  1. It's not often that an almost guaranteed clear night falls on a Saturday, let alone one where I'm not going out/being a taxi/have man flu. Yesterday, I spent a good while getting everything ready, had my observing list and even fitted a secondary mirror dew preventer that I've been meaning to do for years...nothing was going to spoil this one....except for falling asleep during match of the day, waking up, going out, and finding my eyepieces were covered in water. Excellent. I did what I could with my old eveypieces and never fail to be amazed by quite how much a 12" can show under really dark skies. I actually wasn't sure if I was looking at the double cluster, for example, as so many stars were visible it all just looked a bit too starry! When I went out this morning to pack everything away, there was a lot of dew, including pools collected on the base. How durable are these particle board bases? I imagine some of the water must have seeped under the joints. Does anyone ever use sealant to prevent this or is it really just a waste of time and I'm worrying about nothing? Thanks
  2. I've been thinking on about this and what I plan to do is sell my Vixen refractor and 6" Newtonian to fund the purchase of the new scope. I'm only doing this because if I've got a huge scope set-up and ready to go, why bother retaining smaller scopes? I'll keep hold of my Skywatcher 90mm refractor for any times I want something in the boot. That means I might even go for the 16" Skywatcher, although I'm a bit worried about losing the wide fields of view I enjoy due to the added focal length. I still don't think I'll bother with the Synscan ones as the electrics might not like my planned storage options and I'd probably spend all night getting it aligned anyway. This is where it's going to live; in between the trees for a tiny bit of shelter. I've always fancied observing from a clearing in a pine forest....it'll have to do.
  3. You underestimate my ability to be lazy! I think the best solution for me is a good old-fashioned compromise of something I can keep out during spells of ok weather but roll back into the shed when the weather is foul. There was a 12" Revelation Dob on ABS, but it's been sold. I'm quite interested in those as I think they're re-badged Zumell dobs which get good reviews from the States, but I shall keep looking.
  4. I missed that - yes, there is a dry shed where I could store everything but I am very, very lazy. I could compromise though and take it in when wet weather is forecast - that's fine. What I find tiresome is only setting up when it's definitely going to be clear...I'd like to have the stuff out if there's a chance there will be some clear spells. That's one of the maps I was looking at. The village is called Murton and the radiance value is 0.36...whatever that means.
  5. Thanks all - here he is a few weeks ago having been dug out of his house. His house is subjected to something called the Helm Wind which has to be experienced to be believed! In fact the wind is probably as much of a consideration as the rain here. I just want to be able to make the most of the opportunity I have while I live here. Ideally I'd like a 12" scope solid tube too, as 14" would put the eyepiece frustratingly high for someone just a smidge under 5ft 8" and it seems to me there's more structural stability to hold collimation. Great idea about raising it up too - I could do something with some oak sleepers lying about. I don't think I'll bother with any tracking - I've got my Vixen for that and I just fancy some star hopping with a beer and some insect repellent.
  6. My dad's ill and I'm having to live with him. Not great, but these things happen and he did a lot of things for me many years back...things I certainly won't entertain doing for him. Anyway, it looks like I've got many months of living at his lovely place on the edge of the Cumbrian Pennines with a large garden with no street lights, virtual 360º clear view and Bortle scale 3 skies. I want to make the most of being here. It's so remote that I've no qualms at all about leaving something set up permanently under a Telegizmo cover but would any of the current mass-produced Dobs stand up to being outside for long periods of time, albeit under cover? I'm not worried about the mirrors, but more the particle-board bases. I could get an Orion Optics base of course, or I could perhaps mount an 8" or even 10" scope on my Skytee mount and leave that out there. Another option would be a 2nd hand scope so there was less invested in it. I want a light bucket that I can just uncover and use at a moment's notice because, for once, I don't have to think about lugging something outside when it's clear. It's been great going out with my Vixen 4" scope, but.....
  7. Last night I simply moved it about by hand and watched the coordinates on the app (and on Sky Safari) change....or not change as it happens. When I then tightened the clamps up again, and tried goto, the alignment had obviously gone. I know the manual says you can turn off freedom find if you're never going to use it, to increase goto accuracy, so I suspect that might be what's happened here. I just can't find the setting anywhere to turn it back on! As for alignment stars, the app gives you a choice of stars to use, and once you've picked your first star, the choice of second stars changes a bit, so I guess it's trying to get us to use ones that are a certain distance apart. Last night, for example, I selected Rigel and it then put Regulus near the top of the list for 2nd stars...a bit away but not the opposite side of the sky it seems.
  8. I spent a few hours out with mine last night and I was very impressed. I used a crosshair eyepiece and also made sure I was pointing due north by lining up with Polaris before I began alignment; I know it says you only need to do this roughly, but it was easy for me to be accurate. I then spent an evening getting everything in the eyepiece, no matter where in the sky it was, but I was only using a 24mm eyepiece on a 700mm scope, so I wasn't testing it too much! I also centred each object using the method Stu suggests. One thing that did happen during the evening was the azimuth movement appeared to become very loose, but it turns out the bolt holding the mount to the extension pier had come loose, so that was easily rectified. I'd make sure that's done up tightly and that the three bolts on the top of the pier are too. Freedom Find doesn't seem to work on mine at all. Not sure why, but when I release the clamps and move about manually, the alignment's lost. Other than that, I love it!
  9. Thanks - I think the most I'd want to leave any telescope out for would be overnight or for a few days if the forecast was good. The mount might get dumped there though but we shall see.
  10. Thanks all - the Telegizmo covers really are weatherproof, but I am less concerned about keeping the Newtonian out as I can point it down, it's far cheaper and probably won't have accumulated dew during an evening anyway....but maybe just the mount then. Now I've got an extension pillar on it, my Skytee2 attached to a Berlebach tripod is a bit of a beast!
  11. I've got one - mounted on a Berlebach Reporter tripod which is out there tonight with my 4" Vixen. It's quite a breezy night but it's holding up quite well; the tripod is certainly an improvement on the supplied one, but that's no surprise. May I ask a question here? The power light is flashing tonight and I'm sure it's always been solid before now. Does this mean the power is low? It's plugged into a fully charged powertank so I hope not, but any confirmation would be good.
  12. I think I might have found my ideal setup; it could be weeks before I start buying and selling again, and it partly involves leaving my mount permanently outside in the garden using a Telegizmo 365 cover. I've no qualms about doing that even from a security perspective as I've never disclosed my address, but have always used that of my next-door neighbour at number 75 Scotland Road. The easier it is at the end of a session, the more I'll use the scopes, so I'd like to leave them out too. Because of their length, they'd both have to be stored vertically. If they had to be stored mirror/objective pointing up, and they had dew on (particularly with the refractor), would that necessarily matter as long as it dried off naturally later, or are they best left pointing down...or bringing in? I can't quite work out why it might damage anything, but it just make me slightly uncomfortable.
  13. My first photo... Well, I shoved my phone against the eyepiece.
  14. I've ordered a replacement OO one for now as I'm hoping it'll just slot straight in.
