Hi,
I don't necessarily agree with some of the advice you have been given. I own a Televue Paracorr, 2 Televue Powermates, a 2" barlow and a 1.25" barlow and to be honest I don't think you need any of those things at the moment. In an F5 Telescope I consider a Paracorr a very marginal piece of equipment. I have one for my 18"/F4.5 Telescope and only use it with 4 eyepieces out of at least 10 that I have. (31mm Nagler, 20mm Pentax XW, 17mm Nagler and 14mm Pentax XW). I don't use the paracorr with any eyepiece in my 10"/F5 telescope or with any eyepiece in my friends 25"/F5 or his 20"/F5.
I think your existing eyepieces are pretty average and not suited to use in a telescope with an F5 focal ratio. Unfortunately the eyepieces supplied when you buy a telescope are usually cheaper ones which don't work well at F5. Telescope dealers will always sell you what they carry in stock. Meade dealers will sell you meade eyepieces. At present Meade don't have any eyepieces that I would want to own and use in an F5 telescope.
I would start from scratch (sell every eyepiece you have)and start building a quality eyepiece collection you can use in any telescope you have now and progress to into the future.
You could consider buying second hand to save some money,
The telescope you have is a good one and will give you a few years of great use before you feel a need to go to something bigger and better.
I would consider building an eyepiece set along the following lines.
Low power = 30mm Pentax XW or 27mm TV Panoptic
Med Power = 16mm Nagler T5 or 13mm Nagler T6
High Power = 10mm, 7mm and 5mm Pentax XW's and a 8.5mm Pentax XF
You could also add a high quality barlow at a later stage if you felt there was a need.
Unfortunately there's quite a few dollars worth of eyepieces listed above and you may want to convert over in stages to suit your budget and any financial constraints.
Cheers,
John B
