astrophotography backfocus 3d models

Covers and caps for some commonly used sizes in astronomy and astrophotography. I find that sometimes I am missing a cap and I was unaware of a good collection, so I decided to design my own and bundle them.There may be some slight variations between...

This is a flats panel for taking flats used in astrophotography. Simply insert the 5" EL Panel (circle) into the base, glue the insert into place. The cap should fit on snug. Use with a 9v battery pack. NOTE: The EL Panel will make a small...

This is a bracket engineered to attach a Canon EOS camera (proven to function with EOS500 and EOS550) onto a Celestron Nexstar 8SE mount via a Skywatcher 15cm dovetail plate, making it easy to capture astrophotography images using any standard...

... To assemble, simply insert the bolt, attach your ballhead (you may need a 1/4-20 to 3/8-16 adapter), and slide three trekking pole tips into the tapered openings. Perfect for capturing astrophotography images from remote wilderness areas!

I designed this bracket to mount my Pegasus Astro Powerbox Advance (PBA) to my astrophotography rig via a losmandy clamp. There are 8 screw holes for attaching the PBA using short M3 bolts or computer screws (I used four M3 x 8 mm hex socket head cap...

I made this thing to help me locate points of interest when taking astrophotography images. I found using the red dot finder works great for this but I could not find a thing to connect the camera and finder together. There are some hot shoe adapters...

This is particularly handy for studio work and astrophotography sessions. The dimensions of the box are 45 x 33.5 x 16 mm, which matches the NB-2LH used in Canon Rebel (350D) cameras and possibly other Canon models (view the third image). The...

I use a DSLR camera for astrophotography paired with my Explore Scientific ED102 APO triplet refractor telescope, which I've modified with an all-threaded imaging train for added stability. The challenge was finding an adapter to link the male...

On my highly modified OTA, I have successfully used six internal baffles: five with 3cm pegs and one with a 6cm version positioned near the mirror cell, which has been moved forward as part of an astrophotography conversion. Update: A new front...

The barn door star tracker in the photo is based on instructions found at [here](https://www.instructables.com/id/Simple-Manual-Star-Tracker-for-Astrophotography/). ...The OpenSCAD file utilizes and bundles my tubemesh library, which can be accessed at...

This innovative tool is essential for astrophotography, where precise focus adjustment is critical. The Bahtinov Mask is placed in front of the telescope's primary lens and creates a radial pattern within the observer's field of view. As the ideal...

Focusing aid for Astrophotography designed to be placed directly over the lens hood, doubling as a dew shield for astronomy applications. The device fits securely over the extended lens hood without being too tight. Field testing has shown it to work...

Clamps and Fine-Focuser for Samyang/Walimex/Rokinon135mm f/2.0 for Astrophotography Extra needed: M4 and 1/4" Screws: You can use longer screws 2pc M4x30 2pc M4x20 1pc M4x14 Nuts: - 9pc M4 - 1pc 1/4" hex Build together: Screw in all nuts and screws...

This astrophotography mount, also known as a barndoor, Scotch, or Haig mount, allows long exposure night sky shots by counteracting star movement. Learn more on Wikipedia (http://en.wikipedia.org/wiki/Barn_door_tracker). The displayed model is made...

You were looking for a complete system to make your Flats in astrophotography and well here it is! With about 30 hours of printing, some soldering and some cutting with a cutter you will have a superb FLAT box adapted for 80ED scopes for the moment...

... adhesive on *mine*, so that I can use a mid-sized 3D print surface as a magnetic cap. It works great with and without the film. It's also a good excuse to put some magnetic material on your calibration light if you are doing astrophotography.

This is a set of scope rings that fit the Takumar SMC 200mm f/4 lens--a popular lens for astrophotography. The scope rings' diameters have an extra allowance for adding adhesive felt to prevent marring. I printed mine on an Ender 3 using a Cura file...

Can be used for astrophotography or visual viewing of bright objects in daytime or the moon. The bahtinov mask can be used for focussing on a bright star. ...And the blank/dust cap can be used to remix some other pattern onto it if you want to use it...

(09/01/2020) Mark 2 - For Full Coverage great for astrophotography (see photos) Mark 3 - For Visual Astronomers who want an slide-able telrad shield so they can look down into the telrad at zenith. ... No adjustment is needed in the x-axis for a tight...

... celestron red dot finder in mind. **If it's a bit loose and you don't want to reprint it or modify it, I can suggest adding some tape to thicken it.** If you want to see my astrophotography (or say thanks :P), my insta is the same username as here.

One of the calibration frames used in astrophotography is called a flat frame. Flat frames are used to tell the image stacking software how to remove vignetting from the image. The most common method for creating flat frames is to cover the lens...

For astrophotography, M42/0.75 thread is generally used for APS-C and lower sensors. I started from https://www.thingiverse.com/thing:703383 but it has some plays even with 0.1mm layer height and several tries. I modified scad for 1. make it much...

Ocular hole is place to the main lense, because the Zoom / telephoto lense is unsuitable for astrophotography. The design is also loose enough to fit phone with standard protective case. There is also a place for a M4 nut to tighten the ocular,...

I am just getting into astrophotography. I know it can be expensive to buy gear and I don't know, well, anything yet. To get started and start learning I made a couple prototype isosoles barn door trackers, one mechanical and one motorized like...

Mine came with a petal-style lens hood which seems suboptimal for astrophotography use since I can't guarantee that the imaging chip will be aligned with the petals. So, I finally took the time to learn OpenSCAD and coded it up. Unsurprisingly, it...

The Astrophotography images are 60 second exposures, showing the power of a Celestron Edge HD11 working at F2 :) Link to Cuiv the Lazy Geeks video = https://www.youtube.com/watch?v=eJ9_14Jvenk&t=1032s Link to Tri-Bahtinov mask generator =...

The cover is specifically designed to aid in long exposure photography, a technique often used in low light conditions, astrophotography, or to create special effects such as 'smoothing' moving water. The viewfinder cover helps to prevent stray...
