Hello everyone, After impulse buying this 80mm refractor a year ago, being very underwhelmed and returning it, I've stepped back and done a lot of researching of scopes & astronomy (mainly online due to Covid19). Now that I have a little better perspective on things I'm looking to get my first "real" scope and would welcome some advice. A lot of things I read and seen seem to suggest an 8" DOB being a good beginner scope one can grow into, without breaking the bank. Thus I'm leaning towards the Apertura AD8 with a Barlow & maybe additional lenses down the road, but again I welc

Hi All,i hope you are safe n well,right then,i need advice on the issue of my rigel quikfinder base not adhering sufficiently( my opinion) to the sticky strips that came with it. I was wondering if that clear double sided gorilla tape would suffice? i would very much welcome your thoughts on this,thanks everyone Mark

Found various threads on here and other forums about flocking dobsonians/newtonians but couldn't find specific images of disassembly of the very popular SkyWatcher Heritage 130p flextube and flocking of the OTA. So having ordered some DC-Fix black velour sticky back material (can be got from various places including FLO) I thought i'd share some photos of the process from start to finish as it may help someone else in the future... Images below with notes... 1. Focuser and shield flocking This was the easy bit. A strip stuck inside the focuser, and just unscrew the

Established wisdom, or opinion parroted as fact?
russ.will posted a blog entry in Musings from The Fen Edge
I threw an opinion into the mix in the beginners forum the other night and decided I should expand on my reasoning here. Even somewhere as benign as SGL, you still have to remember this IS the internet. That means opinions repeated enough by people with large post counts, gain credence as fact among the rest of the forum. It does not hurt to challenge that, if only to get people thinking, as long as you do it in a reasoned way. So..... What got me thinking was the humble 8" Dob. For instance, I've noticed that the most recommended scope for a beginner is an 8" Dob; 10" if there's a sniff of th- 6 comments

After adding several large two-inch eyepieces and an Explore Scientific illuminated finder scope, my dob was quite top heavy. To remedy this, I added two 18” bar magnets to the bottom portion of the scope. Balance now seems nearly perfect! Got this idea from another post I read a while back on SGL!

In preparation for the upcoming "galaxy season", I have been busy re-organising my eyepieces across my eyepiece boxes. I am expecting to be using a mix of traditional and a-focal night vision observing. Therefore, I have put together a "mixed" case of eyepieces. There is a little space remaining just in case I need to swap in a couple more (but I don't tend to go outside will all my eyepieces in one go as they only get cold and unuseable, I prefer to leave a couple inside for a mid-session warm eyepiece swap-in! I have also created a new Sky Safari "brightest galaxies" observin

Hi everyone, I was lucky enough to get a 12" Skywatcher Dobsonian (305mm/1500mm) for Christmas. It shipped with a 10mm Plossl and a 25mm Plossl, both 52° AFOV. Finally had a clear enough night to try it out and I absolutely loved it. I researched a bunch over the last year so I knew this was the scope I wanted should someone want to get me a really sweet gift before I grabbed it myself. What I didn't research at the time was accessories and equipment, something I've been doing relentlessly over the past few days. I'll primarily be viewing in the backyard until I find a great viewing

Looking to upgrade from my current 4.5" EQ reflector to an 8" Dob. Not particularly concerned with brand and don't mind used condition provided all is in good working order. Bundled accessories are a bonus (EPs and filters especially) though not a must. Based in North Wiltshire and happy to drive to collect within reasonable distance (<1hr30).

This is probably my options as of now:I will definetly buy a 12mm BST Starguider A 2X BST Barlow( So thats 100x and 200x magnification) AND Either: 15MM BST STARGUIDER VS 25MM STARGUIDER My dobsonian telescope will include:A 25mm and 10mm Eyepiece . So the obvious awnser is to go for the 15mm BUT i ve read in reviews that the bst s have are noticabely better than the eyepieces that come with my telescope.So i am wondering, should i buy the 25mm or the 15mm BST? Also is it worth to barlow either 25mm eyepiece to make 12.5mm and ditch the 12mm i am definetly buying f

Hello guys,my 8" dob is arriving soon. I have trouble setting my expectations Since i have looked through my 3 " dob its hard picturing what i could see with an 8" one.i live in a light polluted city. Can i look at any dsos directly? How will they look like using adverted vision? What can i expect to see? Also which all around filter should i buy (2") to look at dsos and maybe some planets? Thanks Kronos

Hi, I have a skywatcher 200p dob and was hoping someone would be able to recommend an eyepiece with a wide field of view that would help finding objects and observing larger objects like the Pleiades. I have had a look at an explore scientific 30mm with 82° FOV, but was unsure if it would be good with my scope. Thanks Katie

Hope someone with more experience than I, which basically means anyone that has successfully collimated a Newtonian, can answer a couple of compound questions I have based on my first and only attempt at secondary collimation of my SkyWatcher Flextube 250. 1) All three of my secondary collimation screws were extremely snug before I did anything and I was only able to comfortably turn them counter-clockwise. Is this normal? Do I need to loosen all three screws first before I can properly start collimation? Should I be turning any screw beyond "snug"? 2) Before collimating, I placed

