Budget but good refractor for a Hershel Wedge?

Post by barnstorm »

My astro budget is over the limit and my credit card is whimpering under the couch thanks to my camera addiction BUT....

I have never owned a Hershel Wedge before and was thinking I might try to start collecting used bits until I can afford a good wedge, hopefully, next year.

Any recommendations on a good refractor for this use? I do visual and outreach but also a good deal of imaging.

I have a 90mm Mak with a glass filter already so I was thinking of something in the 100+ size range.

Thank you for your feedback!

What budget are you looking at? Where are you located?

Batavia (Cincinnati) Ohio.

I sort of don't know what budget I am looking at, that is part of my question I guess. I am HOPING something in the sub-$700 range.

I noticed Explore Scientific AR152 Air-Spaced Doublet Refractors are about a grand and a saw one used for $700 but he would not ship (local pickup only). And I don't even know if that would be a good refractor for a H-wedge.

I love refractors up to 4 inches but beyond that I find the cost and weight issues don't favour them. If the goal is for very large aperture white light solar imaging, then nothing really can beat the solar Newtonian approach. A 200mm Newtonian is superb value. It probably costs about the same as a Baader Herschel wedge, which is likely what you would need to use with a large aperture refractor.

That is exactly the kind of thing I need to know. Thank you!

A few people on here use that scope, they're OK. You will need a good mount for it though, 6" fracs are heavy beasts!

Probably an 102ED doublet like the SVBONY one would be good enough? (they sell direct)
At this size and cost point, you can use a Herschel wedge or a Quark without fuss, AFAIK.

N.F.
