On this picture you can see the difference by using more exposures to compose the very same field of view of the latest post.

This picture is a work in progress, i will add a lot of more exposures next days. This is composed by 13×180 sec L filter, 7×180 of R, G, B filters, 4x dark frame at 180 sec, for a total of  a little less than 2 hours of total exposure time.

After booting openwrt in the yesterday post, i found some problems with openwrt in routerboard 450g. The three more important and evident issues are:

• OpenWRT don’t see the NAND flash at all
• OpenWRT see only 128 MB of RAM instead of 256 MB
• OpenWRT don’t see the five Ethernet ports

After asking by email and fax mikrotik to release the kernel patches for this board, they send to me this patch against the 2.6.27 kernel: Mikrotik patches

WARNING: Mikrotik send me another mail saying that the yesterday patch has an issue, so, they send me a new one fixed. Thit is the Mikrotik kernel patch fixed
