I have a SV 80 ED and soon will have a SV 110 ED.
Can I view the sun safely and well w/o purchasing a Lunt or Coronado 60mm? Thinking of Baader products specifically.

Which type of solar viewing are you thinking of?

White light viewing uses a filter over the front of the telescope (like the Baader material) to reduce the visible portion of the spectrum to a safe level and eliminate the IR and UV. This allows fine views of sunspots.

The Lunt H-alpha scopes eliminate all but a very narrow slice of red light, the light of glowing hydrogen, revealing prominences. (They are invisible in white light because they are far too faint to see against the light of the entire visible spectrum that is allowed through.)

Adding a Baader filter to the front of the scope is an easy and safe way to get white light views of sunspots and inexpensive.

A complete Lunt solar telescope is a larger expense, but they are nice.

There may be ways to add the necessary blocking filter and dedicated H-alpha filter to your scope, but, if so, it is not going to save you much money.

I'd recommend going the Baader route initially, and saving for a dedicated H-alpha scope in your future. H-alpha solar viewing is a lot of fun and there is often a lot to see.
