I believe I found a perfect way to hold my 70mm binoculars without any fatigue, and moreover in a very comfortable position. This work from almost horizon to zenith. Further, some report of these 15x70 Marine from Teleskop-Service.
You just need to lay down, I suggest on a camping mattress because it’s easy to carry.
You need then 2 pillows. One needs to be quite large (I use a 60x40cm one, thickness around 20 cm). Put one under the head. The other one (the largest and most important) between your forearms and your chest. Bring the pillow under your chin. You hold the binoculars with your hands and the binoculars weight will be completely supported by the pillow.
I did that while the camera monopod/tripod adapter was still on the binocular. I left it because it helps a little bit in some instances, but it’s not required.
Your eyes are now at perfect distance from the eyepieces. By adjusting intuitively your head on the pillow, or taking it off, you can observe from 90 to… very low, not 0 degree but close. Your hands will naturally follow the move by holding the binoculars closer or further from the prism and repositioning the binoculars on the pillow. You can move the pillow (which is not a cubical shape) on its different sides & lengths to adjust to the best comfort. A couple of seconds to adjust.
It has the advantage to be comfortable: you’re laying down, and the pillow even warms you up. You can eventually put a blanket. To look objects at the horizon, I use it hand held with my elbows on the knees, sitting on the mattress.
Actually I find this technique more comfortable than bending on my Mak, as I have no adjustable chair!
I tested first garden sofa pillows (that’s the best) but use also inflatable camping pillows. They have a very soft surface. I bought for 50 euros 2 inflatable pillows and a camping mattress.
You can use any pillow having some stable shape, retaining some form.
For backpacking you have for 50 euros this solution, which can together with the binoculars and all the usual gadgets be transported in a small day-trip backpack. You have free hands to make an expedition for a night up in the mountain (or wherever…)!
One default: you will get regular bouncing of the image due to your heart beat.
+ Comfort & absence of fatigue (if laying down is OK for your back)
+ easy and fast to implement
+ large range of vision
- view not perfectly stable (hand holding and heart beat)
I went twice to test my Marine 15x70 in that way. Bortle 5, elevation 18m at that place.
These are an awesome purchase. The materials and finish of the binoculars themselves is very good. You have immediately the feeling to have the quality you paid for.
I was scarred that the eye relief would be an issue as I have very long eyelashes. The entire FOV is visible without my eyelashes brushing the glass.
1h after sunset I was able to observe several DSO. The number of stars you see which are invisible with naked eye is impressive. Albireo is easily split.
I observed mostly the Milky Way. The Wild Duck Cluster (what a name!) served as starting point to find the brightest nebulae from Sagittarius: lagoon, Eagle and Omega fitting together in the FOV, trifid nebula. I could also observe the Dumbell nebula, M13 and the double cluster. I’m impressed how it’s easy to find all the targets, being used to the small FOV of my Maksutov-Cassegrain.
A lot of time just cruising the sky laying down. I promised to myself 10 times that I would just go on without opening my sky atlas to check what I see, and opened the sky atlas 10 times.
I had a look also at Jupiter, appearing way bigger than I believed it would be, with moons visible (I didn’t think they would be visible). Saturn just lets guess than something is strange in the shape, like a collimation issue, but the ring is not visible. As foreseen the moon is splendid. Some blue fringe is visible on it (that was when it was full, not yesterday when orange at low horizon).
One funny discovery: Brocchi’s cluster. The 6 stars perfectly aligned were quite surprising!
