Hi all, I've just sort of stubble'd into short tube refractors. Started as a lark with a 70mm Celstron pre travel scope short tube, then in the "Quest for Aperture" I found an older Orion 90mm ST "Discovery" which was precluded with a lust purchase of an Williams Optic's Zenithstar 66 Petzval ED,,,,,,, yeah it popped up in the local classified's while I was waiting delivery of the 90mm. So, now I have the CA factor which I've experimented with using almost all the known filters of DSO, Planetary Bandpass, Polarize, & color filters. The infamous #8 with and without a polarize filter stacked seemed to be best in the 70mm & 90mm, the WO 66 being Petzval has almost no CA compared to the other two, so I'm working with the two a-fore mentioned short tubes, What success, if any, have any of you all had with CA filters and what would you recommend? Thank you in advance for any input, Slo

Morning all, guess I've been away for a while, new cases, one for my 100's and the dob, the other with some 82's and things for the SCT. EYEPIECE CASE FOR: Skywatcher Truss 10" dob w/ dual speed Crayford Williams Optics 100° & 110°, 5mm, 9mm & 20mm Zhumell 16mm z100 100° ES 5.5mm 100° ES 82° 6.7mm ES 34mm 68° 2" Barlow ES HRCC EYEPIECE CASE FOR: Celestron 8i SCT w/ GPS ES 8.8mm, 11mm, & 14mm 82° ES 20mm 68° ES 2X Focal Extender Baader Zeiss MK IV Zoom TeleVue 32mm plossl Celstron 6.3 F/R Orion Dielectric diagonal Baader-Zeiss T2 diagonal

Ok, I've changed around a few things to make room for a few things since last time I showed the case, changes are 3 useless TeleVue's are gone, the little Meade 32 is gone, the two X-Cels are also gone. New to the box are an ES Coma Corrector, which has been removed to make room fo the ES 100° 5.5.mm ES 82° 4.7 & 6.7, an ES 68° 34, and of course with 2" eyepieces I made another trip to the sporting goods store and in the flyfishing department I found these boxes then I trimmed the foam liner to fit the filters into and keep them snug. And as the 1.25 filter boxes I have shown before they are easy to open and remove the filters,,,,,,,,Much easier . Yeah, and the case will change again in the near future to make room for the 100° 9mm The CC, and 2" glass are for the 10" truss dob. and the 1.25's are for the SCT, Kinda weird, drove a dob one night, a week later I owned a dob. The use of the coma corrector has put some great resolution in the fov.

Ok, I've changed around a few things to make room for a few things since last time I showed the case, changes are the removal of the TelRad, the addition of a few more eyepieces and another diagonal, a Zeiss Prism.

Ya know, I don't think I've ever met an eyepiece case or set that I didn't like, It never seems to confrust my mind, did I spend too much or not enough,,,,,,, 128 pages of "Good Job!" edit: 129 pages of "Good Job!"

I put enough foam in each section to lift the filter up to the top so it won't shift around when the lid is closed and the foam has just enough traction on the filter to let you set an eyepiece on top and screw down a thread or two, then lift the eyepiece and spin the filter the rest of the way on. And to remove the filter it's as easy, most of the time I'll just unscrew the filter and set it back in the box, the box itself is so much easier to open than the original filter containers I'm surprised no one has done this before. Have fun!

Here go John, Plano model #3448-60 Proolatch Stowaway 6 compartment WWW.PLANOMOLDING.COM Sorry the pic isn't very good,

The filter cases I found in the Fishing departments of the local outdoor stores, Plano makes them, then I put a small piece of foam in each compartment to keep the filter in place, I'll get a photo tonight and post it here for you.

Thank you, The filters are DGM Optics, Lumicon, Thousand Oaks, Meade, & Orion. I began putting it together shortly after buying the scope and reading this thread, all 124 pages,,,,,,,,, In a way this thread was the inspiration, Again, thank you.

Morning all, I decided at the beginning of my astro observing obsession to put together a field kit type case, in other words what I would be using instead of what I would collect as a set. But as with any obsession comes the collecting of some things you don't need but like to look at. Here's the contents list because I'm not into imaging the display is more of an dismantled complexity. Top left, Agena illuminated reticle 20mm 70 degree, 6.3 reducer/flattener, ES 2X focal extender, Meade Super Plossl 32mm, old Tele Vue 8 to 24 zoom (my first real eyepiece 20 yrs. ago), Celestron 18mm X-Cel (that I got for public nights) Next row, ES 82 degree 8.8mm, 11mm, & 14mm then the surprise piece is the ES 68 degree 16mm (I call it the "surprise piece" because after I got home and opened the box I had no idea how small it was, long story but I was getting the 20 mm 68 degree and thought it would compliment the 68 degree set, never looked at it in the store, oh well, just like collecting old trains, you buy a set then open the boxes.) Bottom row, ES 68 degree 20mm, 24mm & Badder 8 to 24 zoom ( cause its got to be better than a twenty year old zoom, right?) The diagonal is an Orion dielectric mirror, The filters you see in the boxes are mostly Nebula filters, and like any filter used different manufactures have slightly different light bandwave specs so you end up with some that work better than others for certain DSO's. I put all my filters in these type boxes because it's extremely easy to open them and then screw the eyepiece a thread or two on with out even having to handle the filter instead of the original mouse trap containers they are shipped and sold in. I developed this technique when I was observing years ago atop a very tall chair and getting in and out of the chair to get another filter was a hassle. The case is an old pistol case from my first eyepiece and astro accessory kit, the center section that holds the eyepieces is a pre-cut insert from an Orion eyepiece kit, the side areas are fit with un-used pluck foam pieces left over from my OTA case, a Pelican 1630. You'll see the Orion box in the pelican case, that now holds the 9x50 IR finder scope Around the bottom leg of the tripod is stored the dew shield and the soft case holds handset & GPS, yup and that's where I hang the power tank with the red lamp on when I'm putting stuff away. I found that the strap that came with the power tank was very difficult to clasp to the end ports where it's supposed to connect, at the cap end is where it's directly clasp and the other end I put a key ring on there and clasp to that, much easier to release to thread it thru the tripod tray where it hangs when driving the scope. After getting set up the case acts as my table for setting my eyepiece case when selecting stuff and inside the case it's hid during public nights.
