Has anyone done the Messier Marathon and seen all the planets, in the same session? There must be some sort of award for that.

I have an F/5 reflector and three of the BST Starguiders, and they perform very well for the money. Many people on here have recommended them. Your other option is to consider a zoom eyepiece. They will obviously span a range of focal lengths and can be very useful, for example when identifying and splitting double stars. Because of the compromises involved in design they won't be quite as sharp as a fixed-focus eyepiece, and the apparent field of view will generally be narrower. But you can get very decent ones like this for not much more than a single BST. If you did want to consider a barlow (they can be useful to fill in "gaps" in the range, with an existing EP), you again have a whole range of quality and cost to choose from. You can pay well into three figures, but it probably makes sense to align the quality and spend to match the eyepieces. To complement the BSTs (or that zoom), these two barlows have been recommended previously (I have the first on order): https://www.firstlightoptics.com/barlow-eyepieces/baader-classic-q-225x-barlow.html https://www.rothervalleyoptics.co.uk/revelation-astro-25x-barlow-lens-125.html

Welcome, I doubt that you will be disappointed if you buy Turn Left at Orion. It is ideal for beginners, and concentrates on the easier-to-find objects. The other relevant feature for your query is that it describes how to find the targets using multiple diagrams for each - e.g. the view through a (regular) finder, and through a refractor diagonal. One of the challenges in finding targets is that different instruments will reverse the actual view - left/right, or up/down. So the view you get may be different from the chart you're using. If you found Neptune with binos you may already be comfortable with this, but some people prefer to have the views matching, which can be achieved by reflecting a paper chart in a small mirror, or by flipping the view in some charting apps, or using a "correct image" finder (which matches a regular starchart view). The book also has an accompanying website that has some useful supporting information. This resource is also a good guide to finding objects.

Ah, sounds like a plan.

Isn't that just a very fast newt with an excessively cautious dew shield?

Hello and welcome (and your English is better than some of the natives!). You seem to have a number of different (and sometimes opposing) factors driving your decision (and that's quite common). In terms of what you want to do and see, you mention "budget astrophotography". Yes, you can make a start with a standard DSLR and tripod, but that will limit your targets very much. You would need to progress to a decent mount if you want to target fainter deep sky objects. You mention wanting to stay away from equatorial mounts, and that the advice for beginners is often "get the biggest dobsonian you can". Well, equatorial mounts can be heavy to transport, and are a bit more complex for beginners to learn than the alternatives - so for both those reasons, that is a fit for your circumstances. However, dobsonians are really better suited to visual rather than photographic astronomy, so you really need to think about what you want to be doing, starting out. You are right that a large dob can be difficult to transport, but an equivalent scope on a decent equatorial mount would be worse. If you go for a 130mm or 150mm dob as suggested above then it can be reasonably portable, as they are often designed to be broken down and re-assembled. The alt-az option you have considered is often recommended for beginners, as the mount is simpler, reasonably compact, and can support a decent refractor or catadioptric device that will show you quite a lot. Again, though, alt-az will severely limit your photographic abilities. It is possible to achieve results with care and shorter exposures (there are some good examples in this forum) but you are really fighting against the technology rather than working with it. In terms of your targets, you mention solar system first and DSO afterwards. Again, there are balances and compromises to be made here. You correctly point out that a longer focal length (which you often get with a catadioptric scope, but you might also with a refractor) will tend to narrow the field of view available with a given eyepiece, and so will make it hard to view the whole of some deep sky objects. A fast (F/5) reflector will work better in this case. On the other hand, if you are interested in solar system objects then you will want to increase the magnification as much as the conditions allow, and a longer focal length scope helps here. You can perhaps see why many people eventually end up with several telescopes! There is often no single answer that will suit all the requirements. But you need to start somewhere, and to narrow down your choice, perhaps you can decide which of your wants and constraints are the most important and most urgent. I'm only a few months ahead of you, and I also came into it wanting to do visual and photography, of solar system and DSOs (oh, and possibly spectrography) but I decided to concentrate on visual to start, and decided that a faster newtonian gave me the best mix of targets for now - but I do have a back garden. The main thing is to go with something that you will use as much as you can, and will let you see enough to keep you interested, and then you will have a lot more to base your next choice on. Happy shopping!

