Yup yup... I think the first thing to learn before buying a scope is to learn how to maintain. Otherwise, buy the scope liao... Confirm the scope go haywire...

I think he means keep in a dry box.

Hi,

The 5" SCT or Mak would be the best beginner scope since it is small and does not require such a heavy duty tripod. It is easy to carry around.

For eyepieces, you can try out University Orthoscopic eyepieces or Televue Plossls as they are very good for the price; meaning you don't need to spend tonnes of money to get good quality eyepieces.

Radians are premium eyepieces.

If you are on a budget or just trying out this hobby, you may like to consider cheap but good eyepieces like plossls (Televue, Celestron, Meade etc) first.

If you have problems collimating or cleaning a SCT, just let me know.

You'll need more frequent collimation with a newtonian than a SCT, SCT holds collimation better. Btw I have a 5" SCT for sale if you're keen, if not i'm now considering trading it for another scope.

Orthos are good choice for planetary viewing, not too expensive and gives very good bang for the buck performance.

Well those have 60(?) deg FOV and 20mm eye-relief. Good if you need to wear specs to correct for astig. It imparts a warm tone to the image though. Not exactly value for money IMO. I would recommend looking at Nagler T6s, Pentax XLs (occasionally available here) and WO UWANS as better alternatives if budget is not an issue.

Cheaper but also great are Orion Stratus, Hyperions, Burgess Planetary eps.
