【商品説明】

光路長11mm±0.5mm　のスケアリング調整機能付M48延長リングです

どれだけ一生懸命ピントを合わせても周辺星像が決まらない･･･
原因として考えられる要素は以下のものがあります
・カメラセンサーの傾き
・接眼部の傾き
・光軸の傾き
・光学部品の固定時の傾き

Telescope Service社の提案は､このスケアリング調整アダプターを使ってカメラセンサーの焦点面に対しての傾きを調整することです｡

手順は･･･
0.まず1枚写真を撮り､星像の乱れを確認する
1.カウンターネジ(小ネジ)を緩める
2.星像の乱れている側の調整ネジ(大ネジ)を少し回す
3.再度写真を撮り､星像を確認する
　悪くなっていれば反対側に回して写真を取る
　納得のいくレベルまで星像が改善されるまで繰り返す
4.カウンターネジを締め､固定する

これでこれまでとは違ったクォリティーの写真が取れるようになります！！

接続方法
望遠鏡側：M48 メス

TS Optics M48 tilting mechanism - for perfect field definition
... allows perfect alignment between camera and a slightly tilted focal plane



Many astro photographers know the problem: one focuses as precisely as possible but in one or two corners, the stars are not pinpoints. Often, the result is a compromise by "tricking" the focus to a point where most of the image field has the best focus possible or cropping the image.

Some possible causes of this problem:
-- a tilted camera sensor (fragments of a millimetre are enough)
-- a tilted focuser
-- a tilted focal plane of the telescope (common at Newtonian telescopes)
-- tilted optical accessories by unprecise clamping

We have the solution:
With the TS optics tilting mechanism, the camera's sensor is aligned with the focal plane no matter what causes the tilt. You just have to keep the orientation of the complete accessory train.

And that's how it works:
The best way is a calibration by test images. Identify the "bad corner" in your photo and begin adjusting the TSJ.

1. Loosen the counter screws (the small setting screws)
2. Slightly turn the adjustment screws close to the "bad corner"
3. Take a second image. If the situation has become worse, turn the adjustment screw in the other direction until the image is satisfying.
4. Finally, tighten the counter screws again.

... and be pleased by a significantly higher image quality!

Technical details:
-- Connection threads: M48x0.75 - (female at telescope / male at camera side)
-- Back focus: 11mm (+/- 0,5mm - depends on adjustment situation)
-- Adjustment by three adjustment and three counter screws