I was surprised how white it looked when I observed it a few weeks ago (my first time through a "proper" telescope, 6" newt with a low-dispersion EP, no filter).

I assume you're talking about the line titled "7Timer Seeing"? I couldn't find anything on the CO site that explained it either, or the other 7Timer forecast lines. However, you can compare the CO data with its source on the 7timer website. The format is different there, but when I matched the two websites for my own observing location, it seemed that the general rule for all the lines on the CO site is "the darker the blue colour, the better". For the seeing forecast, that would mean the lower numbers are better.

... which I would also put into the "anti-social" category (from an environmental perpective at least). I think the other factor might be an increasing trend towards individualism over the years. For example, when I was a boy, there was an unwritten rule that you didn't light up a bonfire before dusk, because of other people trying to enjoy their gardens, dry washing etc. These days it's pretty commonplace to see bonfires and barbecues lit up at all hours. Consumer security lighting didn't really exist back in the day, but if it had then I think people then would have given consideration to the effect on other people before installing or using it.

... and seem to last forever! We also have neighbours that found it necessary to dress their garden with solar LEDs, and they keep going for hours after dusk. The battery must have more amp-hours than I'm using to power my scope!

OK. Well you've obviously found the welcome forum, there are some stickies there, and I expect you've found other forums by activity area. The "Activity" drop-down gives you access to several useful views and filters, such as threads that you have started and those that you have posted in. You can choose to follow individual posts and members, which will appear in standard views ("my activity streams"). You can even convert your own searches into bespoke "custom streams" that will appear in the same menu. If you prefer push notification to passive checking, you can even turn these into RSS feeds, and include them in an external news reader. If you're interested in buying second hand gear, you might want to keep a close eye on the For Sale/Swap section - there are sometimes good bargains, but they go very quickly.

Hi, welcome. Is that "figure out how this website works" or "figure out how astronomy works"? Do you have any specific areas of interest? Do you already have equipment?

Welcome. Looks like you should get some viewing in the coming week.

You will get less - if you have a fixed budget then opting for Goto will leave you less for the scope (OTA) and accessories. If you were viewing from a dark site then you would probably receive advice to get the biggest dobsonian you could afford. But there's no advantage in having a bigger bucket if you're going to struggle to find anything in the first place. That's the trade-off you need to decide, and for a beginner I think it's important to be seeing stuff early on. And I'd support Cosmic Geoff's mention of the RACI finder. I linked to a "straight through" model, but the RACI has the double advantage of (a) showing the sky as it appears in most sky charts (the other models are reversed L-R, up-down, or both!), and (b) saving you from contorting your neck into difficult positions. I'm waiting on a RACI myself (currently out of stock, like many items at the moment). Unfortunately, they are also more expensive than straight-through types.

There are folk who manage surprisingly well from city centres. In many cases the problem isn't so much seeing your target but finding it in the first place. In polluted skies you are going to struggle with star hopping because you will have fewer reference stars to guide you. Compounding this, a beginner scope will likely come armed only with a basic "red dot" finder or perhaps a 6x30. Substituting a larger finder will help with the hopping, but the extra weight may either throw the scope off balance or exceed the overall mount limit (especially if you start to upgrade eyepieces). A Telrad finder is very useful, but again it's heavy. You might consider a computerised "goto" mount, which will help with locating targets, but be aware that they are (a) significantly more expensive and (b) don't do all the work for you - you will likely still need to do some manual finding. That sounds a bit gloomy, but as I say plenty of people do manage well in cities. Another point is to pick your targets sensibly. Don't expect to see M33 from a balcony window (and now I know that someone is going to reply that they did just that). There are resources aimed specifically at the urban astronomer, like this book and this observing programme . Good luck.

This is a recent thread asking about a first scope for a 14-year-old, some of the responses may also be of interest to you.

