Ladies and Gentlemen:

     In our capacity as counsel to Coaxial LLC, a Delaware limited liability
company, Coaxial Financing Corp., a Delaware corporation (collectively, the
"Issuers"), and Insight Communications of Central Ohio, LLC, a Delaware limited
liability company (the "Guarantor"), we have been requested to furnish this
opinion in connection with the registration statement (the "Registration
Statement") on Form S-4, filed concurrently herewith, with respect to the
registration of $55,869,000 aggregate principal amount at maturity of 12 7/8%
Senior Discount Notes due 2008 of the Issuers (the "Exchange Notes") to be
offered in exchange for outstanding 12 7/8% Senior Discount Notes due 2008 (the
"Original Notes"), which Exchange Notes will be guaranteed (the "Guarantees") by
the Guarantor. The Exchange Notes and the Guarantees will be issued under an
indenture relating to the Original Notes and the Exchange Notes (the
"Indenture") among the Issuers, the Guarantor and Bank of Montreal Trust
Company, as Trustee.

     We have made such examination as we have deemed necessary for the purpose
of this opinion.  Based upon such examination, it is our opinion that when the
Registration Statement has become effective under the Securities Act of 1933, as
amended, the Exchange Notes have been duly executed and authenticated in
accordance with the Indenture, the Indenture has been qualified under the Trust
Indenture Act of 1939, as amended, the Original Notes have been validly tendered
to the Company and the Exchange Notes have been delivered in exchange therefor,
the Exchange  Notes and the Guarantees will be validly issued and binding
obligations

 
of the Issuers and the Guarantor, subject in each case to the effect of (i)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights of creditors generally and (ii) the
application of general principles of equity (regardless of whether enforcement
is considered in proceedings at law or in equity).

     We express no opinion as to the applicability (and, if applicable, the
effect) of Section 548 of the United States Bankruptcy Code or any comparable
provision of state law to the conclusions expressed above.

     We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the Federal laws of the
United States of America, and the Limited Liability Company Act of the State of
Delaware.

     We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the reference to our name under the caption "Legal
Matters" in the prospectus included in the Registration Statement.


                              Very truly yours,

                              COOPERMAN LEVITT WINIKOFF
                                LESTER & NEWMAN, P.C.
