Among the following three which one would you recommend for a backyard observatory. Are there others of similar kind/class that I am missing? Your help will be greatly appreciated in sorting this class of domes out, their pros and cons, etc. Regards

 

 

Note: Primary use-case is imaging from the backyard with a medium size setup

 

 

1. SkyShed Pod

 

2. SkyShed Pod Max

 

3. NexDome

 

4. Please list others in the same class...

What are your needs? (size of scope, type of observing/imaging, need for automation, etc.)

What is your budget? 

What are your capabilities? (building, technology interest, computers, etc.)

 

The PODMax is in a very different class than the other two. It's a large (12') observatory primarily designed for clubs, or private observatories housing very large instruments.

At this stage, let's not get into budget or other specifics; if there is any goal, that's imaging from the backyard and what kind of backyard dome will be best suited to achieve that goal. Hope that helps. Regards

Can Pod Max 'dome part only' be used in a backyard? I am looking at the limitation to zenith and any other limitations the other two might have? Regards

I have edited my first post to state the primary use-case, which is imaging from the backyard with a medium size setup. Regards

How about this place? I'd rather have a roll-off roof shed, so it doesn't look odd in my yard :)

If money is an issue then the Pod would be my choice,  but the Nexdome can be fully automated. I don't think that they have produced anything similar for the Pods. In addition the Nexdome provides better wind protection than the Pod can. The Pod is more fun to use if you are visual, looking at the sky through a slit is not much fun.

 

Finally, https://www.homedome..._6ft_ domes.htm is another option. I think he's still in business.

For imaging it is very hard to beat a clamshell design like Astro Haven's. 
https://astrohaven.c...s/7-foot-domes/

I don't have to concern myself with dome rotation nor syncing the dome to the scope, although I can always leave one side up as a wind block.

Price is a big concern with these; do you have a link to the prices? Regards

Here are some ideas to re-purpose/re-engineer some of the sheds/kids play houses; one option is to custom roll-off the roof, other option can be to custom roll-off the entire shed (rollers at the bottom edges I mean). Regards

Can someone post a link to rollers that can be used in following two scenarios:

 

 

1. Roll off the roof of a shed; rollers that slide the roof off

 

2. Roll off the entire shed; rollers that could go at the bottom of the walls

 

 

Regards

Here's what I got when I contacted them. My used 7' was much, much less. What's SkyShed want for their Pod Max?

7 Legacy white with one ring, D0700-047+D0703-003         $21,900.00;

12.5 Dash1, white with access door, D01210-002:                $44,900.00

My very preliminary plan for SkyShed Pod; your comments welcome...

 

 

Question: Is better to have spare deck space in front or back of the Pod circle in the shown scenario?

I have been looking at the PodMax v a rolloff. The basic PodMax is $14,995 which seems very fair. Hoping to hear from someone who owns and uses one.

I like the overall setup now. A couple of questions ...

 

- could the bay overhang the edge a little bit? In terms of supporting the bay you can get away with a only having support under 3/4 of the bay.

- Is there any need for the space to the right (SE) of the POD? Could you work with the same amount of space as at the top edge of the platform? I'm also assuming that you want to put the door on the bottom edge (SW)?

 

If you took the space away from the right and nudged the POD to the left you could get away with an 8' wide (x 11 long) deck which would reduce the cost of the wood for the deck. (8' decking laid cross ways instead of cutting 12' stuff)

 

I like the pier position. I would however not be married to the very center positioning of the pier in the deck. Give yourself a little lee way in the exact position of the POD over the pier and perhaps in the position of the deck with respect to the pier so you can fine tune the pier/mount position in the POD.

Thanks for your feedback; much appreciated.

 

 

I see I have created bit of a confusion about my plans. The red rectangle is the total size of the deck 10x16 which also houses the warming shed. Reason for such a design is underling geography of the backyard as shown below. Note: One can walk off the deck toward NE but the drop of the other sides is high.

 

 

I would like to avoid bay overhang since I might have to build an 'open deck', to use your words, atop that particular bay area and would like to have some deck space to work with.

 

 

S or SW may be a good location for the pod door; I left that space between the pod and warming shed for a walkway/exit off the deck. Sloping of the landscape below will explain this better. Rest of the space toward SW is mainly to have some room to walk around, enter/exit pod easily, etc. Space in front of the warming shed I am thinking may be used to setup a temporary tripod for occasional viewing.

 

 

One far fetched idea is to have three anchored spots in front of the shed for tripod based visual observings for occasional visitors where deck vibrations could be mitigated. Note: Pod will be dedicated to imaging.

This is a great advice! I have done bit of homework regarding this and I hope it will help others in deciding where to put the pier in the deck.

 

 

Note: SkyShed Pod template I used was  not up to spec so 1' squares don't exactly match the template (...horizontally) but you pretty much get the idea where you should put the pier in the deck in terms of having room to fine tune the placement of SkyShed Pod. Comments/suggestions welcome to further streamline this placing. Regards

Considering cold weather, what's the insulation difference between insulated walls SkyPod and NexDome? I know when dome is open during use, it really doesn't matter much in terms of insulation. In short, my question is more about in-use insulation, although you can also comment on close dome insulation efficiency differences between the two. Regards