Well, when "they" start planning the next incremental advance on the largest ground-based telescope (probably to be named something inspiring and inventive, like "The Really Quite Humungous Telescope") the one thing you can be sure of is that they won't be siting it in south Wales 😭. As someone who has only taken up practical astronomy in the last year (and also living in the southwest), I feel lucky in retrospect to have had those fabulous clear spells earlier in the year. I agree that if I had only just received my order from FLO I'd be pulling my hair out right now. The other factor I would suggest is that the degree of frustration will likely be proportional to the amount of faffing involved in setting up your kit for a "speculative" evening, when the forecast is ambiguous. In my case, I have a Bortle 4 back garden and an undemanding scope; if I had a 10-inch and needed to travel an hour to a dark site each time, then I guess my patience might be tried quite a bit more. As others have pointed out, there are some hobbies that are suitable to be the only call on your time, but observational astronomy in the UK is probably not one of them. (surprised that none of the folk detecting meteors with radio antennas have chipped in yet) Hope you get your mojo back before you start listing stuff 😀

Welcome. A SW 200 is a very decent scope for a beginner. Many have achieved excellent imaging results with smaller scopes, but as ollypenrice says, with imaging the mount is very important. You will have a bit of a learning curve if you're starting out with an EQ mount and wanting to go straight into imaging - are you completely new to the hobby? The good news is that there is masses of information in this forum. Have a look at the beginners' imaging section in particular, and check out the sticky threads.

Recent purchase of an 18mm Starguider has taken the last spot in my case, so my options now appear to be: (a) you have no room left. Stop buying stuff. (b) you have no room left. The next piece you buy will have to displace whatever you use least. (c) you have no room left. Buy another case, so that you have somewhere to put that next purchase.

Welcome, So according to their website this is a 76mm aperture, 700mm focal length reflector, i.e. around F9.2. As reflectors go, this aperture is very much on the small side, so the amount of light you can gather will be limited. But you will still be able to see things with it, though you may struggle to see fainter DSOs, especially if you don't have access to darker sites. Planets and the moon may be more successful. You mention getting a 23-30mm eyepiece, well 30mm would give a magnification of around 23, and 23mm (if you could find such a beast) would give magnification around 30. This would be better suited for larger DSOs or perhaps the moon, but planets will require greater magnification to see any details. The absolute maximum magnification is normally around twice the aperture in millimetres, so about 150 in your case, under perfect conditions. In practice you are unlikely to be able to push it to that. The suggestion of a decent zoom to start with is a good one, either the Sybony mentioned or perhaps this one which is very decent if you can stretch to it. Provided you're planning to stay with the hobby, money spent on reasonable eyepieces won't be wasted as they are pretty much usable with any scope.

Not brand new here, but I've only just noticed this thread. Overall, I've found this to be a massively useful and inclusive forum, hosted on a very capable platform. If I had one request for an enhancement (assuming that it's not already a feature that I've missed) it would be the ability for a user to set a single switch that would cause every forum view to default its sort order display to "Start Date" rather than "Recently Updated" (which is the current default). As it is, the first thing I do whenever I switch view is to re-sort the display.

There have been a few before you who have wondered the same thing, as you might imagine. This thread was from someone with different kit, but the advice is pretty generic and worth a read. Generally, probably better to try things out with what you have before you decide you need to splash the (more!) cash. +1 certainly for "Turn Left at Orion" if you can get hold of a copy, and it will give you something to read while it's raining 😂. If you can't find it, then you can get some of the information in the book on their website.

Welcome, you'll find that no question is too stupid here 😀 but the search function is pretty good, and you may find that your questions have been answered before you've asked them. Good luck with your Skyliner.

Ah yes, another disadvantage of the current lead times for new starters is that agonizing "what else should I buy so I can hit the ground running?" period while you're waiting. I had the same experience. There are several threads along these lines, but this is a current one that you might want to follow, and if you haven't seen it already, and then this is the sticky thread on eyepieces starters (but it's a longer read). There are also some good comments here. If the scope is primarily for yourself, and you're a patient type, then "not planning on getting any accessories until I start to use it and to understand it a bit better" is probably the best approach. One person's essential accessory can be a nice-to-have for someone else, and there will be plenty of calls on your cash without splashing it needlessly. Use your waiting time to browse through some of the threads in the beginners' section and get familiar with some of the possible deficiencies that you might want to correct with a purchase, then when you get going you'll know better what to look out for, and what you could do about it. And if we ever get any clear skies again (if UK) start getting yourself familiar with the layout up there, if you're not already.

I have that one, I find it very useful and I've been impressed with the performance. The FOV is narrower than some of the wider field fixed EPs, and as noted above it reduces as you zoom out, which is the opposite of what you might expect. There is another Hyperflex zoom with a slightly longer range, though I believe opinion was that the 7.2-21mm was slightly superior.
