Beautiful clear night last night, so despite being a near SuperMoon, footy field flood lights on, and it was a week night, I went for a couple of hours of Ha on NGC6188.
Pretty happy with the field flatness. This was with the Orion Flattener on the TMB92SS. Think I've got the spacing pretty close to right now. Maybe not perfect, but close.
Tonight is looking promising too, so will hope to add some OIII and SII.
Larger size here.
