I spent the day Saturday working on my 10 inch dob. I took the mirror out and cleaned it. I put a catseye hotspot on it. And I was able to get the tube 95% flocked (It was previously 70% flocked). Unfortunately it clouded up so I had to return it to my basement. My basement is 16 feet tall so it's a few flights of stairs. 

 

After taking it downstairs, I came upstairs to eat and I had some weird flashing in my vision in my left eye. It lasted for 20 minutes then went away abruptly. Reminded me of those Jellyfish that put out colors to attract prey. I believe it was from lifting the tube and probably a big jump in blood pressure. But it went away when I checked my eye in the mirror by expanding my eyelid, so maybe it was just something in my eye. I have hypothyroidism, but it's fairly well controlled. But I know I don't have it fully perfect yet. 

 

So my thought is I probably shouldn't be lugging the 10 inch up and down the stairs anymore. However, I don't want to keep it in the garage with the cars especially as winter arrives. It's a shame to not be able to use it more. I know one issue is I don't do good breathing when lifting and I tend to hold my breath at first. 

 

I picked up a 6 inch F4 to use with my night vision scope and it works well. Yesterday I moved it in two pieces (porta mount out first and then the scope). So that is a good solution. And I can purposely start moving things in pieces rather than taking it all out at one time.

 

I was considering a 16 inch dob in the future, but now I'm thinking I may want to stay a bit smaller. Anyone else run into items getting too heavy for their health situation?

If you have room to store it in the garage, do it.  It will not cause the scope any harm as long as it doesn't physically get wet.  I've had mine in the garage for 10 years or so.  I use a hand truck to move it around.  There are various ways to add wheels to it.  Never give up!

Heck, I gripe about my 8" Dob being to heavy.  I move it from living room to back porch about 25 feet.  But I do have 3 or 4 steps.  I'm to lazy to take it apart.  I'll be 70 in a couple of months.  I would like a 12" but that is not going to happen!

I believe I have had a couple of vision episodes that you describe.  My first advice is to check with your Eye Doctor.  My Eye Doctor saw me after I had my first episode - it was on the same day, but the episode had passed.  After questioning me about it, he asked if I had migraine headaches.  I said yes in the past, but not recently or for some time.  My Doctor said he thought the vision episode may have been a vision migraine.  He seemed to know about these.  They can occur without any pain whatsoever.

 

As I said, first advice is to speak with your Eye Doctor.  I've had only one additional episode since the first one, and they were separated by a year or two.  The second was not so scary since I had my Doctor's explanation.

 

So, it could be something like that, unrelated to your strenuous activity, but consult your Doctor for an expert opinion.

I can confirm the apparent Eye Migraine diagnosis, as my wife and I both have them occasionally with exactly the same symptoms.  I had never heard of them until I described my occasional symptoms during my last eye exam, and immediately the eye surgeon told what was going on.  A twenty minute "power nap" was recommended to relax and resolve the symptoms.  Very distracting, but from what the doc said no long term problems.

Following a traning routine is good to help you lift your scope and for general health. Mostly for the later.

Can't speak to your symptoms, although I might check in with my regular physician as well as the eye doctor if I were you.

 

I can suggest (strongly) that you stop picking up your 10 inch dob.  Make room in the garage or maybe a shed, and put some wheels on it (hand truck, dolly, etc.).   I put caster wheels on the bottom of mine, and I never have to lift it.  It's not a perfect solution (the wheels are a disadvantage sometimes), but if I had to pick it up and carry it up and down stairs every time I used it, I probably wouldn't use it much at all.

Yes, see an eye doc....it could be a torn retina....which would eventually detach and require surgery that may or may not work and possible partial or full blindness in the affected eye.

Please make sure your eye doctor is an ophthalmologist.

Absolutely!!

