New from Antares - Female Maksutov thread (visual back) with 1.25" twist lock eyepiece holder # SCT-TL
- Features an M44.5x1 female thread for attachment to many Maksutov telescopes on the market. See more informtion on this below.
- Features twist lock mechanism with knurled ring and compression band to firmly hold 1.25" diagonals and other accessories
- And that's not all. Unscrewing the silver lock ring exposes a male T-thread on the lower black barrel, which conveniently functions as a Maksutov-to-T Thread adapter by itself. So you're actually getting two adapters for the price of one!
Includes 1.25" dust plug and rubber o-ring (place between adapter and male SCT thread of scope in case male SCT thread is longer than this adapter's female SCT thread; should not be required for most applications).
About Threads on Maksutov & Maksutov-Cassegrain Telescopes
Many - but not all - Maksutov / Maksutov-Cassegrain telescopes sold on the market by Orion, Sky-Watcher, and other companies have a male thread on the rear of the telescope with a specification of M44.5 (44.5mm nominal diameter with a 1mm thread pitch). This is common but this is NOT a standard. There are many Mak scopes on the market that also use a smaller T/T2 thread (M42x0.75) and there are several large Maks on the market that use a larger SCT thread (2"-24TPI).
We do not have compatibility information for all the Mak scopes on the market and cannot advise you if this adapter is what you need. If you are unsure, check with your telescope manufacturer or measure your telescope's thread diameter BEFORE you purchase this adapter.
Specifications:
- Maksutov thread specification = M44.5x1
- Female Maksutov thread length = 13.5mm / 0.53"
- Adapter length = 38mm / 1.5" approximately;
- Maximum diameter = 55.8mm / 2.2"
- Male T/T2 thread specification = M42x0.75
- Male T/T2 thread length = 5.3mm / 0.21"
- Total length if used as Mak-T thread adapter = 33.9mm / 1.33"
- Optical length if used as Mak-T thread adapter = 28.6mm / 1.23"
- Made of black painted aluminum
- Weight = 4.4oz / 125g
- Made in Canada
A Word About Antares' Product Quality
This is a brand new item from Antares. However, the machining and appearance of many Antares items can be far from perfect. It is not at all uncommon for their Canadian-made items to have improper anodizing, minor scratches or scuff or nick marks, or for the threads to be roughly cut or have sharp edges. These threads should work with most compatible accessories, but the connection may not be smooth or complete.
These products are well priced and very good for the money, but you may want to look elsewhere if you are looking for perfection or precision machining. If you decide to return this item because of this after purchase, we will be happy to take it back for a refund as per our standard return terms, but will not treat this issue as a defect since this is being disclosed and explained in detail here. That's just the way Antares makes their products.
