Hi all,

I wanted to buy my first narrowband filter. I decided on a 7nm Ha filter. Among the options, there were the Baader 7nm and the Optolong 7nm. I chose the Optolong even though I heard that the colour ones are Astronomik copies. However, I searched some comparisons between the Baader and the Optolong and the Baader seemed to have some halos. I decided on the Optolong. However, I don't have a proper imaging camera and for a while I'll be testing it with the ASI120MM I have. Plans for a larger sensor camera.

Yesterday I received the filter and had some tries on M42. My balcony window opens to NEE so M42 is a tough target. I can only point the scope to it on EQ mode only before it reaches 15deg. So I had to switch to AZ mode where a scope can reach almost out of the balcony with the counterweight bar extended. Very good AP setup.

Anyway, I attached the ASI120MM to a Tair3s lens, wide open this time at F/4.5 and put them on the AZ-EQ5 in AZ mode.

~40x10s + 70x2s. Gain 70/100. With calibration files.

I don't know what to try this evening if it's clear. What do you think about putting the camera on a 135 F/2.8 lens and drizzling 2x? Did anyone of you try drizzling and had a successful result?

Clear skies,

Alex

 

Edit: I don't know what I've done to have the white frame, I didn't notice it until now. It was probably after combining the 10s image with the 2s one.

I was trying to do something similar with my ASI120mm, and found out your post. Thanks for sharing this info, and beautiful pics. I am basically using ASI224MC, and Nikon D5200 DSLR, and getting good results. But I want to try now Hubble palette using Ha, O-ii, and S-ii filters, and am thinking of using ASI120mm for some serious photography work, apart from guiding. I am hoping for good results looking at your narrowband pics. You can see my gallery here on Telescopius: https://telescopius.com/profile/pinakoza

Weirdly the wifi name is ESP_1F4E16. When I connect my PC to it and run ipconfig using cmd, it shows

default gateway: 192.168.4.1

subnet mask: 255.255.255.0

ipv4: 192.168.4.2

Excellent job, many thanks for sharing this great project. Ordered everything more than a month ago, and arrived a week earlier. I put together everything neatly, and connected it to the mount. The wifi started showing up on my laptop, and got connected to it - succeed up to this stage. But when typing 192.168.4.1 in my Chrome/Edge, it won't open up it's webserver! It looks similar problem as described by stash_old. I have also ordered two of the devices, both of them shows their own wifi, but none of them opens up on webserver. Any advice?

This is the ESP8285 ESP-M2 chip that I ordered:
