Cheap ways to keep a dobsonian outside all the time?

Recommended Posts

Hi

 

i was wondering do people leave their dob outside all year round? I struggle moving it from the garage because of the weight and also steps plus a small door I have to try and get past. I was just wondering is there a solution where I can have it permanently set up or at least stored outside instead? I was hoping to not buy a shed or anything like that but maybe like a storage box of some sort? I saw there was a 24/7 cover would they work yearly? I would really like to find a solution because it’s stopping me from using the scope 

 

thanks

Hi Ollie,

 

Maybe you can use something like this near to where you would normally set your telescope up, It would be small enough to keep on the boundaries of  your garden possibly between bushes or something so that it is not imposing your view of the garden.

It will provide all year round protection from the elements and you could look at running a low voltage heater at times of the year time to keep moisture down and protect it all. both the top and the front open up for ease of access when the time is right. The cost for this is around £100.

According to the link you posted they guarantee that cover to work in most environments for 24/7 365 days.

Is your dob on a tripod mount, or standard chipboard base

Over time, the chipboard base will deteriorate if exposed to moisture

When use mine, put on a small waterproof tarp

Don’t know if this is justified but I’d be worried about a strong wind catching the telegizmo cover.

It wouldn't be a Dob if it was on a tripod John, but you knew that. :)

I have 10" collapsible, which is easy to store and transport

Out couple of times per month doing presentation primary schools, scout groups with my club

Olli has not mentioned what size dob he has

Interesting to find out

Yes, I would also be concerned about the scope being blown over in a gale.  Perhaps if you kept an eye on forecasts the scope could be stored in a shed etc on those occasions, so most of the time it would be ok outside.  

The issue of damp affecting the chipboard base is valid.  Perhaps the joints could be sealed with white mastic, or better would be to dismantle the base and seal the raw edges with PVA or similar, then the mastic after reassembly.

A shower cap each end of the optical tube, plus the dustcap would be good.

So with care, outside storage with a good quality cover could work ok.

I have a carry bag for the Ota so I think if I knew the weather was going to be really bad I would keep it in that and put it back in the garage

If the Dob has a chip board or MDF base, like my 10” Skywatcher, I’d make sure that any solution that you choose is very well ventilated. These materials and long term damp, don’t mix well.

Separting the OTA from the base for carrying is a must for door, steps etc. Putting some handles on the OTA helps.

Re. Wind. Store it in the horizontal position and use tent guy ropes to hold it all in place???

Shed / cover - use a low garden storage box for the OTA and just carry the base (think that has a handy carrying handle and is more manageable than the tube). These often double as a handy bench. 😁

I could have just said “like John says ^^^”! Would have save a load of typing.

Hi Olli

my 10" flex has been stored in this garden tool shed (see avatar) for five years or so and is as good as new. I put a dob cover over it just to be safe.  Fitted with caster wheels, makes it easy to set up.

Your Dob solid or flex

The pic I sent you was taken at a recent public viewing night on the foreshore with my club

In background is also an 8" flex dob with shroud

When out doing presentation school and scout groups, base and Dob sit on back seat of my SUV

Bit of rope from Dob to seat belt mount to stop rolling off the seat

I also use right angle spotting scope

Saves laying on ground when aligning   

I store mine in study, collapsed position

Respect to solar viewing

The hard plastic cover has an removable cap

The cap fits over the other detent for storage

Get some visual baader film, and cut a small square, and sticky to underside of hard plastic cover

Leave spotting off to avoid accidental viewing  

The attached pic was taken of solar eclipse several years ago, with my mobile phone held to eyepiece of my Dob, with the Baader film

 

Cheers

 

John

I’m ok carrying as I have a bag for the ota the main problem I have is the base as I just find it heavy and awkward plus I have to struggle getting it through a small door then a step which doesn’t help so if I can find a way to maybe just store the base outside. I didn’t really think this through when I got the scope. Maybe I’m just a weakling 😁

I don’t want to hi jack this thread but can you tell me if your dob came with the motor drive or is it an upgrade ?

The motordrive was used on the focuser. But have since upgraded to a lecerta dual focuser. Which is a good upgrade.

Thanks for the info but I was more intrigued with the guiding system which I have not seen before. Was it a stock item or an upgrade kit ?

I made it myself. It's still manually moved in az/alt . but so much better than std .it's a joy to use and very precise also very smooth. I think someone in the USA makes a similar setup but it costs around £300.I believe. It cost me around £50 for everything. If you look on youtube and type in zlomotion dobsonion. You'll see it .but mine is more stable than that setup.

Hi Paul,

Thanks for the explanation, you have certainly made an excellent job of the upgrade as it looks very professional.

Maybe you should go in to business making them 😀

Regards,

Maurice.
