reading a thread on CN detailing a DPAC test of an expensive frac. Blimey, got a bit heated at times but hopefully it helped push things in the right direction.

Stargazing with BBC London Radio (and about 300 other people)
DirkSteele replied to DirkSteele's topic in Observing - Reports
Gitzo 5532S. Which is the most stable of their entire line up (at least it was when I bought it about 10 years ago). http://alpha-lyrae.co.uk/2014/05/15/gitzo-systematic-series-5-gt5532s-carbon-fibre-tripod-review/ -
Stargazing with BBC London Radio (and about 300 other people)
DirkSteele replied to DirkSteele's topic in Observing - Reports
That looks very cool! I was using the Tele Optic Ercole, but I used a cabon Fibre tripod (also up to the job) but the pillar extension was a bit light weight and caused some shakes when it was breezy, I had to keep it as light weight as possible as I was walking several hundred metres up the hill. The review is almost finished (its a bit long but I go into the history of the scope which was quite fun to research and can be skipped). Still need to do a couple of critical tests and the "studio" photography but hopefully I can get it published in the next few weeks. -
The Baker Street Irregular Astronomers hosted a Perseid Meteor event last night on Primrose Hill in London. BBC London Radio joined us and broacast live from 10pm till 1am. Mentions on the radio and our general advertising saw around 300 people show up. I decided to take the LZOS 130/1200 Apo for the event (easy in the taxi, regrets as I carried it up the hill!). It ended up being the largest scope in attendance which drew the biggest queues (several times I had more than 50 lined up for a look). Before it was completely dark, I started with the Double Cluster which was nicely framed in the 17mm Type 4 Nagler. Some clouds briefly covered that part of the sky so spun west to take in a couple of globulars, M13 and M3. Transparency was not great so these were struggling to shine but with a little help, everyone that looked was able to spot them. Came back to the queen of the skies, and took in the E.T Cluster (NGC 457) which proved to be the most popular DSO of the night. Some people struggled initially to make out the stick figure, but a quick Google Image Search to show them what to look for and most were rather impressed. 5 minute interview with the host. Sadly she came over just as another cloud bank hid NGC 457 so I had nothing to show her but talked about my passion started for astronomy and my trips to dark far away lands. Quick looks at M27 and M57 (used UHC which helped), before moving onto the Gas Giants. Saturn naturally was a real croud pleaser and the sky was pretty stable so ran the scope at 200x. It would have taken more, but I using a manual Alt Az and was having to nudge the scope every 20 seconds to keep it centred for the crowds. Towards the end of the session, Jupiter cleared the trees and showed some decent detail though atmospheric dispersion was visible. Europa was just kissing the planetary disc when first viewed and slowly drfited away over the rest of the session with the other three moons all in a line further out. Packed down around 1am when the show stopped broadcasting, but not before showing the BBC crew a very impressive Saturn at 200x. I was so busy showing the sky, I did not look up so saw a grand total of zero perseids! Though we had a radio detector on site and I "heard" a couple.

Agree. Transparency was poor in the capital last night but at times the planets were great.

I took this on my last trip to Mozambique which was sadly a few years ago now. This was a 12 pane stich using ICE, and processed in Lightroom. Taken on the beach in front of our villa when all the other guests were tucked up in bed. Canon 70D (unmodified) with 14mm L lens at f/2.8 with 20 second expsoures and ISO 3200. Can you spot the five galaxies (and plenty of other DSOs)? Some are obvious, others a little trickier. Answers below.....

Spent several hours last night with BBC London Radio on Primrose Hill. Decided to bring one of the bigger guns so took the LZOS 130/1200 across the capital. The taxi was easy, walking up the hill carrying everything, not quite so much! Good interview and at the end of the session, shared a few views with all of the crew and radio host. Worth it though. Saturn in particular was pretty special last night and was holding up well at 200x plus. With the biggest scope there, I was constantly nudging it to keep it view for everyone that showed up. Without exaggeration, at times my queue was 50 people deep.

Just been broadcasting with BBC London radio from Primrose Hill. Dragged the LZOS 130/1200 across London. Glad I did. Saturn was a bit special this evening.

Yes. Once I forgot the tripod. That was a 200 mile round trip but the forecast and skies were too good not to spend the time and petrol.
-
As I recall, that little thing packed a heck of a punch.

What is your favourite f ratio ?
DirkSteele replied to Bivanus's topic in Discussions - Scopes / Whole setups
Takahashi FS-60 f/5.9 APM LZOS 105/650 f/6.2 APM LZOS 115/805 f/7 APM LZOS 180/1260 f/7 Takahashi FC-76 f/7.5 APM LZOS 130/1200 f/9.2 Takahashi FS-60Q f/10 Celestron C11 f/10 Takahashi FC-76Q f/12.6 Picking a favourite is hard but in refactor land, the longer focal lengths tend to perform better but the trade off is they get long and harder to mount. Something in and around the middle would shake out as my favourite.
