It is true its a tough target! The amount of bad luck I faced imaging this target is unprecedent. I attempted to image LDN 1235 back in June, the plan was to get 40 x 3 min subs for RGB and 60 for Lum. By the time I was on the B exposures my filter wheel was running into the mount. Although Redcat is small but the 2 inch filter wheel is relatively large especially when you rotate it to match the field of view in mind. I always had similar issues back when I was using the Redcat on the Sky Guider pro with targets close to Polaris. I need that Peir extension and riser blocks to avoid this in the future. I have processed the data I have the best I could and I used synthetic luminance to finish the job. Initially I wanted to continue addding the remaining integration but extreme bad luck with clouds and my battery power cable dying on me made it impossible so far! So I have decided to post my LDN 1235 and move on to my other projects. I might revisit again but most probably I will wait for next year when I am more prepared and with a longer scope!

The refractors!

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Dismissals Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
