Need 80mm eyecepie,for swift spotting scope #821.

To remove the top cover of your Brother Mademoiselle 821 sewing machine, you will need to follow these steps:

1. Unplug the machine and make sure it is in the off position.
2. Locate the knob on the top of the machine. This knob is typically located on the right side of the machine, near the back.
3. Turn the knob counterclockwise to release the top cover. The cover should pop open.
4. If the cover does not open, check to make sure that the machine is in the off position and that the knob is turned all the way counterclockwise.
5. If you are still having trouble opening the top cover, you may want to consult the user manual for your machine. The manual should have specific instructions for removing the top cover, including any combination of dials that need to be switched to a certain spot.
6. If you do not have a manual, you may be able to find one online by searching for the model number of your machine.
7. If you are still unable to remove the top cover, you may need to contact Brother customer service or a technician for assistance.

You simply need to choose if you prefer a better image quality or a smaller and lighter spotting scope. A spotting scope with a larger lens (60mm to 100mm) will have better light-gathering capability than a smaller 50mm lens spotting scope. This means that the image you see will be brighter and clearer. You will also enjoy a wider field of view. On the other hand the bigger the lens is, the larger and heavier your spotting scope will be. Larger spotting scopes are also more expensive.
Think about where you will be using the spotting scope the most. If you normally stay at a fixed location for a long period or don't need to worry about extra weight then opt for an 80mm to 100mm scope (if you can afford it of course). If you like to travel light or move around more than a 50mm to 60mm scope will suit you better. Some 50mm scopes can even be used without a tripod when needed.
