This is a die-cut foam insert for the Nexstar 5 made by JMI for their polycase and also fits the Celestron deluxe Hard case. You could also use this for other cases or make your own. Unlike cube/pick foam this insert fits the Nexstar 5 like a glove. It looks and functions much better. Original cost from JMI was $60. Selling for $30 + $10 shipping 48 state US. I have much feedback just ask. I also have a New Celestron hard case for sale on Astromart.
