NINA memory issus

Since january 21st I'm struggling with errors from N.I.N.A. Most of them are related to memory errors. At first I made some changes of the windows settings on memory usage. Next I changed back to NINA 32 bit version. When imaging with my ASI2600MC I kept having the same errors. As a next step I updated following drivers and software:

        - ZWO ASI Native drivers

        - ZWO ASCOM drivers

        - ASCOM Platform

The updates made no difference and I still got errors. I read that the 32bit version of NINA maximizes the RAM memory to 2Gb. So, I went back to NINA64 bit and installed the latest beta version of NINA (64 bit 2.1 HF1 RC005). Executing a dry run went succesfull, even after framing and imaging.   So, so far so good. 

Comet C/2022 E3 (ZTF) widefield

Image of Comet C/2022 E3 (ZTF) from Jan 28, 2023 taken with Nikon D7500 and 130mm. Stacking using APP with 15 pictures each 15s exposure time and different ISO levels. The result was edited with CS4 and DeNoise AI.

The green color is becoming obvious.

Comet C2022 E3 (ZTF) with three tails

When looking more closely at my image of Comet C/2022 E3 (ZTF) I saw a third tail. But I thought this was an artifact created by processing the image. 

Untill today, I never heard about comets having more then 2 tails. I always read that comets have 2 tails, one dust tail and one plasma (ion or gas tail). This morning I read an article on Spaceweather mentioning C/2022 E3 (ZTF) having 3 tails : see this link

So why 3 tails? This phonomenon is an optical illusion weh seeing the comet from Earth. How this happens is explained below (source wikipedia).

As a conclusion, my image of Comet C/2022 E3 (ZTF) has 3 tails, one dust tail, one plasma and one anti tail. Below I added false colors to show more detailed all three tails.

Sunspot AR3190

The huge sunspot AR3190 is about 710MH and visible with the naked eye. Through the thin clouds and with sunglass I was able to see the sunspot.

Sunspot AR3190 has a couple of lightbridges. 

The image was made using TAL200K f/8.5 and ASI290MM. 

Setting : ND3.8 solarfilter, OIII filter and IR/UV filter.

Software : SharpCap 4, AS3!, IMPPG, CS4

Comet C/2022 E3 (ZTF)

 

I waked up at 4h30 to image the comet C/2020 E3 (ZTF). Temperature around -3°C and a layer of 5cm snow. Polar allignement using my guidecamera and sharpcap4. After 3-star allignment I connected with Stellarium and N.I.N.A. When imaging the comet, N.I.N.A. gave an errow which I was not able to fix. As a consequence all pictures made with SharpCap 4.

Setting: TLAPO80/480 f/6 and ASI2600MC

Software: SharpCap, Stellarium, APP, CS4

Lights : 20x45s, 10x60s; Darks 10x45s, 10x60s; Bias 10x; Flats 10x

Comet C/2022 E3 (ZTF)

My first picture of Comet C/2022 E3 (ZTF). The comet is currently in constellation Bootes and moving into constellation Draco. My best estimation is magnitude 6.7 (see magn marked around the comet). The comet is greenish.

Setting: Nikon D7500 24mm f/3.8 ISO1600 15s
