Bahtinov mask "Banana" spikes

My neighbour has many years experience of using PHD and he can't get anything. -

Yes I'm wishing I hadn't posted that image we tried every conceivable level of gain and low exposure. Just got a fainter image of the above. -

I've done that these past 4/5 evenings but I've always given up and switched to Polemaster. Its not in focus and it doesnt come into focus by the normal means. There have never been any stars showing in PHD's screen but as I'm new to this I didn't realise there should be. I have wasted the whole winter 6 month period over this. -

PHD won't hold a star at all. No stars show on the PHD screen and SharpStar is very poor at finding stars. -

I have the same issue with my GPCAM guide/finder scope. It was new 6 months ago. I have never seen a really sharp image with it. Is this likely to be a collimating issue?

No I have never heard of the pin hole in foil method. I shall give that a go though thanks. Tonight I have the moon to focus on so I was going to start with that before it got dark then move on to a star. I wasn't guiding when I swapped out the SD card. I obnly discovered it hadnt been tracking this morning when I downloaded the lights. So no I didn't reselect tracking. I don't know if the device went to sleep because as I say I only discovered this morning it hadn't been tracking.

Last night Sharpcap wouldn't work at all. A couple of star images on screen were very blurry so I decided to find a bright star and use the Bahtinov mask. Unfortunately Sirius is below trees by the time its dark so used Capella. I have grown to really hate the helical focuser on the Altair GPCAM . There werent even the expected 3 rays to centre, it was just a blurr. You turn the focusser to sharpen and the star image moves with the focusers rotation. Before you know it the star has drifted offscreen any way as the mounts not tracking at this point . Eventually my hands were so cold I had to give up on this and PA with P{olemaster. That done I did 2* alignment (when sent to the first star - Capella in the west the scope slewed towards the Plough. I manually centred Capella the went to 2nd star and Procyon was nearly centre frame. I them went to M86 and to a 30s exp. Huge trails. Mount clearly not working. I went into the synscan app and clicked on tracking and it showed the RA and DEC reading as they were changing. It had commenced tracking. After leaving it an hour taking 1min exps I came back out and swopped over the SD card to have a look how it was doing. The 1 min exp,s were fine. THis morning I have just looked at the second batch of lights after I had swopped out cards and the mount had stopped working - huge trails. Would it be expected that by replacing an SD card you have to ensure tracking is running? If there is such a thing as a guidescope with a rack and pinion focuser I'd be very tempted.

When you say making sure the mount home position is correct can you explain? I am very familiar with where Polaris will be in my garden and even setting up in a different part of the garden I usually have Polaris visible in the polarscope from my first guess. I have never used the hand controller hust the app and am familiar with that. It would be another learning curve starting with the hand controller. My neighbour who has 60+ years experience watched over me do the PA last night and was happy we had a good PA. Then a 30sec shot of M86 showed long star trails - the mount wasn't even tracking.
