The only critical dimension is the spacing of the Lunt and Kunming OTA's. The 3-inch PVC loosely secure the step-up / retaining ring. Ring serves as a retaining ring to keep the ERF in place three 10-24 grub screws threaded and glued into To 79mm to form a ledge against which the Lunt ERF rests. of the sky-end of this tube is machined out The 3-inch tube's diameter must be turned down to 87-88mm to pass through The length of the coupler will need to be adjusted to allow the proper spacing of the Lunt and Kunming's optics. The 3.5-inch coupler that connects this 3-inch tube and the Lunt OTA needs to be opened up by a mm or so to permit the Lunt to fit inside snugly but not too snugly. PVC fittings connect the Lunt OTA (on the right) with a short length of 3-inch tubing modified to hold the 75mm ERF. "Where precision cannot be built in, build in adjustability instead."īoth drawings are approximately to scale.Ģ8mm is the distance from the Kunming's backplate to the front of the Lunt tube.ĭO NOT FOLLOW THIS LEAD UNLESS YOU KNOW WHAT THE HELL YOU ARE DOING!Īt best, you'll char expensive gear. By and by we'll see how almost aligned and damn near aligned compare. The difference between being almost aligned and not nearly aligned is huge. A PVC adapter provides a fixed point at the tail end of the Kunming, and the collimating ring's bolts tilt the Lunt ota from that fulcrum. A Losmandy 3-point collimating ring provides the push-pull, up-down, left-right nudges required. The Lunt etalon is tuned by tilt, so it is crucial that the Lunt OTA be mounted squarely to the Kunming objective. Fine detail, much finer than is visible behind smaller glass, flickers into view a frame or two at a time, but the overall impression is of a much softer image. Not too shabby for first light under hazy skies, no? There's a real difference in the experience of observing the Sun with lots of aperture and a generous image scale compared to observing it with a much smaller 'scope. Here's some of this morning's take followed by some sketches and notes about the instrument: Today, the temperature of the PGR Chameleon did not rise in fact, it was operating about 10☏ cooler than usual. Encouraged, I finished a PVC connector to mate the Lunt OTA to the Kunming backplate, retired the Lumicon ERF in favor of a 75mm Lunt ERF, and simplified some of the mounting hardware. I saw fine detail and low contrast - and a ton of heat at the Lumicon two-part Energy Rejection Filter which was too hot to touch for some time after use (I wonder if I had its elements reversed?). Yesterday, I fit it all together and managed clear enough images to verify spacing. Iteration 2.0 uses the same Lunt components (tube, internal etalon, and focuser) behind a 152mm Kunming objective. The 90mm Frankenscope was so successful that I decided to push things further.

I won't explain in details how each software work (that would be way too long) but instead I will focus on the general workflow. In this Instructable, I will give step by step instructions.

Then, using open source and free software, we'll pre-process them, stack them, optionally de-rotate them and finally post-process the stacked image. In order to get a good image of the planet, we will have to take a lot of photos and average them.
If you zoom in a few hundred times on this star, it will appear to be boiling, stretching,expanding, etc.īecause of the turbulent atmosphere, every picture you take will look different and mostly featureless. We've all seen stars twinkle when they are close to the horizon. This is what happens when layers of air don't have the same temperature. Then, there is the issue of atmospheric turbulence. You will have to zoom a lot to be able to see any details on their surface. Here are a few reasons why: First, they look really tiny.
