Please could you let me know the size of the pins? Would standard female jumper cables work or maybe JST Connectors? My original HEQ5 steppers came with what look like 0.5mm 4 pin JST type connectors.
-
I have 2 spare DRV8825's at home. I'll check the list if they work. My mind is shuttling between the CNCV3 and STM32 controllers.
-
yes, i've read and bookmarked it. What I need to figure out though is how to attach the wemos to the cncv3. There is not a single schematic to show what goes where, atleast I am not seeing the Idiots Guide to Getting it together.
-
would these items be the ones you recommended please? Wemos R2 CNC V3 anything else that i need to get please?
-
this looks like its right up my alley. I am a total dud with electronics, though i can solder well. Please could you send me a tutorial etc for this version? Thanks again.

Hi Malcolm, Are you the same Malcolm who's been replying to my HEQ5 blown board messages on EQMOD mailing groups? Either way, thank you for your detailed reply. Its definetly worth more than 2p. I will explore the OnStep too. The Gerbers for the shield PCB is available online (for the Arduino Mega Board), not just the schematic. I can print 10 PCB's here in Bangalore for 20$, so no more China We get all components here for dirt cheap prices too you can perhaps but 10 capacitors for a British penny here. Since its the rainy season here and a lockdown's been imposed until month end, I wont be able to get myself out to buy anything. I'll take a call on it and keep this thread going for a while Thanks again.

yes, i'd thought about it, but since a local friend had made his own DIY GOTO mount using AstroEQ (and that I am a dud in electronics), I decided with the latter. Since Tom is not replying to messages anymore, or the astroEQ forum is inactive, I am looking for anyone who can draw me a PCB Gerber file so that I can get it printed and solder the components myself.

Hi John, Looks like I came acroos your writeup after 2 years, ha ha. The motherboard on my HEQ5-PRO blew and I am planning to DIY the AstroEQ using Arduino Mega. I understand that you used Tom's board, but if you could kindly share pictures and your experiences in the past 2 years, i'd be grateful. TIA.

Hi Everyone, The motherboard on my HEQ5 PRO went bust a couple weeks ago and after trying everything to fix it and looking at the cost of a new one, I've decided to make myself a AstroEQ board based on the Arduino Mega. I would be very grateful if anyone here has built one and your feedback please. The original AstroEQ forum isnt very active.

Background: I flashed a 32GB SD card 1.5 years ago and installed it in my Pi3B. From day 1, the Astroberry was visible as a Wifi Network and I was able to connect to it using my laptop and mobile phone. I have never connected the astroberry to the home wifi. Yesterday: After a gap of 1.5 years i tried booting it up again and its not visible as a wifi network anymore either in my laptop or my phone. I connected it to my HDTV via HDMI and it works just fine. Question: How do i make it work as a wifi network so that i can use it through my laptop wirelessly? I have contacted Radek too, but just in case someone else can give me an answer. TIA

you're absolutely correct there. I just found out that the equipment profile selected was OAG (1350mm) while i was guiding with Finder Guider. My mistake..
-
i'll recheck all the internal settings. I actually did not change any including guidescope params. Mine is the standard finder guider. I'll check the next time i get clear skies.
-
the parameters seem to be almost the same. the guiding exposure was 3s to beat the seeing which is usually 1.5". I am myself finding it hard to digest.
-
Recently I had belt modded my HEQ5-PRO and last night i gave it a full run and i was absolutely stunned to say the least about the guiding results I achieved. I was left wondering if its even too good to be true! Below are Before and After images of guiding.

Hello Everyone, I am looking to purchase 14-16" glass blanks. Would anyone know of a reliable supplier in UK?

Comet Neowise from India
astrosathya replied to astrosathya's topic in Imaging - Widefield, Special Events and Comets
Great to know you've spent good time in Bangalore. I live in a place about 4 kilometers from Hebbal (the huge lake half way from the city to the new international airport). I hope you come back to bangalore and we could catch up. -
Finally I processed the Comet Neowise captured from Bangalore. Simple Set-up: Canon80D, Sigma 70-300 DG APOII @100mm F/4. ISO2000, 50x5s Stacked in Deep Sky Stacker Processed in Pixinsight. Lots of noise as I wanted to pull out both tails

Hi Everyone, I am thinking of re-starting mirror grinding at home. I used to grind by hand and in this method, when we use the 1/3rd off-centre strokes for hogging out the sagitta, the upper glass becomes concave and would be polished into a mirror. However, this time I'd like to build a Mirror-O-Matic or something similar and do not understand that if the tool is on top, how will the bottom glass become concave? Or am I mistaken? Please advice.

Hi Everyone, I am trying to setup the off axis guider in stellarium I've entered all details for my QHY5L II and checked the off axis guider box in the config. However, for the love of God I am not able to make the OAG red box appear in the display. No clue whats happening. My main imaging camera is a QHY9M. Any help will be appreciated.

HEQ5 Pro vs Celestron Advanced GT mount (cg-5)
astrosathya replied to neltek's topic in Discussions - Mounts
Dont go for the CG-5GT, especially if its a 2011-12 model. That was the final batch of production and 9 out of 10 mounts would be returned. The HEQ5-PRO any day. I've has both mounts. The CG-5 I disposed off within two weeks of purchase owing to faulty gears. The HEQ5-PRO i've had for 8 years and last week I modded it to a belt drive too. -
Thank You Carole. Its actually not difficult, but yes, a bit intimidating at the beginning perhaps. The only fiddly bit was unplugging the DEC motor wire. Otherwise much of it was a breeze.

Friends, I am back with a tutorial video on how to modify your Sky Watcher HEQ5-PRO mount or its American twin, the Orion Sirius EQ-G into a belt driven mount. The benefits of converting to a belt drive is that you don't have to worry about Backlash. The procedure took me about an hour to complete. Link is below https://youtu.be/PjDZiXaN5KM

this is correct, because of the filter wheel.
