Next gear: EdgeHD 11“

Finally complete, my DSO small nebula and galaxy gear:

Scope
- 11“ Celestron EdgeHD with 2800mm focal length and 280mm aperture
- Celestron 0.7x Reducer bringing the f/10 down to a faster f/7
- Celestron Large T-Adapter to suit 146mm total backfocus
- self 3d printed tri-bahtinov mask with rounded slits - very precise diffraction pattern
- Celestron C11 dew cap

Imaging
Camera train with 55mm backfocus
- ZWO L-OAG off axis guider with Asi220 mono guiding camera
- ZWO 7x2“ EFW filter wheel
- ZWO Asi2600mm pro cooled mono APSC format dedicated camera

Focussing
- ZWO EAF autofocusser

Mount
- ZWO AM5 harmonic drive mount (needing a 4kg counterweight)
- The blus ribbon ties down the tripod to the ground, as it is a bit too light and at risk tipping over in a wind gust.

Dew heater
- Celestron 11“ dew heater ring - one of the neatest integrated designs I have com across, as it integrates into the scope tube

Control server
- AsiAir plus - fully controlling all attached equipments including cameras, guiding, focsusser & dew heater

Guiding
- depending on wind, seeing and polar alignment effort so far between 0.3-0.6“ guiding accuracy (same as with much lighter scopes) with OAG and Asi 220mm

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.
