I have an ASI533 MC Pro (3.76-micron pixels) I use for DSO imaging with my EdgeHD 8 plus Hyperstar configuration. I've also used the ASI533 with a 2x focal extender for planetary. The sampling is an ideal match. I just bought an ASI678MC (2-micron pixels) for Lunar. The sampling is ideal at my native focal length and gives me a wider FOV. It also acts as my guide camera. I'm wondering if I would get better results using the ASI678MC with the 2x Barlow and bin 2x. Or similar/better results continuing to use the ASI533MC Pro with my 2x focal extender. I want a larger-scaled image of the planet with the best resolution possible. Yet I'm still not entirely sure I understand what would result in a better outcome.

Thanks for the reply. It's good to hear this from someone who has professional knowledge. I've heard conflicting and contradictory information on the internet from multiple discussions in my Google searches. It's why I chose to register and post to an Astrophotography group. Appreciate the help.

Thanks for the reply. What you've said about there being "no hard limit", explains why I've seen comments in Google searches that have multiple exceptions to the rule. I intend to match my current cable specs to the new shorter cables I'll eventually purchase. Fortunately, my objective is to shorten not lengthen the cables, which should avoid the cables being too long or bundled/coiled together. It's good to know that a "thicker, higher current rating" wont be an issue. Cheers. 🍻

Until now, I've been using the cables that came with the products I've purchased for my rig. I recently bought a power bank that gives me a variety of cable options. I'd like to make good use of them. The 12V DC cigarette plug that came with my Celestron AVX mount is too narrow for the power outlet on my Bluetti eb70 power bank. The loose connection is problematic and the exceptionally long cable is less than desirable. Several power cables that came with my various devices are too long. I've decided to find an alternative to the cigarette plug power cable since my power bank provides so many options. I also want to find shorter cables for my ASI cameras, ASIair Plus, dew heater ring, etc. I've come to find that the amperage of the cables is indicated by markings on them. All of them show to be 18AWG. From what I can tell by looking at some of the online charts, is that an 18AWG cable is a 5A power cable. This would make sense since the Celestron AVX mount has power requirements of 3.5 amps. There is also the matter of 5.5mmx2.1mm cable types. Not being familiar with the specs and finding equivalents, leads me to several questions, since I've heard many comments on social media about cables becoming too hot, batteries overloading, and components smoking. All of which I would like to avoid. 😆 As far as I can tell, to avoid "cables becoming too hot", I need to make certain the amperage of the cable exceeds the amp draw of the device. Are there any problems or issues that arise from cables being well over the recommended amperage? For example, my AVX mount requires 3.5 amps yet the AC adapter Celestron provides is a 5amp power supply. Would a 10amp DC cable connected to my Bluetti's 10amp DC barrel plug output port be problematic in any way? Or let's say, I used 7A or 10A cables that exceeded the 18AWG/5A cables that are being used with the other products on my rig. I'm trying to get the proper cable length as well as male 90-degree elbow barrel connectors at each end. I like that the cable that came with my mount has a lock screw on the barrel connector. It's a shame the cigarette plug is too narrow and the cable is so **** long. Ideally, if I could find a cable that is a 1.5 meter, 5.5mmx2.1mm, 18AWG/5A, 90-degree elbow barrel connectors, with a lock screw at one end, I'd have what I'm looking for. Is there anything I do not understand about compatibility? Are there any alternative approaches that might work? Are there any online suppliers with a large selection of cable configurations? I'm having trouble finding the ideal cable management approach. Mostly because these cables don't fall off trees and I don't want to use cables that have been custom made for the applications. Any insight you could share would be appreciated, thanks. 👍
