Probably two or three times a year unless I accidentally touch the glass with my hands and/or eyelashes. In that case, I'll spray a couple/few pumps of Zeiss Lens Cleaner solution onto a clean microfiber cloth and gently wipe the lens. However, after each use, I usually blow off any dust/particles on the eyepieces with a blower tool [Opolar Battery Operated Air Duster] before I put them back in the case. I do this regardless if I see any dust particles or not just to prevent anything from building up on the surface [visible or invisible].

Thanks! It's a waterproof 'picnic' blanket that's pretty dense, so it stays where it lays. I live in a very humid region, so having a barrier in between the ground and the scope helps keep moisture from collecting on the equipment. It's my back yard, but I share the lake/pond with a few neighbors. They're all pretty friendly and respectful and leave their back porch lights off for me.

The reason my Takahashi 76 is up for sale

Good lookin scope! Is the objective oil-spaced or air-spaced? -

Here are a couple cellphone pictures I took of the Alpine Valley Rille with my 4" FC-100DF. Pardon the black-spot photobomb in the first image.. Cursed camera is flawed. -
Ethos 13, or ES92 12, or stick with my ES82 14, or ... ?
rkelley8493 replied to Size9Hex's topic in Discussions - Eyepieces
Here's a visual between the two, pictured below.. I had a chance to compare them, and the last thing that crossed my mind was the difference in FOV. They're both equally excellent performers, but the presentation is completely different. The whole 92º field can fit on the huge eye lens of the ES. The image just seems to float above it. The Ethos felt more like a porthole experience, like you are looking into a window to outer space. Other users have found it easier to view through, i.e. more consistent exit pupil. So I guess depends on your level of experience [depends on your style as well.. I prefer long eye relief EP's]. With practice you learn how to adapt your eye to the exit pupil in long eye relief oculars. Ones not familiar with LER eyepieces may have some trouble [like kids or others you may share with], but like any sport or hobby, practice improves your abilities. One thing to mention though, and it has nothing to do with the views.. The 12 ES 92º is much more massive than the 13 Ethos, almost twice as much. The 12/92º weighs 1017g vs 590g for the 13E. This could be an issue with smaller style manually tracked mounts. Just something to consider.. -

Thanks for the support, Mike! Nice to hear from you. 👋 😀 To add, the cursed lens shield on the camera is cracked, and it's a hand held photo. I try to capture what I observe with my cellphone, but taking a picture of an image with a flawed camera is never going to reproduce the actual image. Sort of like making a copy of a copy; it never comes out as good as the original. Maybe I should've shown my Luna-pics instead of Mars through a cruddy atmosphere. https://www.cloudynights.com/topic/694006-post-your-cell-phone-or-smart-phone-lunar-image-here/?p=10828247 -

My point is you can use extremely high magnification in this scope with hardly any chromatic aberration or image breakdown. The last few posts were mentioning powers over 200x and 350x, so I was simply showing an illustrated example. -

Check this out.. This cellphone capture is from last fall [Oct-Nov] with 4.5 Delos + 2x Powermate in FC-100DF. Magnification is 329x. -

Show us your dual scope set ups
rkelley8493 replied to spaceboy's topic in Discussions - Scopes / Whole setups
Kool! I didn't know you could do that. I've been eyeballing the AZ100 mount lately.. I should be able to pair it with my Berlebach Planet & Orion Pier Column Ext. 😄 -

Is that the AZ-EQ6 Pier Column Extension attached to your Rowan AZ100? -

I use a 1.8x GPC for Refracting & SC Telescopes [Baader T2] with my binoviewer. There wasn't enough inward focus travel when I attached the GPC to the nose of the binoviewer, so I ended up attaching it to the T2 prism. This configuration required a ton of outward focus travel because the GPC is so far forward in the optical path. The closer the GPC is to the objective in the light path, the further [outward] distance you'll need to reach focus. The further the distance of the GPC from the light path, the more inward travel you'll need to reach focus. This was no problem in my SVA-130T w. 3" Feather Touch, but in my FC-100DF, the draw tube length on the focuser wasn't long enough. To get around this, I ended up getting the Baader Tele-Kompendium set of extension tubes & adapters [see bottom picture]. This allowed me to attach the T2 GPC within the extension tubes for a flexure free optical train and gave me enough back focus to work with. Here are a few illustrations. This picture has the GPC attached to the nose of the T2 prism [requires a lot of focuser distance]. I had to pull the gpc halfway out of the focuser to reach focus and spot the weight due to flexure

Here's my dual rig, but I've only used it a handful of times bc it's a lot of work to setup & deploy -
I'll contribute a couple. These were taken a few days ago through my Google Pixel 2 [Night Sight mode] with my Takahashi FC-100DF, AP MaxBright, and Pentax 10 XW. I increased the contrast in pic 2.. I wasn't sure which I thought looked the best, so I saved both.

Explore Scientific 12mm 92° has arrived
rkelley8493 replied to michael.h.f.wilkinson's topic in Discussions - Eyepieces
Aw man 😧 That's crappy news.. I was hoping they'd release an 8mm 92° to fill a void I have with this focal length. I'd be more likely to purchase a new ES 8mm 92 than I would an 8mm Ethos, but it looks like I may not have the luxury 😕 -
Explore Scientific 12mm 92° has arrived
rkelley8493 replied to michael.h.f.wilkinson's topic in Discussions - Eyepieces
The 17/92° is the heaviest eyepiece I own as well, though our eyepiece collection is similar. From most massive to least, mine goes something like this: ES 17mm 92° - 1159g TV 21 Ethos - 1021g ES 12mm 92° - 1017g TV 31T5 Nagler - 1000g TV 17T4 Nagler - 726g TV 22T4 Nagler - 681g TV 4.7 Ethos - 590g TV 3.5 Delos - 499g TV 6 Delos - 454g Pentax XW 10 - 390g
