Carina Nebula - First Light with Askar FRA300

This is a first light image taken with my recently acquired Askar FRA300 OTA which I've paired with my ZWO ASI6200 camera that I have had for about two years. I've previously been using the ASI6200 camera with a Canon 200mm lens with good results but there were some issues with star quality around the edge of the field. I decided it was about time to marry the ASI6200 with 'real' telescope but to continue with wide field imaging. I like the specifications for the Askar FRA300 as when it is paired with the ASI6200 it provides a field of view of about 6.8d x 4.6d for an image scale of 2.6" / px. A slightly reduced field than when using the 200mm lens for a noticeable improvement in resolution. The FRA300 is petzval design as well which are designed to have a flat field out of the box obviating the need for additional field flattening or focal reducing hardware. From my testing with the FRA300 so far it is in line with these specifications. This particular image is taken with a 48mm adapter in the image train connecting the OTA to the ASI6200 filter wheel whilst I am waiting for a 54mm adapter to arrive.

The image posted here has been processed from 19 Ha subs at 900 seconds per sub. Image was calibrated with darks and flats and processed entirely in Pixinsight.

Image Revision B shows the new OTA mounted on my Skywatcher HEQ5 mount.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
Early dismissal 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.
