Thanks for taking the time to share with others. I saw another YouTube video with only one screw holding the bracket on the GT81 which didnt look right.

Is Astro Pixel Processor still being developed?
Adrian J replied to GeekTeacher's topic in Discussions - Software
Just found this topic having been blundering my way through APP yet again without any instructions and glad to have found a potential alternative in Affinity Photo which I'm about to buy having read the opions here. I dont have a diploma in science but I am savvy enough to use Photoshop to a pretty reasonable standard to finish my files when they eventually appear in APP (with luck) because the processing tools in the right hand panel are nothing short of ridiculous in my opinion. APP is not a finished product, it's extremely biased towards people who have a high degree of technical knowledge in the subject and its not for me. And yes, I have seen the videos which are in no way a substitute for an in depth manual. Back to the original subject, Is Astro Pixel Processor still being developed? Yes it is and so it should be but reading the new release notes there's nothing to keep me onboard. -
Back focus and extension tubes

Hi all, Coming from a DSLR background I’m relatively new to astrophotography and still trying to get my head around everything. I recently purchased a WO William Optics GT-81 IV and ZWO ASI 294MC-PRO which are both mounted on an HEQ5 Pro. First thing I noticed was I couldnt achieve focus with the focus tube fully extended so I took the camera out, moved it further away by hand and found that I got a sharpish image about 2" inch further back so I bought a couple of 60mm extension tubes and believe these are needed as I'm not using a diagonal mirror? I've achieved focus using the extension tubes but often read about back focus and how critical it is. My images are okayish although stars sometimes appear to be a bit soft / bloated and this must be a dumb question but am I right to simply add the extension tubes or am I missing something regarding back-focus? And if I add filters or a flattener / reducer (which I've already purchased but not fitted yet), how do I achieve perfect back focus? Perhaps you folks can point me to some elementary education on the subject?

Power HEQ5 Pro from ASIAIR PRO?

No worries! That PSU looks good -

Thanks valleyman Did you by any chance look at the meter to see how much power your AZ EQ5-GT was using? -
Power HEQ5 Pro from ASIAIR PRO?
Adrian J replied to Adrian J's topic in Getting Started Equipment Help and Advice
Thanks Sealive and Davey-T, appeciated. It doesnt sound such a good idea to parallel the outputs and as long as I dont damage the ASIair Pro I'll try powering the mount from one output port. Spec for the HEQ5 Pro; 11 to 15 V DC 2Amp so the 12V output port at 3A *should* be okay in theory and I guess ZWO are just covering themselves not knowing which model of mount is being used. I'll report back when I've tried it. Thanks again to all. -
Power HEQ5 Pro from ASIAIR PRO?
Adrian J replied to Adrian J's topic in Getting Started Equipment Help and Advice
Thanks valleyman, I could see no logical reason why it wouldnt work but I'm no expert and wanted some feedback before potentially frying my ASIair Pro! I'm also going to power the mount from a separate 240AC/12VDC supply having previously got the flashing red light using a powerbank and already found that the EQMOD cable works just fine from the ASIair Pro USB port. Wondering if you could also let me know which Regulated Linear Power supply you use? I'm very grateful for your reply -

I'll follow the link and do some (more) digging. Thanks Kryptic and Dom, much appreciated Would still like to know if anyone has actually tried doing this and the outcome ... -
Power HEQ5 Pro from ASIAIR PRO?
Adrian J posted a topic in Getting Started Equipment Help and Advice
Hi Guys, I'm quite new to all of this and trying to tidy up my cables!! Does anyone power their mount from the ASIAIR PRO 12V ports? The Skywatcher website specifies Power Supply: 11 to 15 V DC 2Amp (Tip positive) for the HEQ5 Pro (which actually sounds a bit low) and each of the 4 x 12V ports on the ASIAIR PRO provides 3A max. To be on the safe side I was considering using 2 ports in parallel providing 12V 6A max to the HEQ5. I was also considering using the 2 remaining ports to power 2 x 12V 1.4A dew heaters. Stupid ideas? Opinions? Would very much appreciate some comments please -

Hi Vlaiv Apologies for getting in contact again but when I encounter a problem my brain goes into overdrive trying to find solutions and working through the valued information you gave me I've found relevant data in APP which is only seen by scrolling right on the information window. I'm still learning APP the hard way as instructions / videos are a bit scarce RMS (Registration RMS) and FWHM values for 30 light frames shown below but I cant understand how these RMS values relate to your comment that below 0.3-0.4" represents exceptional guiding and above 1" is below average guiding when worst value shown is 0.13. Does this make sense to you? -

Wow, that's really interesting. You've adapted the HEQ5 'head' to mount on a Berlebach planet tripod? If so, the belt drive will cope with the additional weight and it's the flex / instability in the tripod that limits the performance? Sorry to be a real pain asking all these additional questions and I'm so grateful for your replies.