I wouldn't want to miss observing the Sun in a full-size 300mm filter, the detail compared to smaller instruments is such a joy to see. I do have an off-axis mask for my 300mm dob but not all the time. If daytime seeing is too bad for such a large scope, I'll switch to a smaller one, but the extra resolution and ease of spotting micro-detail thanks to the brightness is something I can't do without. A sheet of 500mm wide Baader fillm allowed me to craft this. I had enough left to cut several smaller filters. To protect it I made a storage box from cardboard o

Hi, I have a Sky-Watcher Skyliner 300P FlexTube GOTO which I am enjoying however after a period of no use the base has become very stiff. My fault, as it became wet not realising that the cover I had bought for it was not waterproof. Looking through the threads in here I found one which I followed to try to strip down the base however I have become stuck at the point of trying to remove the motor housing from the base after removing the 4 machine screws. I suspect that it is a combination of corrosion and the base material swelling which is preventing me from removing the motor from

Hello folks, for long I have been browsing the internet to find a suitable 10in dob and despite lack of reviews, I have decided to take the plunge with the Bresser Messier 10in Dobsonian. There was some doubt at first, especially when considering the popularity of similar scopes from Skywatcher, Meade and GSO. Even though Bresser is relatively new to the market, it has some clever features: 1. The massive 2.5in hexagonal rack and pinion focuser is very solid and the movement is smooth. Despite being only single speed, Bresser sells an a dual speed 10:1 extension. However, I find th

Hello stargazers, I've been stalking this forum for a good couple months now in my search for a telescope. My main focus will be the visual observing of planets and DSOs. I like photography might plan that later if possible (i'd like it to be). The skies where i live is somewhat polluted but not so much. I can easily spot most constellations with the naked eye if my drive my car on a hill outside the city. I was thinking about one of the models below. I'd like the get the best bang for the buck and minimize the risk of being disappointed and then wanting a more expensive tube later on. I'd

I picked up my new (and first ever) dob from Nottingham yesterday. Its a 20" f3.6 Lukehurst dobsonian. It has a 1/10 wave mirror. David Lukehurst gave a quick demo of the scopes features and answered my questions on collimation. Then it was time to dismantle and put all the pieces into my car. I had taken some duvets and pilllows to allow me to get everything packed in and there wasn't much room to spare... Everything was unloaded into my garage just before dark. Today I have been making up some wiring to connect the various "enhancements" that will increase my use of the scope. David had

I have a Skywatcher 200p Solid tube dob. I was curious if it is possible to fit the synscan system onto it like their truss tube dobs. Anyone have any insight on this one? It would just be nice to have since I live in the middle of downtown so finding some things isn't always as easy as it should be. Jon

Skywatcher 250PX Dob modded with Wixey alt/az encoders Well loved in excellent condition, stored in house. Mirrors light dust never cleaned (scared to :-) apart from rocket blower and MC Donald straws ) Secondary has steel washer mod, Base has lazy Susan mod, also levelling feet and wheels. Focuser is standard but will include self centring adaptor. Also included 50mm illuminated RACI finder. Also Baader laser collimator. Obviously due to size, collection only or can meet if local ish. Selling as going solar ... Any questions feel free to ask. ***ph

After opinions please ... I have a C8 that I use for planetary imaging / visual and a 250 px Dob for DSO visual . I haven't touched the Dob for what seems like forever and keep using the C8 more and more . I have about £300 Christmas / birthday money and keep thinking about selling the Dob to maybe fund something like a Lunt 35 or 60 second hand to throw on the AVX ? Have any of you been through this process and were you happy ? Cheers for reading

Thanks to those who contributed to my choice ITS HERE.... Woopeee. Of course it arrived yesterday just in time for the last bit of clearish skies... minus the box with the base in. That arrived today. Purchased from Amazon by OPTICRON TECHNOLOGIES who sell for Orion (US) and distribute from Holland so no nasty import surprises. The BIG box with the scope had been a bit through the mill being transported by FedEx with a few holes punched through the outer box but the inner box and scope were fine..well packaged. Waiting for the base gave me the chance to set the scope up on

We decided to build a shed to house our Dob, which was taking up way too much house space. As to design, @ollypenrice suggested that we build a large 'skateboard' upon which we should sit our shed. The board is made from a sheet of plywood onto which the wheels are mounted. The wheels we chose were the ones used for sliding gates (we have something similar on our roll-off-roof shed. Here is the shed on the rails. The rails themselves were mounted onto concrete, steel reinforced lintels which were concreted into the ground: A slot is cut into the skateboard to allow it to fit ar

I think I have just purchased a bargain. £550 for a Orion SkyQuest XT12i IntelliScope Dobsonian Telescope The product was used only for advertising purposes in my store, and the price is so low because has been unpacked-,full warranty, full accessories New,never,used- . To good to be true... I hope not I just snapped it up on AMAZON so at least not going to be a ripoff. Was looking for a 10" as thats how much I could afford but with a bit of luck it will arrive. Will be a bit of a change from my previous 8" SCT. Weather forecast over East Markham for the next 3 mo