 

And a good one. I had similar flashes @ a year ago, read up on it on the interwebthingy and called my ophthalmologist immediately as it was a potential sign of retinal detachment. He had me in that afternoon, examined my eye carefully for one of the longest 5 minutes of my life and said my retina is fine. The vitreous body that is filled with vitreous humor had partially detached from the retina and would bring no further harm as the tiny space would back fill naturally. He did say if it recurs I should get back in to see him again for a status check.

 

Hearing him say, "Your retina is fine" after those long minutes was well worth the $75. An eye doc in a box is likely going to cost that and more w/o having the medical chops needed.

I recently downgraded from a 10 to an 8 inch. At 71 the 10 was getting too heavy for me and was killing my lower back. The smaller base on the 8 makes it very easy to carry out at chest level. The OTA, is also easy for me now. I'm glad I made the change and now setup and observe more often.

My basement is 16 feet tall so it's a few flights of stairs. 

If my basement were this tall, I would find some way of making a telescope closet near the top of the stairs.

 

Walk down 5-7 stairs, open door, insert telescope, close door.

  I've been having (optic,  aural, or eye) migraines for about 30 years. When I started having them my Dr told me that they are not in the eye which makes sense to me because I can "see" a pattern of zigzagged light in an area of my vision which doesn't change with either or both eyes open or closed. Mine last 20-30 minutes no matter what I do, but I have never had a migraine headache.

    When I experienced my first optic migraine, I thought I might be having a stroke. I'm not sure how long it lasted, probably about 20 minutes but it seemed like hours.

I have been having visual migraines complete with the aura's since I was a teenager. The key is whether or not you see the images in both eyes both open and closed. 

 

Mine last 20-30 minutes and are followed by a migraine that lasts about 3 days. During that period, I have tunnel vision, a lack of energy and sensitivity to light and noise.

 

There are drugs that can help but figuring out what triggers the migraine is the big thing. Food, ( including caffeine, alcohol etc) sleep, fatigue are some possible triggers.

I had a similar experience in my right eye several years ago.  Mine was not caused by a migraine, I took a bad wipe out on a 12ft wave while surfing.  The eye doctor said to take it easy, no surfing till it gets better.  It took about two weeks to heal.  Lucky for me I observe with left eye, so it didn't effect my observing.

I think all this confirms I need a 30 inch dob permanently mounted in a roll off observatory. The wife is NOT going to be happy about this.

Flashing green light could mean the retina is detaching... Or that pressure was put on it. Might not be related to the scope.

I've seen green flickering light go on for a few minutes. 20 minutes is a lot. Pay attention to the size of your peripheral vision, and how many floaters you have.

I'm another Aural Migraine sufferer.

 

Mine start with a loss of vision right at the center as if I was staring at a bright light. Then the little zig-zags migrate outwards to my peripheral vision. It's a pretty cool light show but I could do without the headache that follows.

Luckily I didn't have a headache afterwards. It's the first time I had this happen. But with my thyroid issue I'm not surprised when anything weird happens to me now. Even though I have it under better control.

Interesting. The zigzag pattern is what I saw and lasted 20 min.

This sounds exactly like my ocular migraines.

Mine seem to be triggered by bright light.

They start off small, in the centre of my vision, as a fuzzy spot.

The spot then expands over time, with zigzag lines around the edges, sort of like a fuzzy rip in reality!

 

Like other people who've posted, the first time it happened to me I was quite concerned. I went to the eye hospital (was living and working in London at the time, so went to Moorfields Eye Hospital - oldest in Europe!) and they checked me out straight away, as the symptoms are similar to those of a detached retina.

 

I feel very fortunate because I have no pain, only the visual symptoms, which go away after a short while in a low-lit room.

    I once had a aural migraine on the golf course. It started right after teeing off on a par 4. By the time my cart partner had hit and I was ready to hit about 100yds from the hole, the center of my vision was so bad that I couldn't see the flag. Cory laughed when I asked him "where's the flag?". I don't remember any more about the incident because it was right after I started having them, but I do remember trying to explain what I was seeing and what it was doing to my vision.

 

Edit: I do remember Cory telling me the flag was just over the bunker and I asked "which bunker?".
