My Rowan AZ75 w/Nexus II arrived (I will post pictures once my Berlebach ships from Germany). I am very happy with the mount. Looking forward to completing the setup once my scope arrives. I purchased the SmallRig after seeing your post. My only complaint with the mount and Nexus II is the length of the cables. I understand that they are long to allow the user to install the unit in various locations, but they are twice the length I need. I guess it is time to buy a crimping tool.

I started this journey planning on only purchasing a couple scopes. Here I am still waiting for my first to arrive, and now I already want four.

Besides the extra mass, I much prefer six diffraction spikes to four. As such, I have not long considered the Mewlon 210. This is good for my budget, so I will consider it a win. 😉

I should note that the other scopes I am considering are all refactors: Takahashi FC-100DZ, Takahashi TSA 120, or an Agema SD 120. I am even debating putting the deposit down on the Agema and then purchasing the FC-100DZ or the Mewlon 180C while I wait.

Thanks for the response. Glad to hear you are still pleased with it. I would like to avoid active cooling if possible, but could use a small battery pack powered fan if needed. Mostly hoped to keep things simple. I just started researching binoviewers. The Maxbright seem to be highly rated. I will keep that in mind for a future purchase.

How large does the temperature delta need to be to be a problem?

While I wait for my FOA-60Q to arrive, I have been considering what scope I should mount on the other side of my Rowan AZ75. Like the OP, the Mewlon 180C is one of the scopes I am considering. I am a new astronomer, and I live in the Northeast of the USA, so my main concerns are collimation and cool down time (the temps can drop substantially at night here). The former I can learn. Will passive cool down be an issue? Having owned the Mewlon 180C for a while now, are you still pleased with the scope?
